摘　　要： 针对某变电站电弧炉、轧机、电气化铁道等非线性负荷产生的谐波问题,结合该变电站的实际运行工况,利用电力系统仿真分析软件ETAP进行谐波分析,给出一种符合该变电站频率特性要求的无源滤波方法.首先在ETAP下建立该变电站的运行模型,然后仿真分析其谐波特性,最后利用ETAP软件仿真验证所设计滤波器在基波50Hz以及等值频率偏调±1%情况下的滤波效果,为实际工程的研究提供参考. Due to the harmonic problems caused by the non-linear load of a substation such as arc furnace, rolling mill, electrified railway, and the actual operation condition of the substa- tion,by using ETAP for harmonic analysis, a kind of passive filter method is given to meet the requirements of the substation frequency characteristic.The operation model of the substation is established under ETAP, and then the harmonic characteristics are analyzed by simulation. Finally, the simulation results of ETAP are used to verify the filtering effect of the designed filter at the fundamental 50Hz and the equivalent frequency ±1 %, providing reference to practical engineering.
