An improved reserve power source automatic connection devices plan is proposed after the failure analysis on the change of current &voltage and effect of relay protection to reserve power source automatic connection devices.
为防止一次变全停、保证对用户连续可靠供电,针对66 kV系统双母线单主变压器运行的一次变和有小电源的末端变电所配有备用电源自动切换装置(简称备自投)的2种情况,通过系统故障后电流、电压的变化及继电保护装置动作情况对备自投装置动作影响的分析,提出备自投功能改进方案,即采取改变母差保护闭锁备自投方式及线路跳闸联跳主变一、二次断路器等改进措施,启动备自投,防止上述2种损失负荷情况的发生。
