发电机—变压器组产生谐振原因分析及解决方案

Cause Analysis of Resonance Occurrence in the Generator-Transformer Group and Its Solutions

通过描述山西铝厂自备电厂 6号机— 4号变压器组产生的谐振现象 ,分析了铁磁谐振产生的原因 ,介绍了系统对地容抗 Xc0 和电压互感器励磁电抗 Xm与谐振的关系 。

It analyzes reasons of ferromagnetic resonance occurrence though resonance occurrence in the No.6 generater-No.4 transformer group for the dedicated thermal power plant of Shanxi Aluminum Plant,introduces the relationship of the system to earth capacitive reactance Xco and PT exciting reactance Xm with resonance,and finally it puts forward methods solving this problem.
