摘要
针对大功率光伏逆变器输出滤波电抗器的有功损耗测量目前受自然环境以及技术条件限制尚未达到工业需求的问题,提出了光伏阵列模拟器和光伏逆变器工作过程的互逆性原理并设计了电力电子变流技术改造光伏逆变器,实现光伏阵列模拟器的功能,并得出相对真实的环境数据搭建有功损耗测试平台.此光伏阵列模拟器测试系统可以准确地测试出各项性能和有功损耗量,相较于目前国内的测试方法,该大功率光伏逆变器输出滤波电抗器有功测量更省时、省力、成本较低且能够达到工业的要求.
In order to solve the problem that the active power loss measurement of output filtering reactor of large power photovoltaic(PV)inverter has not been reached the industrial demand due to the limitation of both natural environment and technical conditions,the reciprocity principle for the operating process of PV array simulator and PV inverter was proposed.In addition,the PV inverter was designed with the power electronic converting technique.The function of PV array simulator was realized,and the relatively true environmental data were obtained to establish the active power loss measurement platform.The testing system of PV array simulator can accurately test the various performances and active power loss amount.Compared with the current domestic testing methods,the output filtering reactor of large power PV inverter can perform the active power measurement,which is time-saving,labor-saving and cost effective,and can meet the industrial requirements as well.
