摘要
纵联差动保护两侧的动作行为,在某些故障方式下可能会不一致。通过对某一次110 kV线路区外单相接地转两相接地的发生、发展过程和线路差动保护误动的分析,进一步认识差动保护的抗饱和处理方法。
Actions of the two sides of longitudinal differential protection may be different in some faults, According to a case of fault which the external single ground turns to two-phase ground, its occurrence, development process and line differential protection of the malfunction are analyzed, and the differential protection of the anti-saturation approach is introduced.
