After a time delay (adjustable from the touchscreen), all generator sets automatically and independently start, accelerate to rated frequency, and build up to rated voltage. The "First Start" system monitors this process, and on finding a generator set at 90% of rated voltage and frequency, automatically disables the other units from closing to the bus, and closes the first ready unit to the bus. At this time the utility main breaker is opened, non-essential loads are shed, and the generator main breaker closes connecting the generator set to the system bus. The priority (Load Add) controls prevent overloading of the system bus by providing inhibit signals to prevent operation of selected loads on the system until sufficient generating capacity is available on the bus, or until the priority override switch 'on the touchscreen control is actuated. There are four double-ended unit substations (USS #1,2,3,and 4)and two influent pump feeders in the system that shall be shed and added in the following priority (highest to lowest): Priority 1 - USS #1 (This load shall not be shed except in an emergency); Priority 2 - Raw Sewage Pumps, IV,lC,2V,2C; Priority 3 - USS #2 Right end/USS 3 Right end; Priority 4 - USS #2 Left end/USS 3 Left end; Priority 5 - USS #4 Left end; and Priority 6 - USS #4 Right end. Note the following statements for the operation of features: ~Load Add" and ~Load Shed" Load Add Feature: The load add feature will have one (1) level for each generator set. Each additional load will be added after a preset time delay. Each feeder breaker will have a dedicated relay. The highest load add level is "1" so that it will be added first. Relays are user programmable from the touchscreen to allow each relay to be individually assigned to any load add level available. The system will have seven load add levels. It is pennissible to assign multiple relays to an individual load add level. This pennits re-assigning load add levels to all transfer switches or circuit breakers connected to the relay without re-wiring. «5 Load Shed Feature: The load shed featur '11 have one (1) level established for each generator set (levels O,I,2,...,etc./relays 1,2,3,...,etc . Each additional load will be shed after a preset time delay. The highest load shed level is " so that it will be shed first. The lowest load shed level is "0" and it will never be shed. Relays are user programmable :&om the touchscreen to allow each relay to be individually assigned to any load shed level. The system will have seven load shed levels. It is permissible to assign multiple relays to an individua1load shed level. This pennits re- assigning load shed levels to all transfer switches or circuit breakers connected to the relay without re- wlnng. After the first unit is('clos~d to the bus, the control of the remaining units i~' switched to the synchronizer in each generator paralleling control, which causes the generator set to synchronize.with the system bus, and then close to it at the proper time. . . As each unit closes to the bus, the unit assumes its proportional share of the total load on the bus. If a generator set fails to start, after the overcrank time delay the unit will be shut down, and an alarm will sound. If a unit fails to synchronize, after a preset time delay an alarm will sound, but the unit will continue to attempt to synchronize until signaled to stop by manual operation of the control switches on the generator set. 1 Cummins anan Apríl28.2004 ,¡, Oshkosh WTP PowerCommand Digital Paralleling Medium Voltage Applications - Utility Parallel Sequence of Operations Revision: A Date 4/2/04 In the event that one generator set fails when the system is supplying emergency power, the failed generator set will be taken off line by opening the pertinent generator breaker. With one or more generator sets off line, the priority control will prevent the lowest priority loads from being added to the system without manual intervention. The priority override controls on the touchscreen may be used by an operator to manually add low priority loads to the bus, if he determines that generator set capacity is available to serve the loads. Bus overload monitoring shall protect the first priority loads in the event that the bus is inadvertently overloaded due to operator error. If a bus overload occurs for any reason, a load shed signal will be generated to initiate load shedding in the system. If the bus does not return to proper frequency within a predetermined period of time, additional load shed signals will be generated. Load Demand Mode: When the system is running in the emergency mode with the ~load demandw switch on the touchscreen in the ~onW position, controls shall continuously monitor the total load on the bus. If the total load on the bus falls below preset limits for a period of 15 minutes [time delay is adjustable from the touchscreen], the controller will automatically shut down generator sets in an operator predetermined order, until the minimum number of generator sets required to operate the load remain on the bus. The purpose of this function is to allow the generator sets to operate closer to rated capacity decreasing fuel consumption and reducing component wear on the system. On sensing that the available bus capacity is being approached, the standby unit will automatically be restarted (in the reverse order of which they were shut down) and paralleled with the bus to assume its proportional share of system load. Return of Utility Power: When the utility power supply has recovered to proper voltage conditions and all system start signals are removed, the system enables a time delay [time delay is adjustable from the touchscreen] before initiating the retransfer sequence. On the completion of the retransfer time delay [time delay can be bypassed from the touchscreen], the system will begin a retransfer process in either open or closed transition mode, as selected by the operator. If running in the closed transition mode, the system shall synchronize the generator bus to the utility, close 52-UM, ramp down load on the gensets to a minimum value, then open 52-GM. The generator set paralleling breakers will open and the generator sets will then run unloaded for a cooldown period and shut down. If the operator has selected open transition mode, 52-GM will open and 52-UM will close. The generator set paralleling breakers will open and the generator sets will then run unloaded for a cooldown period and shut down. If a system start signal is received during the cooldown period, one generator set shall immediately close to the emergency bus and all other units sha¡l synchronize to it, as described in ~Utility Power Failurew above. Test Mode (open transition): Operation of the test switch will simulate a power failure in the system, causing the genset to start, and the system to transfer as described in "Loss of Normal Power" above. Returning the test switch to normal will cause the system to return to normal power as described in "Return of Normal Power (open transition)" above. Test Mode (closed transition): Operation of the test switch will simulate a power failure in the system, causing the genset to start, and the system to transfer as described in "Loss of Normal Power" above. Returning the test switch to normal will cause the system to return to normal power as described in "Return of Normal Power". Once all generator sets are on the emergency bus (52-Gs are closed), the system will synchronize across and close breaker 52-GM. The bus will then ramp up to assume the load. When the load supplied by the utility reaches a minimum level 52-UM is opened. "- ,.' 2 Cummins Onan April 28, 2004 t-' Oshkosh WTP PowerCommand Digital Paralleling Medium Voltage Applications - Utility Parallel Sequence of Operations Revision: A Date 4/2/04 , .. When the system is running in the test mode with load demand enabled, controls shall continuously monitor the total load on the bus. If the total load on the bus falls below preset limits for a period of 15 minutes [time delay is adjustable from the touchscreen], the controller will automatically shut down one generator set. On sensing that the available bus capacity is being approached, the standby unit will automatically be restarted and paralleled with the bus to assume its proportional share of system load. Returning the test switch to "Normal" position will cause the system to return to normal power as described in "Return of Normal Power (closed transition)" above. Test Mode (Without Load): The operator from the touchscreen can put the system into a test without load mode. In this mode of operation the generator sets shall start, build up to rated speed and voltage, synchronize and close to the generator bus, but system loads shall not automatically transfer to the generator system. Automatic Operation - Peak Shave Mode: Durinq the peak shave mode. Load Demand mode will be disabled. The peak shave mode may be selected via dry contact or locally from the Operator Interface Touchscreen. On receipt of this signal, the gensets start and the system connects to the bus as described in "Loss of Normal Power" above. Tr king MOde Se ected: Once all generator sets are on the emergency bus (52-Gs are losed), t system will synchronize across and close breaker 52-GM. The Mast Control PLC will calculate the required generator KW level using a trans ucer in ut from the switchgear. The bus will then ramp up to assume the load a ove t e peak shave KW setting (set on the operator touchscreen). This will aI ow e Utility to maintain a constant load while the generator system adjusts to upply the load -peaks". ode Selected: Once all generator sets are on the emergency bus (52-Gs ), the system will synchronize across and close breaker 52-G. The bus amp up to assume the load up to the base load setting on each et(set on the generator set setup screen). If the building load is is setting, excess power will be exported to the utility. The 32 he SEL relay is disabled in this mode. On re eipt 0 a peak shave shutdown signal, the generator bus will gradually ramp down 0 a pr set level, and 52-G will open. The generator set paralleling bre ers wil open and the generator sets will then run unloaded for a cooldown per'od and sh t down. I there is a power failure while in the Peak Shave Mode, utility protective r lay will trip 52-liM. Tie Breaker: The tie breaker in the distribution gear is normally closed. The tie breakers in USS 1,2,3,and 4 are normally open manually operated. The. distribution gear tie will remain closed unless the operator opens it to maintain one side or the other. The normal operation is to feed each half of USS 1,2,3,and 4 from the distribution gear with the ties in the substations open. If operator opens the tie in the distribution gear for maintenance, they have manual procedures for closing the ties in the substations, opening the tie in the distribution gear, and feeding both halves of the substations from either the utility source or the generator source. 3 Cummins anan April 28, 2004 -------- -, --,-- - ._- u J, ~ '" ~~ ~ ï - ¡¡ ~ I s ~~ ~'-~I:~l - ~ '-rH H . ~ ...-" ~~ r -- -- n n - _h- - -- - - - - ----- ----~'~'~::o2i~~_~_--- ----, ¡ . : , ' , ' , , , , , , , , , , , 1 1 1 , , , , , 5: ~: 8' ",' ¡:!' ~[ ~: .,' ä: , , , , , 1 1 1 1 , , , , I I , I I I , , I L - --- - - - - n - -- - - - -- - - --- -- - -- - -- - - - - -- --- - n_____J L___n - -- --- __n--___-___n ------ _-__n ~~'6D ~ ~~ ' ~~ ~~ ~ ~! -..----- -_oj : , I i ~¡['È ~ YT;T;l : " -" . liUü " ~ '1 ~ -jH 8~ >~ ä i i ,,; " ~I ~i <" . ~~g %~ ~~§ >--r---<~ .:... o"';r. , .$ Ji.,.2 ; T'~ L .-..-"- - ,- - _.._.
