2 New Complete Systems
The retrofit project replacing the old existing distribution panel boards with a new system.
The delivery included one Synchronization switch gear of 8 Detroit diesel generators each 1MW/380V/60Hz QGCB 1600A and two Feeders 1600A the dead bus (common busbar) assembled with 8000 Amps capacity equipped with InteliSysNT + InteliVision 8 + pControl SCADA, one Synchronization Control Cabinet of 3 diesel generators with InteliSysNT + IS-Display, five 2500Amps Automatic Transfer Switches panels with InteliMainsNT, three Bus Coupling Panels of two City Transformers (PLC Control), one panel on dead bus with InteliProtec.
Sequence of operation:
First system - If one, two or all of the ATS(s) experience AMF, a command from the synch system is sent to start over, synchronize and get ready to supply the failed ATS(s). The mains breaker will be tripped and the ATS bus breaker will close to the load providing the power supply from the standby synch switchgear. This will start a load sharing process and start or stop the number of working gen-sets upon load demand. When the failed ATS(s) are restored, the ATS will change over from standby synch power supply back to mains supply. The gen-sets will be commanded by the ATS controllers to cool and shut down when required.
Second system - One Mains is prior feeding the load and 2nd Mains is standby if prior mains get fail the standby will feed the load and if the 2nd also get fail, then the standby power generation will start run will feed the load and if the 2nd also get fail, then the standby power generation will start run and synch on dead bus after what the BTB will close feeding the load from standby power. If one of Mains restored, the BTB will open and the Restored Mains will feed the load and the Standby Power will cool down and stop.
