1.7.1 General

The power module shall include the necessary switchgear and controls required for manual operation and automatic operation in parallel with other power modules and with the utility power source. The system shall be designed to provide power into the base electrical distribution grid system as a prime power source, independent of the utility in the normal mode of operation. The circuit breakers used as the generator main breaker shall be vacuum type. No other types shall be allowed.

The contractor shall perform a protective device coordination study for approval. The study shall start at the reclosers and continue back to the generators. The study shall include time-current curves, short circuit calculations and a report of recommendations and device settings. The complete study including one-lines shall be provided to the Base after approval.

1.7.2 Control and Monitoring

The existing government furnished PLC and kWH power metering equipment shall be utilized to control and meter the generation plant to the extent possible.

Each power module generator set must be able to be started and stopped by signals from a remote location by signals from the existing power plant Programmable Load Controller (PLC). Each module shall have a Remote Terminal Unit (RTU) to interface the individual module to the Programmable Load Control unit (PLC). If other than the existing controller is to be proposed then the PLC may be located in one of the modules or remotely as desired.

The PLC will monitor system wide conditions, starting and stopping each module in response to system requirements by sending start-stop signals to each module RTU. The remote signal I/O shall be a voltage free, momentary contact to initiate operation and a separate voltage free, momentary contact to cease operation. Upon receipt of the initiate signal, the generator set shall automatically start and synchronize with the other sources, if any, on the utility grid. Once in synchronism, the generator circuit breaker shall automatically close and the generator set shall softly load up to its pre-programmed or rated capacity. The generator shall continue to operate with output determined by the switchgear loading control. Upon a signal to stop, The generator shall softly unload, the circuit breaker will then trip open, and the generator shall continue to run unloaded for a preset cool down period followed by automatic shutdown. The RTU shall also provide outputs for generator set alarm & status functions to provide for remote monitoring at the central control location.

1.7.2.1 Programmable Load Control

In the case of existing system failure, then a new system shall be installed where the sequence of operation shall be as described below:

The Power Plant Programmable Load Control (PLC) or approved equal shall be the primary device for automatically starting and stopping each module in response to base load variations and for managing cold load (initial) startup after outages and synchronized operation of the plant with the utility (should this requirement be needed). The PLC shall be designed to show status of the reclosers located in the existing synchronizing control panel.

The interface to the existing control panel shall be such to allow the PLC to operate and monitor the status of each of the four distribution circuit reclosers feeding the base loads. Future energy projects will require monitoring of a Utility company tie switch through the existing 120 Volt control circuits. The PLC shall have the following general operation modes:

1. Cold or Initial Start, no power on base load bus: The logic, upon a command to start either manually or from a remotely generated command through an I/O contact via a communication interface, start the first module to obtain control power, leaving the generator breaker open. Upon receiving a verifying input signal from the first module indicating stable operation, the PLC shall then shall initiate a momentary contact closure to command each of the four load reclosers and the base utility switch to open. After a verifying input signal (from the remote device A/B contact) indicating the reclosers and utility switch are opened, the PLC shall command the first generator breaker to close to the bus. The PLC shall in turn command the next two modules to start, and automatically synchronize to the first on the load bus. Upon receiving a signal from each module of a successful start and close along with independent input verifying availability of bus voltage at the correct level, the PLC shall then command the first load recloser to close the first base distribution circuit to the bus. After a sufficient time delay and after verifying input from the device A/B contact indicating desired operation, the PLC shall close the next three load reclosers in turn in like manner. Should a recloser be manually turned off at the control panel, the PLC shall ignore its condition and not attempt to close it by remote means on startup. The PLC shall then monitor the load and stop or start the modules to serve the load with a 25% minimum spare capacity on line at all times. One module may be run under light load conditions such as nights and weekends, however two modules will be run at all times during normal duty hours as directed by the COR.

2. Overload or Fault on system bus: The PLC shall monitor bus load and attempt to maintain bus voltage and frequency by starting and stopping modules to satisfy load. Short time faults on the distribution system and overloads shall not initiate shutdown of any module unless the condition persists beyond 3 seconds. The line reclosers shall not be set for a time longer than this time. The PLC shall monitor the recloser status after the initial startup and not command any recloser to close after a trip or after it has been manually opened at the control panel. A system fault which causes the bus voltage or frequency to decay beyond preset limits for longer than 3 seconds shall initiate an immediate shutdown by the PLC which shall command the Generator Breakers to open, and the generator shutdown sequence to be initiated. The system shall remain shut down until manually restarted as in #1 above.

3. Loss of utility: The loss of utility starts engine start delay timer in the PLC. If this timer expires, than the following sequence occurs: 1. The closed utility breaker opens. All 4 circuit reclosers and primary PV switch open 2. The generators start. 3. The first generator to reach 90% of rated voltage and frequency closes onto the bus. The paralleling logic shall prevent both generators from closing onto the bus simultaneously. 4.

The other generators synchronizes to the bus. When synchronized, their circuit breakers closes. 5. With all called up generators on-line, the reclosers begin closing in succession. 6. If the generator management control is in AUTO, the system will monitor the power demand of the load, if the load demand is below the setpoints set by the operator, the system will automatically take a generator off-line. If the load should increase, the system will automatically place the generator back on-line. 7. If the system becomes overloaded or if a generator fails, the system will close a set of normally open dry contacts signaling downstream load to shed.
