摘要

利用EMTP软件模拟了相间电容对中性点接地系统空母线上铁磁谐振的影响。结果表明

相间电容不仅使谐振的概率增大

而且使谐振电压的幅值增加。因此在分析铁磁谐振现象时不能忽略相间电容。另外

在工程分析中

可取相间电容相等。

Abstract

The capacitive coupling between busbars has an effect on ferroresonance occurring on neutral-grounded systems. In this paper

the effect is studied by software EMTP. Results show that the capacitive coupling not only increases the possibility of ferroresonance

but also raises the amplitude of the resonant voltage. It is advised that capacitive coupling may be not ignored when ferroresonance is concerned. In addition

the coupling capacitances among three phases could be taken to be equal in practice.
