摘要
结合不同原理构成的相间距离保护Ⅲ段在线路过负荷时是否会误动进行了分析,并从继电保护的选择性方面对相间距离保护Ⅲ段的动作原理提出了要求及建议,确保了继电保护整定计算的正确性和保护动作的选择性。
It is analyzed whether the miss operation of interphase distance protection of stage Ⅲ will occur during line overload combining with different principles.The requirements and suggestions are proposed for the operating principle of interphase distance protection of stage Ⅲ in view of the selectivity of relay protection,which can guarantee the correctness of setting and calculation of relay protection and the selectivity of protection actions.
