| 摘 要： | 在PSCAD上对实际500kV变电站谐振进行了仿真,并运用MATLAB软件对仿真得到的谐波数据进行了波形分析。模拟了不同风电厂功率及不同串联补偿装置数值和数量条件下变电站发生谐振的情况,分析了仿真谐振波形和实际谐振波形,找到谐振原因,并据此提出了抑制谐振的方法,并在实际变电站运行中得到验证。

| Abstract: | An actual 500kV substation ferro-resonance on PSCAD simulation is performed,and the harmonic analysis of the simulation is carried out by using MATLAB software.The differ ent wind farm power and the different quantity and values of series compensation are simulated.The simulation waveform and the actual ferro-resonance waveform are analyzed,and the reasons of the ferro-resonance is found,according to which a method to suppress ferro-resonance is proposed.The method is validated in the actual substation operation. |
