中文摘要:

辐照度变化引起的并网光伏逆变器功率波动可能会引起并网点闪变，本文首先分析了闪变与并网阻抗大小、阻抗角度和功率波动大小的关系，并针对目前广泛使用的500kW光伏逆变器开展了重载、轻载运行与启停机测试。基于Matlab/Simulink软件搭建了虚拟电网模型和数字闪变测试仪模型，分析了不同电网条件下并网光伏逆变器重载、轻载运行和启停机状态的闪变测试结果。

英文摘要:

Power fluctuation caused by irradiance changes may cause the flicker at the grid-connected point. The relationship between the flicker and grid impedance, the power change amount is analysed. And the flicker is tested on a 500kW photovoltaic (PV) inverter at different load and switch operation. Based on the vitual gird model and the flickermeter model developed on Matlab/Simulink platform, the flicker test results of switching operation and continues operation are analysed.
