1) fundamental frequency cycle
工频周期
1.
When a single-phase fault occurs on shunt reactor compensated EHV transmission lines,the elements,which compose the recovery voltage of the opened phase after the breaker tripping,include one more resonant component under transient faults than under permanent faults,so the fault nature can be distinguished by making an integral of the recovery voltage during a fundamental frequency cycle.
带有并联电抗器的超高压输电线路发生单相故障两端跳闸后,断开相恢复电压的组成成分在瞬时性故障时比永久性故障时多了一项自由分量,因此通过对断开相恢复电压在一个工频周期内进行积分就可以区分两种不同性质的故障。
2) frequency notch period
陷频周期
3) complex frequency period
复频周期
4) multifrequency period
多频周期
6) line period
行频周期
