浅谈电力系统谐振过电压

Talking about the Resonance Overvoltage of Power System

本文详细分析电力系统线性谐振和参数谐振,以及谐振过电压的危害,在电力系统运行中,为了限制和消除这类有危害的过电压,提出可以采用的方法。电力系统运行中,因为有电感、电容的存在,加之不同情况下对设备的运行方式和状态的改变,导致谐振和过电压,本文探讨了实际运行中产生的多种谐振过电压以及危害较大、产生频率较高的铁磁谐振,并结合工作实例进行分析,且提出了相应的改善措施。我们研究谐振的目的就是要科学地利用谐振的特征,与此同时又要预防它在我们生活和工作中带来的危害。

In this paper,the linear resonance and parametric resonance of power system and the harm of resonance overvoltage are analyzed in detail.In the operation of power system,in order to limit and eliminate such harmful overvoltage,a method can be proposed.In the operation of the power system,because of the existence of inductance,capacitance,and changes in the operation mode and state of the device under different conditions,resulting in resonance and overvoltage,this paper discusses the various resonant overvoltages and hazards generated in actual operation.Large,high-frequency ferromagnetic resonance is generated,and the corresponding improvement measures are proposed through the combination of working examples.The purpose of our study of resonance is to scientifically exploit the characteristics of resonance,while at the same time preventing the harm it brings in our lives and work.
