摘要
提出了小电机组侧线路开关采用特殊保护整定原则,这样,可防止当大电源与接有小电源并网运行的线路发生瞬时故障时,因小电源侧的重合闸不能检同期而导致局部电网失电,而造成不必要的供电损失。
Adopting special protection setting principle for line switch in small generating set side is proposed, thus it can avoid unnecessary loss of power supply because the reclosure in small power side cannot calibrate synchronization to cause part of grid losses power during instantaneous fault in the parallel- operated lines with super- power and small generating set.
