摘要
介绍了一种适用于中性点经消弧线圈接地电网的接地保护新原理，给出了基于半波傅氏算法的动作判据算法模型。该判据对接地故障具有很高的选择性能。
A new principle of selective ground-fault protection for the are-suppression coil neutral grounded systems is proposed in this paper. The algorithmic model of the action criterion is presented based on the half-wave Fourier algorithm. This action criterion shows that it is highly selective to the ground fault.
