摘　　要：为分析高渗透率情况下的分布式电源接入规模较大的配电网的谐波特性,介绍光伏发电并网系统和风力发电并网系统的数学模型和仿真模型,在PSCAD/EMTDC中将多组光伏电池和风力发电机接入IEEE 30节点标准测试系统进行仿真。测量相应的节点电压和支路电流,对测量的节点电压和支路电流进行快速傅里叶变换(fast Fourier transformation,FFT)分析,得出了影响谐波电压畸变率的因素和影响谐波电流畸变率的因素。To analyze the harmonic characteristics of distributed generation of high penetration connected to the large distribution network, the mathematical model and simulation model of grid-connected photovoltaic system and grid-connected wind power system are introduced and several photovoltaic cells and wind turbines are taken into the IEEE 30 bus test system to be simulated in PSCAD/EMTDC. Through fast Fourier transformation（FFT） analysis of node voltage and branch current which are measured, the factors which affect total harmonic distortion of voltage and current are found.
