摘　　要：光伏电站在运行时,由于其系统内含有大量电力电子元器件,将会产生谐波,对电力系统造成一定影响,就光伏电站谐波情况,利用电力系统仿真分析软件ETAP进行定量计算分析,结合不同的变电站典型方案,考虑变电站的谐波适应性,给出一种考虑光伏电站谐波问题的接入系统方案推荐。首先在ETAP软件下分别建立变电站模型、升压站模型、光伏电站模型等,然后仿真分析光伏电站PCC点的谐波特性,根据变电站规模的不同,测定出光伏电站PCC点所要求的最小短路电流,为光伏电站接入系统方案提供参考依据。When photovoltaic power plant is running,because of its large number of power components,harmonic are generated,which have a certain impact on the power system.In this paper,the harmonic situation of photovoltaic power plant is analyzed quantita-tively by using ETAP,which is a simulation software of power system.Considering the harmonic adaptability of substation,a scheme recommendation of access system considering the harmonic problem of photovoltaic power station is given.Firstly,the substation model,step-up station model and photovoltaic power station model are established respectively under ETAP software.Then,the harmonic characteristics of PCC point of photovoltaic power station are simulated and analyzed.According to the dif-ferent substation scale,the minimum short circuit current required by PCC point of photovoltaic power station is determined,which provides reference for the access system scheme of photovoltaic power station.
