摘　　要：为了对光伏逆变器性能参数进行准确有效的测试,需要搭建高性能的测试平台。本文对基于三相高频PWM整流器的光伏阵列模拟器作为试验电源的光伏逆变器综合性能测试平台进行系统仿真,验证了该方案的合理性和可行性,且有效解决了大容量和网侧谐波和无功污染的问题。同时,本文还对光伏逆变器的一些关键性能参数,如光伏逆变器效率、最大功率点跟踪性能、反孤岛保护功能、逆变器输出波形质量等,进行了分析和研究,并提出了测试方案,为进一步的测试工作打下了基础。In order to test the comprehensive performance of PV inverters accurately and efficiently,a high performance test platform should be set up.This paper proposes a novel scheme;power of the test platform is a PV array simulator which is based on three phase high frequency PWM rectifier.A simulation of this scheme is done,validating its rationality and feasibility,and solves other problems such as large capacity,harmonics and reactive power pollution to the grid.Furthermore,this paper analyses and researches several key parameters of the PV inverter,such as conversion efficiency,maxima power point tracking capability,islanding prevention function,output wave quality,and so on.It also proposes test scheme and lays a foundation for farther test work.
