TESTING AND COMMISSIONING.

1.8.3 THEORY OF OPERATION

a. The controller will modulate the unit cooler water valves to a set point and reduce humidity and wastewater sent downstream. This will increase the temperature in the air housing, and reduce condensation.

Water flows will be monitored to be able to ensure enough water supply to the HVAC heat pump header piping, and that they are above the unit running minimum flow rate. Water temperatures will be monitored to measure heat extraction from the units and to ensure water temperatures are above the minimum for the HVAC system. Air housing humidity level will be monitored as well as ambient temperatures to increase air housing temperature above the dew point where possible.

b. The generator cooling system PLC will operate in three modes, Hand, Off, and Auto. Units 1-6 will have a slightly modified operation control scheme than Units 7-16 as described below. There will be a PLC installed at each unit. Each unit will have a dedicated Hand/Off/Auto control switch, which will be used to select between modes of operation described below. Because the valves fail to the open state, upon power loss, (full open with no control) they will open, and the existing manual control valve will need to be operated to control the flow when in Off mode.

1.8.3.1 Hand Mode

In "Hand" (also known as "manual") mode, the generator and thrust bearing motorized valves will be set to full open from the cooling system PLC; the existing manual valves will need to be operated to restrict or supply water flow for the unit. Process values will still be logged by the controller and available to the repeating analog and digital outputs to GDACS but will not impact controls. Unit heater will operate as described below in Unit Heater Control Section.

1.8.3.2 Off Mode

In Off mode, the motorized valves will be set to full closed from the cooling system PLC. Unit heater will operate as described below in Unit Heater Control Section.

1.8.3.3 Auto Mode

a. In Auto mode, the controller will modulate the generator cooler valve based on cooling requirements of the units, the HVAC header (Units 1-6 only), the dewpoint and setpoints. Certain setpoints should be user configurable within range indicated on the drawings. Setpoints shown are approximate, the final values will be determined during commissioning. Thrust bearing modulating valve will be controlled separately from generator cooler valve based on thrust bearing RTD input.

b. Units 1-6 also provide water to the HVAC heat pump header. They will operate in a slightly different manner, described below. Automatic control schemes will prioritize unit cooling and operation over HVAC needs; cooling will not be restricted to units when temperatures/load demand additional cooling supply, even if it is outside the HVAC input needs.

1.8.3.4 Unit Water Control

a. For all units, cooling water will be enabled when running, and reduced / off when offline.

b. Startup: When a unit is brought online, the control valves will open fully for 10 minutes (user configurable), then go to the set position based on the PID control loop for unit temperature. This will actuate the valve and remove any debris from the valve body, as well as flush the coolers and piping of some residual sediment.

c. Operation: A PID control loop (Proportional, Integral, Derivative) will provide valve output control to maintain air housing and stator core temperatures where feasible. When the temperature gets above or below the target abilities of the system, a second set of setpoints will override the control loop and open the valve fully. This will ensure a unit is not starved of cooling water; it is better to overcool a running unit than undercool a running unit.

d. If the humidity in the room is such that the dew point is being approached, generator cooling water flow will be restricted to raise the temperature above the dew point. The dew point control will be overridden when unit cooling demands; this is to say the dew point control will be a desired outcome for the control loop, but cooling requirements reign, even if some condensation is to occur. Condensation would be minimal in these cases, as the stator and rotor would be providing heat to the room, raising the dew point.

e. Shutdown: When a unit is shut down, cooling water will flow until stator temperature reaches a determined setpoint to remove latent heat from the unit. After the cooldown period, the flow will be restricted.

A minimum flow setpoint will be operator configured. Online and Offline minimum flows will be separate setpoints. Online setpoint will match existing minimum flow alarms, and offline flow setpoints will reduce debris settling and biofouling opportunities (Zebra Mussels, mud, etc.)

within the cooling tubes. They can be independently controlled and set to zero if needed. Generator coolers flow and thrust bearing coolers flow will have separate setpoints.

1.8.3.5 Unit Heater Control

Unit heaters will be turned off when a unit is running and turned on when the unit is shut down, and the air housing / stator temperature is below desired setpoint. Air housing temperature sensors will be installed on the inside of generator barrel, across air coolers. The Unit heater setpoint will differ from the cooling water setpoints as the stator coils may need to be heated to reduce condensation and water absorption while in shut down state.

1.8.3.6 Units 1-6 Controls

a. Units 1-6 supply water to the plant's HVAC system. The HVAC system has minimum flow, temperature, and pressure needs for proper and efficient operation. Operating below the HVAC process values will decrease HVAC efficiency, or in extreme cases the HVAC will shut down.

b. The plant operation and river water temperatures have been evaluated, and while no risk is possible to eliminate, the likelihood of the combined Units 1-6 not being able to supply water within the HVAC needs window is unlikely. A detailed cooling water discharge analysis indicate river water and cooler temperature through the unit were above minimum temperature needs and above flow requirements in the years analyzed.

c. When the HVAC demand is on, the units will supply water into the HVAC header as well as the discharge piping. The controllers will ensure minimum flow and temperatures are met for the HVAC system.

d. A minimum flow, pressure, and temperature setpoints will be operator configurable. Online and offline minimum flows will be separate setpoints. Online setpoint will match existing minimum flow alarms, and offline flow setpoints will reduce debris settling and biofouling opportunities (Zebra Mussels, mud, etc.) within the cooling tubes.

Should more flow be required for the HVAC system, units 1-6 will increase their valve positions until the flow is met, under the condition that unit air temperature stays above humidity dew point average by a set amount to prevent condensation. Online units will be providing required flow, offline units will not increase their flow upon HVAC demand. Unit 1-6 cooling controllers will utilize produced and consumed tags to coordinate flow to HVAC. In the case that online units can't meet HVAC flow demand, generator bypass valve, present at each unit with HVAC header connection, will have to be operated to provide more flow.

1.9 COORDINATION

The drawings indicate the extent and the general location and arrangement of equipment and wiring. The Contractor must become familiar with all details of the work and verify all dimensions in the field so that the equipment must be properly located and readily accessible. Panels, and other equipment and materials must be located to avoid interference with mechanical or structural features. If any conflicts occur necessitating departures from the drawings, details of and reasons for departures must be submitted and approved prior to implementing any change.

1.10 SHOP DRAWINGS

Shop drawings must be furnished no later than 30 calendar days prior to installation date. Provide updated and complete as-shipped drawings at the time of final factory testing. The Owner's Representative must review the drawings against the panel construction at the time of final factory testing. Drawings which do not reflect the actual construction of the panel will need to be revised and reviewed again by the Owner's Representative against the actual construction prior to shipment of the panel to the job site. 'As shipped' drawings which require revisions must be submitted to the Owner's Representative for review prior to the actual field review of these drawings against the panel construction. This process of revision and review of the drawings will be repeated as necessary to produce drawings which reflect the actual construction of the panel at the time of shipment. Do not ship panels to the site until the 'as-shipped' drawings are updated, complete, and reflect the actual 'as-shipped' status of the panel. Shop drawings must be dimensioned, to-scale, and show:

a. Panel layout

b. Arrangement, connection, and interconnection of PLC system components

c. Conduit Layout

d. Cable and Conduit Schedule

e. Wiring access locations

f. Wiring diagrams

g. Instrument loop diagrams

h. Schematics
