摘要
基于一起谐振过电流的案例,本文首先分析了电力电容器在运行中与系统发生谐振的两种不同机理,并提出了相应的解决思路。然后,通过Matlab Simulink软件建立系统模型,对2种谐振类型进行了仿真,并验证了所提出解决方案的有效性。最后,根据现场投运试验的结果,得出导致本次谐振的原因是并联谐振的结论。最终,通过调整电容器组运行方式,成功规避了谐振问题。
In this paper,two types of different mechanisms of resonance with system during operation of power capacitor is analyzed firstly based on resonance over current case and corresponding solutions are proposed. Then, the system model is established by way of Matlab Simulink software to simulate two types of resonances and verify the efficiency of the proposed solution. Finally,the conclusion is that the reason for this resonance is due to parallel resonance in accordance with the result of site test. And the resonance issue is avoided successfully by way of adjusting operation mode of capacitor bank.
