摘要
针对大容量10 kV线路继电保护的整定计算中存在的用户故障容易顶跳变电站开关、线路瞬时故障跳闸后重合闸不成功、线路无故障试送线路仍然不成功等特殊问题,通过保护方案的调整,避免上述现象的发生。
There are some especial relay protection problems in 10 kV high-capacity lines,such as the fault of users＇ equipment causing the leapfrog trip of the switch in the substation,the switch reclosing unsuccessfully after the instantaneous fault in the line,and trying to send power unsuccessfully in trouble-free line.The setting calculation of relay protection is improved for 10 kV high-capacity line in order to avoid the above-mentioned phenomenon.
