摘要
平行双回线中一回线路发生故障,对非故障线路保护也会产生一定影响,如功率倒向问题。就一起因功率导向引起的线路保护误动事件进行分析,并提出改进措施,对落实电力系统继电保护及安全自动装置反事故措施具有良好的借鉴作用。
In the double-circuit transmission lines , faults occurred in one circuit will affect the line protection in another circuit.Power converse is a typical example .A malfunction of line protection action due to power converse is analyzed . Improvement recommendations are then proposed to ensure the correct actions of the relay protection and safety automatic protection devices .
