摘要：【中文】本发明公开了一种配电系统进行不停电倒闸操作的判断方法。本发明利用倒闸瞬间合环点冲击电流与倒闸线路电流保护整定值的配合，当倒闸操作发生时，利用倒闸瞬间合环冲击电流与继电保护整定值相比较来判定能否进行不停电倒闸操作；当冲击电流小于继电保护整定值时，判定为倒闸操作可以进行，当冲击电流大于继电保护整定值时，就判定为不可进行不停电倒闸操作。本发明为配电网不停电倒闸操作能否进行提供判断依据，避免了不可靠的倒闸操作，提高了配电网系统供电可靠性。 【EN】The invention discloses a method for judging the switching operation of a power distribution system without power outage. According to the invention, by utilizing the matching of the switching instant closing point impact current and the switching line current protection setting value, when switching operation occurs, whether the switching operation can be carried out without power failure is judged by comparing the switching instant closing point impact current with the relay protection setting value; when the impact current is smaller than the relay protection setting value, the switching operation is judged to be possible, and when the impact current is larger than the relay protection setting value, the uninterrupted switching operation is judged to be impossible. The method provides a judgment basis for judging whether the power distribution network can be switched off or not without power outage, avoids unreliable switching operation and improves the power supply reliability of a power distribution network system.
