GENERIC TPP SIMULATOR STARTUP PROCEDURE
LOCAL OPERATIONS
This exercise includes some local operations performed outside of the control room by the local equipment Auxiliary
Operator (AO). The local operations are integrated into the exercise because they are critical to unit operations and they
motivate the student by creating an environment that closely resembles actual unit operation.
When requested, the instructor will play the AO role and perform local operations from either the Instructor Station Local
Operation Screens (LOS) or the Command Window.
Local operations that are NOT modeled and DO NOT affect control room indications should be verbally simulated by the
instructor. In other words, upon completion of each action, make the appropriate verbal report to the student on the status
of actions taken.
It is the student's responsibility to ensure the readiness of a system by verifying that all local operations have been
performed and the system components are ready for operation.
At a minimum, the student must perform the following for all local operations:
•
Dispatch the AO to perform the applicable lineups, system starts, etc.
•
Verify that all local operations have been completed before starting any equipment
[]
Option: If the student fails to verify the completion of local operations, the instructor may wish to close
manually operated local valves, dampers etc. This would cause operational problems once a system is placed in
service. For example, close the suction valve of the pump to be started.

Discuss:
1. The condenser should be filled with water and any air pockets in the
circulating water pump discharge piping minimized, or if possible,
eliminated prior to starting a pump. If a circulating water pump is
started with air pockets in the system, pressure pulsations will occur
that can cause rupture and serious damage to the condenser and entire
circulating water piping system.
2. Use of only two Circulating Water Pumps (CWP) will reduce plant
efficiency at any load. In addition, the life of the pump motors and the
discharge valve gear boxes will be reduced if they are to be started too
frequently. Therefore, three pumps should be in service at all loads
provided that they are available. In the case where only two pumps are
available, the unit will still be able to produce 100% load but with lower
efficiency.
Notes:
1. Before startup of the CW system, the Closed Cooling Water, CW Intake
canal system, and at least one condenser loop should be in service.
2. CW Pump discharge valve will open to 37% if only one pump is in
service and will open 100% if two or three pumps are in service.
3. Condenser Fill status will automatically change to inactive if condenser
water box B level > 85% and will automatically open CW-ISV-170A/B
and close CW-VTV-157A/B.

Questions:

Questions:
1. If the Lube Oil System normal operating temperature is between
110 ~ 115°F (43.3 ~ 46.1°C), why is the temperature maintained at 90°F
(32.2oC) during startup?
Answer: During turning gear or low speed operation the turbine
journal can climb the walls off of the bearing then suddenly drop,
causing vibration in the low pressure turbine blades. With the oil
temperature at a lower temperature, the oil is more viscous, thus
supporting the weight of the journal better.

1 ^ 1 Questions:
1 • 1 1. Why are the drum vents closed at 200kPag?
Answer: The drum vents are used to vent oxygen and dissolved gases
from the boiler so they do not react with the boiler tubes to cause
corrosion. At 200kPag, the drum is considered free of air and the
venting process in complete.

1. After a unit outage, boiler steam silica needs to be boiled out before
sending steam to the turbine. This is done by firing the boiler and
establishing steam flow through the Turbine Bypass System. The
bypass will be controlled at a target condition of 130 bar until the
Chemist Technician confirms the silica boil out is complete. After
boiler steam silica requirements are satisfied, the Turbine Bypass
System can be shutdown.
Notes:
1. The HP Bypass if one of the following conditions occurs:
a. Condenser vacuum > 259mmHg
b. HP Bypass line temperature < 121°C
c. Feedwater to Reheater differential pressure < 10bar
2. When steam flow > 20%, the "Loss of Reheat Protection" will be
armed. The protection will only be disarmed when an MFT occurs.
Thus, in order to prevent arming, the steam flow should be maintained
below 20% during operation of the Turbine Bypass System.

1. Each pulverizer needs to be warmed before coal is fed into the
pulverizer. Adequate warming requires that the outlet temperature of
the pulverizer be maintained at >60°C for at least 15 minutes.
2. At low loads (low Hot Primary Air Temperature) only one pulverizer
can be warmed at a time. Warming for the next pulverizer can be
initiated once the first pulverizer is placed in service with a feeder
demand > 30%. After two pulverizers are in service, it is possible to
warm two pulverizers at a time.
3. Pulverizers should be warmed in the sequence in which they will be put
in service. The typical sequence for placing Pulverizers in operation
during a Cold Start is as follows:
a. Pulverizer B
b. Pulverizer C
c. Pulverizer D

2.
Equalizer Valves - The equalizer valves opens on a turbine trip
when the closed end position switch indicates that all reheat stop
and intercept valves are closed. The valve vents the intercept
valve balance chamber to the condenser, and reduces pressure to
allow reopening of the reheat stop valves.
Why don't the rotor and the shell expand or contract at the same rate?
Answer: The rotor expands and contracts faster than the shell because
it is less massive and has more surface area exposed to steam flow.

Notes:
1. Generator Synchronization Notes:
a. Automatic Synchronization (automatic closing of the Generator
CB) is normally selected to synchronize the unit. If Automatic
Synchronization is not available, Manual Synchronization may be
selected.
b. The generator should be operated within the generator capabilities
curves furnished by GE.
c. Do not overload the generator beyond maximum stator current
rating of 21,242amps.
d. Manual Synchronization means that the Generator Breaker is
manually closed from the ECP (using hand switch CS 52G7) while
the turbine speed matching and excitation controls are in auto.
Manual Synchronization is only used when Auto Synchronization
is not available.
e. Caution must be used not to close the generator breaker when the
generator is more than 10o out of phase with the grid. Such closure
is likely to result in damage to the generator.

Questions:
1. Why is hydrogen used to cool the generator?
Answer: Hydrogen is better at removing heat than most other gasses.
Also because it is lighter than all other gasses, it requires less energy to
circulate and produces reduced windage losses.
2.
If the voltage of the generator is too low when the generator breaker is
closed, will the generator be over or under excited?
Answer: Under excited. When under excited, the generator is drawing
Vars from the system in order to bring voltage up to the voltage of the
bus. If grossly under excited the generator may slip a pole which can
cause damage to the rotors

1. The Minimum Load point is ~80 GMW and is the point where the ATS
examines turbine stress to determine if a load hold is required.
2. Load Increase Notes:
a. Closely monitor Main Turbine operating parameters such as
Turbine Stress, Vibration, Bearing temperature, etc during load
increases.
b. At low loads (with one or two pulverizer already in service), flame
voting must be observed carefully before startup or shutdown of an
oil elevation. Verify that the flame voting indications are healthy
on the OIS Flame & Damper (FLMDMP) screen.
c. It is better to put oil guns in service for an elevation above the
existing coal firing elevation rather than below.
d. Ensure warm up oil pressure is greater than 900kPag.
3. Main Steam Pressure should be gradually increased as load is increased.
The control point for the Main Steam Pressure is controlled by the CRO

Questions:
1. What indicators does an operator have to determine when it is
time to place additional equipment in service?
Answer: Equipment demand (on M/A stations) and the current vs.
target load. Additional equipment is started as the demand on
operating equipment approaches 70%. Also, additional equipment is
started if the capacity of currently operating equipment is not enough
for the target load.

In general, it is important to keep the individual pulverizer feeder
demand at > 50%. This helps ensure stable combustion. Coal firing on
each pulverizer should be initiated in anticipation of loading and
maintaining feeder speeds at > 50%.
Each feeder delivers approximately 89TPH of coal at a demand of
100%. One TPH of coal will deliver approximately 2.3MW. Thus,
each pulverizer with a feeder demand of 50% will deliver about
100MW.
Coal Firing notes:
a. Pulverizer must be warmed up so that the mill outlet temperature is
at the setpoint of 72°C for a minimum of 15 minutes before coal
feeding. After coal feeder has been placed in service, gradually
reduce temperature setpoint to 66°C.
b. If a pulverizer trips at load, pulverizer inerting and steam transport
shall be carried out. (Refer to POI-BF-05).
c. Put additional (adjacent) feeder in service when existing feeder
demand is greater than 70%
d. Do not leave pulverizer in low load (< 40%) operation for extended
periods of time (> 20 minutes.) Bring pulverizer load above 40%
as soon as practical.
Mill trip conditions:
a. Mill outlet temp > 120°C
b. PA Flow < 52%
c. Pulverizer to furnace DP < 0.4kPag
If pulverizer bowl DP > 3.6kPag, feeder will run down to minimum
25%
