摘要

铁磁谐振是电力系统中的常见现象

由铁磁谐振引起的过电压和过电流不但会降低电力系统的电能质量

而且会危及系统相关设备的安全运行。笔者应用谐波平衡法对中性点接地系统铁磁谐振电路基频谐振进行分析

找出了该电路的基频谐振区。理论分析和实验证明

该方法能为有效地抑制铁磁谐振提供理论依据

也是电力系统设计的有益参考。

Abstract

Ferroresonance is a common phenomenon in the power system

the overvoltage and overcurrent generated by the ferroresonance will lower the power quality

and endanger the facilities in the power system. In this paper

a harmonic balance algorithm is applied to analyze the fundamental resonance of a typical ferroresonance circuit in a neutral grounded power network. The fundamental resonance region and safety region of the circuit can be found by using the algorithm. the Experimental validation of the algorithm is also investigate in the laboratory. On the base of the harmonic balance theory

ferroresonance can be efficiently avoided

and it is helpful for the power system design.
