Distribution Automation in Case of Tie Bus between Two Feeders at Donekoy Substation in Laos

Abstract:

This paper proposesthe coordination between recloserandfuse link, reclosertorecloser, and recloserwith over current relay in tie feeder 1, 2ofDonekoy substationin Laos PDR.Disilent power factory software is used for simulation toimprove the operation of protective devicesand analyze the operating timein the distribution system.The operating coordination of recloser, fuse and overcurrent relayis improved. Resetting their functionality to limit the fault,the coordinating power aimsto reduce the problems of outages on distribution and also makes the system reliability.In case of maintenance circuit breaker, the 22 kV - tie bus applies to loads feeder 2 to ensure the stability power to appliances load of customers.Therecloser3 was installed on feeder 2 to protect the faults,and coordinates with recloser2 while the short circuit occursat fault2.
