Subject: City of Vernon, Extension
Dear Ramon,
We appreciate the continued confidence in ALSTOM Power and we are looking forward to
be working with you in this extended scope, forming power island package together with
the gas turbines.
We understand the urgency in getting the documentation required for your permitting
process in place, and hence, ALSTOM Power is committed to provide the information
related to our equipment by mid September for this purpose. Please note that this
information will be preliminary since some information and drawings might change during
the project phase, During our meeting in Denver we discussed the possibility of issuing a
purchase order for this information. Since we understand that speed is critical here, we
think that the legalities of such a contract might slow down this process and also
complicate this issue more than necessary, and therefore, we will take on this
responsibility without a formal purchase order. Please find enclosed the list of information
required for the permitting, as provided in the meeting in Denver. We've marked the
information we will submit and assume that others will supply the balance of information.
Further, ALSTOM Power recognize the value and the convenience for the City of Vernon
to get a total power plant performance guarantee, with associated project management /
administration and heat balance engineering, optimization and coordination of the total
ALSTOM Power scope. Therefore, ALSTOM Power will provide an overall wrap around the
performance guarantee document associated with the extension, i.e. the steam turbine
and the HRSGs, and the original base scope, i.e. the gas turbines. This wrap around
responsibility and coordinating effort will be included in the price for the equipment.

The extended scope consists of two HRSGs with associated emissions control equipment
in order to meet the required levels imposed by the authorities and one steam turbine with
associated generator and control system. For more details about the scope of supply,
please refer to the enclosure to this letter.
ALSTOM Power recognizes the importance for the city to be able to come on line with the
power plant during the summer of 2003. In order to support that, and based on a
confirmed, effective order date not later than September 10, the following delivery time
schedule has been developed, subject to prior sales:
Component Delivery time DDP site
Steam turbine December 23, 2002
HRSGs October 8 — November 5, 2002
Further, in addition to the above delivery schedule, ALSOM Power will make provisions for
later delivery of the gas turbines to site, in order to fit into the overall combined cycle power
plant time schedule. The new delivery time for the gas turbines is between August 15 and
September 1, 2002. Please note that the dates for payments relating to the original
delivery schedule are still valid.
The price for this extension, as outlined in this letter, will be submitted Friday September 7,
2001. This price will in principle be based on the terms and conditions negotiated for the
gas turbine contract.
We trust that you find this extended package interesting and we are looking forward to be
working closely together with you in this, for ALSTOM Power, very important project.
Yours truly,

Running up sequence
Running up is guided by the temperature difference at the time when opening ESV.
• dT = jTr--Tmj (absolute temperature difference)
• Tr = Steam temperature rated condition
• Tm = Metal temper ature measured in turbine casing
• Ts = Steam temperature measured in main steam line between boiler outlet
and turbine.
Start-up is not allowed until Ts is greater than Tm-50 degC. (Use turbine by-pass to
raise Ts)
Delay in running up may show up due to low oil inlet temperature or high vibration
level.

Turbine Protection System
1. GENERAL
The purpose of the Turbine Protection System is to protect the installation when
abnormal operation conditions occur making a continued safe operation
impossible.
The Turbine Protection System comprises two separate parts, one electrical and
one hydraulic part.
The electrical section consists of a digital controller, with corresponding power
-supply and 1/0 modules, and three redundant speed monitoring channels.
The hydraulic part consists of a high pressure hydraulic oil system, powered by
two redundant pumps. The interaction between the two sections is the electro-
hydraulic solenoids valves. The Turbine is tripped when the hydraulic trip oil is
a
drained by de -energizing the solenoid valves, causing the servos to quick -close
s
the steam valves.
Also a planned shutdown is carried out utilising the turbine protection system.
The electrical (controller) and the hydraulic oil system are described in separate
documents.

situation each speed monitoring channel will de -activate its trip solenoid valve,
causing it to open. The nominal set value of the overspeed tripping device is
110% of nominal speed.
Testing of overspeed trips is carried out by increasing the actual speed to the trip
levels.
Each speed monitoring channel can be tested on line, simulating an overspeed
signal from the pick-up by adding a virtual additional 10% speed to the signal.
The corresponding trip solenoid valve will then be de -energized and indicate
correct function.
The speed monitoring channels supervise the speed pick-ups and give an alarm in
case of faulty pick-up.

By using microcomputers for protection functions, it has proved possible to '
perform the different protection tasks extremely reliable. The calculating capacity
makes it possible to realise calculating protection functions such as protection
against low !4Pgree of superheated steam, time depended protection function etc.
Availability of the steam turbine generator can be increased since the system can
perform a more accurate evaluation of the different trip functions.
In general the software in the system is built up around one main trip gate where
all the individual trip functions are connected.

The main parts of the Turbine Controller (governor) are the Controller Section,
comprising the subparts Controllers and Limiters plus Selectors, and the Valve
Position Controllers, which comprise the subparts Split Range Units and the
actual Valve Position Controllers.
The turbine governor Controller Section includes a number of controllers and
limiters, each dedicated to a defined function, for example frequency/output
control, inlet steam pressure control, load limitation, etc.
A controller, as well as a limiter, compares a set (desired) parameter value with
the actual measured value. If a deviation exists, the controller/limiter produces a
signal causing the controlled valve to move in the direction required to eliminate
the deviation. For a controller, the set value is generated within a set value
generator.

STFrwnber Ethan Doc Ksd
4400-06E 2 SD
The set value generator is controlled by an external set value sent from the
Operator Station (by the operator) via the turbine automation node. A limiter
normally has a fixed set value and thus no set value generator.
All controllers and limiters, are of the proportional -integrating type, i.e. PI
controllers.
The typical characteristic of a PI controller is the lack of steady state control
deviation, i.e. a very accurate control.
The different controllers and limiters interact through a number of selectors. The
selectors are either of the Minimum Selection Type - i.e. a selector allowing the
lowest of two or more signals to pass - or the Maximum Selection Type - i.e. a
selector allowing the highest of two or more signals to pass. Thus, changeover
from one controller function to another is accomplished by increasing or
decreasing the set value of one controller or another. This principle eliminates the
need for controller function selector switches and also results in bumples transfer
from one mode of control to another.
The valve position controllers, one for each governing valve, are PDP controllers
receiving the output from the controller section as set value and the actual
governing valve position as feedback. The position is measured with an electronic
� e �a transducer. The valve position controller output is fed as a current to the electro-
► i E hydraulic converter in the governing valve servo motor. Here, the. signal is
converted to an oil flow proportional to the current, an oil flow which will
: m position the governing valve in the position required by the limiter or controller in
action.
In the event of loss of control signal, a mechanical bias in the electro hydraulic
converter will cause the control valve to close. The valve will also close if the
valve position feedback is lost.
Below follow a short description of the most common controllers and limiters
(base configuration):
Run-up Controller
The run-up controller is a speed controller used for running up the turbine from
standstill to nominal speed. The controller can either be run in automatic mode or
manually.
Frequency/Output Controller
The frequency/output controller will maintain the turbine at a desired speed when
operating in isolation from an external grid or at a desired output when
synchronized to an external grid

Step/Gradient Limiter, Loading
The step/gradient limiter will prevent too rapid opening of the governing valves,
thereby reducing the thermal stress of the turbine. The two fixed set values for
step and gradient, respectively, are preset according to limitations valid for the
turbine in a hot state.
Minimum Output Limiter
The minimum output limiter is connected to maximum selectors in such a way,
that it overrides other controllers and limiters (in all control mode) capable of
reducing the steam flow below min. steam flow through the turbine.
Minimum Boiler Pressure Gradient Limiter
The Minimum Inlet Pressure Gradient Limiter will prevent the turbine from
demanding more steam than is produced in the boiler, thereby causing a rapid
drop in live steam pressure, temperature and/or water carry-over from the boiler
to the Turbine.
By throttling the Turbine Main inlet valve(s) the boiler pressure will be limited to
an acceptable decrease rate.

The Minimum Inlet Pressure Gradient Limiter uses the actual inlet live steam

maximum rate of change of the set value at decreasing inlet pressure is set to
`
30/o/min of nominal turbine inlet pressure. The inlet pressure set value has, a
turbine inlet
minimum value limit, normally set to 35% of the nominal pressure.
The number of controllers/limiters varies of course depending on process
configuration/requirements.

selectors are either of the Minimum Selection Type - i.e. a selector allowing the
lowest of two or more signals to pass - or the Maximum Selection Type - i.e. a
selector allowing the highest of two or more signals to pass. Thus, changeover
from one controller function to another is accomplished by increasing or
decreasing the set value of one controller or another. This principle eliminates the
need for controller function selector switches and also results in bumples transfer
from one mode of control to another.
The valve position controllers, one for each governing valve, are PDP controllers
sreceiving
the output from the controller section as set value and the actual
"
governing valve position as feedback. The position is measured with an electronic
transducer. The valve position controller output is fed as a current to the electro-
is
s
hydraulic converter in the governing valve servo motor. Here, the signal
$
converted to an oil flow proportional to the current, an oil flow which will
position the governing valve in the position required by the limiter or controller in
action.
In the event of loss of control signal, a mechanical bias in the electro hydraulic
converter will cause the control valve to close. The valve will also close if the
valve position feedback is lost.
Below follow a short description of the most common controllers and limiters
(base configuration):
A
Rim -up Controller
The run-up controller is a speed controller used for running up the turbine from
standstill to nominal speed. The controller can either be run in automatic mode or
manually.
Frequency/Output Controller
The frequency/output controller will maintain the turbine at a desired speed when
operating in isolation from an external grid or at a desired output when
synchronized to an external grid

Step/Gradient Limiter, Loading
The step/gradient limiter will prevent too rapid opening of the governing valves,
thereby reducing the thermal stress of the turbine. The two fixed set values for
step and gradient, respectively, are preset according to limitations valid for the
turbine in a hot state.
Minimum Output Limiter
The minimum output limiter is connected to maximum selectors in such a way,
that it overrides other controllers and limiters (in all control mode) capable of
reducing the steam flow below min. steam flow through the turbine.
Minimum Boiler Pressure Gradient Limiter
The Minimum Inlet Pressure Gradient Limiter will prevent the turbine from
demanding more steam than is produced in the boiler, thereby causing a rapid
drop in live steam pressure, temperature and/or water carry-over from the boiler
to the Turbine.
sBy
throttling the Turbine Main inlet valve(s) the boiler pressure will be limited to
an acceptable decrease rate.
The Minimum Inlet Pressure Gradient Limiter uses the actual inlet live steam
The
pressure value, connecting it to a ramp function and creating a new set value.
maximum rate of change of the set value at decreasing inlet pressure is set to
2
301o/min of nominal turbine inlet pressure. The inlet pressure set value has a
minimum value limit, normally set to 35% of the nominal turbine inlet pressure.

The number of controllers/limiters varies of course depending on process

Shaft Vibration and Position Monitoring
STFnurtbar Edition Doc Kind
4400-15E 2 SD
Shaft Vibration and Position Monitoring System
General
Shaft vibration is monitored by means of transducers adjacent to the bearing housings of
-- turbine and generator. The transducers measure the vibrations of the shaft relative to the
bearing housing.
The turbine modules as well as the generator are equipped with two transducers at each
bearing.
Gears are equipped with one accelerometer.
Further, there is a Key Phasor®i to determine the shaft angle on each of the turbine
shafts.
A high vibration level on any of the above transducers will cause an alarm. An
excessively high vibration level on any of the transducers will trip the unit.
Vibration and Shaft Position Measurement
Vibrations and shaft positions are measured as peak -to -peak amplitude expressed in
microns or mils.
Measuring Equipment
The proximity transducer consists of a proximity probe and a preamplifier or signal
converter, (Proximitor®"). The proximity transducer works on the eddy current principal.
A radio frequency is generated within the proximitor and sent via a special cable to the
probe where it is radiated into the observed material, setting up eddy currents. The return
signal is then fed back to the proximitor and the loss of energy is measured. The same
type of proximity probe and proximitor is also used as a key phasor and for shaft position
detection.
The proximitor is mounted in a junction box locally on the unit. The input signal from
the proximity probe is linearised and fed via conventional shielded cabling to the monitor
mounted in the turbine control cubicle or separately in the control room.
proximotore and Key phasor® are registrated trade marks of the Bently Nevada Corporation

Shaft Vibration and Position Monitoring
STHiunber Edson Ooc. Kind
4400-15E 2 SD
For the gear the vibration measurement is carried out by Acceleration Transducer
System.The accelerometer uses a piezo-electric crystal situated between the
accelerometer base and an inertial reference mass. When the accelerometer is mounted
on the gear casing, machine vibration causes a compression or tension force to act on the
crystal. The crystal, in turn, acts as a precision spring to oppose the compression or
tension force. The crystal thus generates a displaced electric charge. An integral amplifier
converts the charge to voltage..
The monitor will give an analogue output of the shaft vibration level to the turbine
protection system, where the alarm and trip limits are programmed. The actual vibration
levels are displayed on the screen of the operator's workstation.

Lubrication System, Geared Units
General
The lubricating oil skid is built up from standardized components to form a complete
sytem to provide the turbine generator unit with lubrication oil. The tube oil skid is
factory assembled, complete with all main components of the system, including
automatic temperature control, oil pressure adjustments, and instrumentation wired to a
junction box. Dual main oil pumps, emergency oil pumps, oil coolers and oil filters allow
continued turbine generator operation while maintaining these components.
The factory assembled skid, and the pre -fabricated lube oil piping, sets the stage for a
short site installation time. The oil reservoir, the piping downstream the filters and the
return oil piping are made of stainless steel.
Type of lubrication oil: Turbine oil, ISO VG32 (standard) or ISO VG46 (option).
The picture below is typical only and intended to support this description.

Lube oil supply unit
The unit comprises Lube oil reservoir with oil vapour fan, oil pumps, oil coolers,
temperature control valve, oil filters, valves and interconnecting pipes.
Start and normal operation.
Two 100 % AC driven centrifugal pumps (one standby) sets up the oil pressure. The oil
temperature is controlled by the temperature control valve, which mixes cooled and
uncooled oil to a correct temperature.
The two 100 % oil coolers are connected in parallel both on the oil side and on the water
side.
Before leaving the skid, oil is filtered by passing a dual oil filter (each 1001%) - exchange-
able during operation.
If the main pump stops, the standby pump starts automatically.
Emergencies
a
Loss of both main pumps trips the turbine and starts a DC driven centrifugal pump.
f t
The emergency coast down pump, which is a continuously running hydraulic motor
driven screw pump, supplies emergency oil to the bearings down to 20-30 /a of nominal
F
turbine speed. The required oil for the last coast down period is furnished by the DC
a
PUMP,
This means that, during the most critical part of an emergency situation, there are two
g
independent pumps operating to secure the oil supply.
Hill
Instrumentation and monitoring
Supply oil pressure, supply oil temperatures, and oil level are supervised. The
g
negative pressure in the reservoir has local indication.
Alarms are given for low pressure (starts the standby pump), high temperature, high/low
tank level, and filter differential pressure.
Extremely low oil supply pressure, high oil supply temperature or extremely low oil tank
level trips the turbine.
There are also local gauges installed.

Drains for Condensing Steam Turbines
Classification of drains
General
The drain system transports water from locations where steam tends to condensate or
water tends to accumulate during start, operation and stand still. The system thus
prevents accumulation of water which could give rise to damageing water hammer, cause
erosion or unforeseen steam flows when this water gets evaporated when the pressure
decreases.
Drain from pipes and valves, the turbine itself and associated apparatus are classified into
two groups - external and internal drains - as shown in Fig.l and outlined in the text
below.
These two classes of drains must never be interconnected due to the risk of back flow of
steam or drainage to the turbine. This is particularly important if for some reason the
turbine is shut down for maintenance for a long period of time. On these occasions it
must be possible to isolate the turbine completely from all external systems to be able to
work with the turbine. Also if the turbine is shut down wet steam can cause severe
corrosion to the turbine internals.

Internal drains
Internal drains are defined as
• drains from the turbine
• drains from lines connected to the turbine, valves and apparatus, provided that they
are isolated from all steam sources when the turbine is shut down.
The internal drains are connected to the condenser or to a drain tank which in turn is
connected to the condenser.
The internal drains must not be connected to the atmosphere due to the risk of air leakage
back through the turbine to the condenser during vacuum raising.
Example of internal drains:
• Lines between the governing valves and the turbine
• Turbine casing drains
• Interconnecting line between turbine modules
I
• Gland steam line downstream of an isolating valve
• Gland steam condenser
• Extraction lines which can not be pressurised when the turbine is shut down.
• Condenser for steam driven ejector.

Most commonly the external drains are connected to an atmospheric drain tank from

where the drain is dumped or pumped back into the condensate line.
External drains must never be led to the drain tank for the internal drains. This could
result in steam or water from this tank being forced backwards up into the turbine and
causing severe corrosion to the turbine internals if the turbine is shut down for
maintenance etc. Also it must be possible to isolate the turbine and condenser from
external systems to be able to do maintenance on the turbine
Example of external drains:
• Emergency stop valve casing and live steam line up -stream the governing valves.
• Gland seal line up -stream an isolating valve.
• Auxiliary steam lines up -stream isolating valves.
• The parts of extraction steam lines which might be pressurised when the turbine is
shut down.

Drain tanks for internal drains
The drain tank must be placed at a level sufficiently below all drain points. All lines
carrying drainage to the tank must be installed with continuous slope to prevent water
from accumulating in the lines during e.g. standstill and start-up.
The drain tank must be connected to the condenser. The flash line from the drain tank to
the condenser must be dimensioned so that the pressure drop is negligible also with all
drains to the tank open. Otherwise there is a risk that pressure build-up in the tank might
cause back -flow in some drains.
Special attention must be paid to the pressure drop when automatic drain valves are used
which remain open up to part load (about 15 0%).
In the cases where the drain tank is situated so that it can not be drained to the condenser
hotwell by a loop seal, the drainage must be pumped to the condenser.
The tank must not be open to the atmosphere since it constitutes a part of the plant
e
subject to condenser vacuum.
Additional cooling might be required in the tank to keep the steam temperature in the
flash line to the condenser below the condenser design temperature. Normally, cooling is

tank to the condensate line.
The vent line to the atmosphere must be dimensioned to give negligible pressure drop
-with all drains open to the tank: Otherwise there is a risk of pressure build-up in the tank
which can cause back flow into the drains.

Drains
General
All drains shall be piped individually to the drain tank, condenser etc. They must not be
grouped together to a header since this could cause drains with lower pressure to choke
and even to back flow.
All drains have to be designed to withstand condenser vacuum at the start of the drain
pipe. Consequently a drain line must not be designed in such a way that it relies on a high
steam pressure to force the drainage to the tank or the condenser.
When pneumatically operated valves are used, an orifice shall be erected after each valve
and as close as possible to the flash box of the condenser. Minimum size of the orifices is
7 mm (0.28")
Drains from Turbine, Valves and Pipes
Each of these drains is equipped with a steam trap or a pneumatically operated shut-off
valve that is kept open during standstill and up to a preset load limit high enough for the
° turbine casing etc. to have adopted a temperature well above the saturation temperature.
In cases where there is a need for draining during normal operation as well, .there is a
steam trap in parallel with the shut-off valve.
The drain pipes are to be installed with continuous slope to prevent water from
accumulating in other parts than the loop seals.

Steam Purity Requirements for Turbine'Operation
General
Water and steam of sufficiently high quality are necessary for reducing the risk of
corrosion and deposits in the boiler and turbine. This is achieved by using good make
up and feed water treatment. Careful supervision of the feed water system and steam
boiler is therefore very important, also for ensuring the reliability and availability of the
turbine. The steam quality requirements are independent of the boiler pressure and
temperature. The specified values must be maintained if the expectations of continuous,
trouble -free operation of the turbine are to be met.
To avoid deposits, it is particularly important to ensure that the contents of silica and
alkali are sufficiently low. Deposits always result in reduced efficiency. In particularly
adverse cases, deposits may also involve the risk of damage.
In order to safeguard a sufficiently high quality of the water and steam, adequate
a
supervision must be provided. Continuous measurement of cation conductivity of the
steam is a.minimum. requirement.
Demands on the Turbine Steam

The steam quality requirements serve as a basis for determining the guideline values for

given in "Guideline values for boiler water", and "Guideline values for feed water".

EXPLANATION OF STEAM REQUIREMENTS
Transport of impurities
Impurities in the steam cause deposits and corrosion.
The steam can be contaminated by mechanical carry-over of boiler water, by the use of
contaminated water for spray attemperation, or by the solubility of the impurities in the
high pressure steam.
In order to maintain an acceptable level of salt carry over, it is important to ensure that
the water separators in the steam paths of the boiler are sufficiently effective, and that
boiling -over, foaming and over -feeding of the boiler are avoided.

even cause damage.
Deposits in the turbine may be soluble or insoluble in water or saturated steam.
Sodium hydroxide is an example of a soluble salt. Sodium hydroxide should normally
be limited to less than 1/10 of the total salt content of the boiler water. High contents of
sodium hydroxide in the deposits in the turbine may cause corrosion.
Typical water insoluble deposits include silica, copper oxides and iron oxides.
The solubility of silica in steam is relatively high even at low pressures, and silica will
be deposited in the low-pressure turbine if its content in the steam is in excess of 0.02
mg/kg. The concentration of silica in the feed water and boiler water must therefore be
kept under control. Even temporary excursions beyond the specified maximum
concentration in the steam may lead'to deposits in the turbine.

Corrosion
Corrosion attack may occur in the turbine if the steam contains corrosive salts or
corrosive gases such as carbon dioxide.
Hydrazine is often used for residual oxygen removal after mechanical deaeration. At
high temperatures, hydrazine decomposes into nitrogen and ammonia. Ammonia may
give rise to corrosion damage to copper -alloy condenser tubes.
Sodium sulphite should not be used for residual oxygen removal at pressures above 35
bar, since it may decompose into aggressive sulphur compounds.
Large quantities of bicarbonates can be prevented from entering the boiler by
appropriate feed water treatment. These salts decompose to form, among others,
carbon dioxide which is entrained by the steam and makes it corrosive.
i;
i
During stoppages, the turbine should be kept dry in order to avoid shut -down
o
corrosion of the rotors and blades.
GUIDELINE VALUES FOR BOILER WATER
In order to meet the demands made on the steam, the feed water and boiler water must
62 bar,
be treated. Demineralized water can always be used. At boiler pressures below
g
softened water (salt -containing water) can also be used as make-up water.
Table 2 gives guideline values for boiler water originating from salt -containing and
salt -free feed water.
Boiler water from salt -containing feed water
The guideline values should be adjusted on the basis of operating experience.
Experience has shown that certain plants perform satisfactorily only when the actual
values are substantially lower than the tabulated maximum values. The value of
p-alkalinity is given only for guidance. The p-value is explained in Page 11,
(Explanation of guideline values).
Phosphate and sodium hydroxide, if any, are dosed into the boiler. The phosphate
treatment removes the residual hardness and raises the pH. The sodium hydroxide
only raises the pH. If sodium hydroxide is dosed, a very careful check must be kept on
the excess sodium hydroxide.

EXPLANATION OF GUIDELINE VALUES
Explanations of the guideline values for boiler water and feed water are given below.
Conductivity
Conductivity is the most important parameter for supervising the purity of steam,
boiler water and feed water.
Silica
I
The permissible content of silica and other impurities in the feed water for once -
through boilers and in the boiler water of drum boilers is determined by the demands
made on the steam.
�s
Iron and copper
Hf
Iron and copper in the feed water and the steam are indicators of how well the water
E
treatment performs: The contents must be kept low, since these elements may cause
deposits in the boiler and turbine.
Sodium
The sodium content originates from additives, cooling water leakage, contaminated
return condensate and problems in the regeneration of ion exchangers. It is important
to keep a good check on the sodium.

0700-01 E 3 SD
P-alkalinity
This value includes all the hydroxide content, but only half the carbonate content.
The P-alkalinity is measured by means of a titration with standard acid solution in the
presence of phenolphtalein
PH
The pH value is a factor which is decisive to corrosion in the water and steam
systems. Solid alkalising agents (sodium phosphate, sodium hydroxide) and volatile
alkalising agents (such as hydrazine and ammonia) are dosed in order to increase the
pH.
Phosphate
Phosphates are dosed in order to raise the pH value and, if salt -containing feed water
is employed, it binds the residual hardness. It is important to avoid over -dosing due to
the risk of carry-over of sodium salts to the turbine.
Oxygen
The oxygen content should be maintained at the recommended values. Oxygen may
otherwise cause corrosion problems.
Content of organic substances
The potassium permanganate consumption and TOC (Total Organic Carbon) are
measures of the organic substances in the boiler water. The content of organic sub-
stances should be kept as low as possible to avoid the risk of their decomposition to
organic acids.
