摘要
本文提出了一种电力系统并联铁磁谐振计算机仿真的新方法,能够方便准确地计算出谐振前后三相电流、电压、磁通以及中性点电压的瞬时值,并能够得到整个变化过程的波形图。从而能立即判断系统是否发生了谐振以及谐振频率等。
A new method for digital simulation of the ferroresonance in the neutral ungrounded power system is presented. The instantaneous values of voltages, currents and. quantities of flux on three phases, and the nentral voltages before and after the ferroresonance are calculated conveniently and accurately. The wave curves for the whole variation process are also obtained. Based on these wave curves, the ferroresonance and its frequency are found out immediately.
