摘　　要：论文提出一种光伏发电系统低电压穿越现场测试新方法。该方法利用测试现场已有的光伏发电设备构成模拟电网产生电压跌落故障,对被测光伏发电系统进行低电压穿越测试。利用MATLAB/SIMULINK对500k W光伏发电系统组成的光伏电站进行了建模与仿真,仿真结果验证了该方法的可行性。与现有技术相比,现场测试新方法具有实现简单、测试成本低、测试条件灵活可设、测试过程不影响电网安全运行等优点。This paper presents an on-site testing method for PV generation system.The method makes use of the already installed PV generation systems to emulate the grid and produce a given fault for the system under test.Simulation study was carried out for a typical500kW PV generation system and the results validate the feasibility and effectiveness of the method.Comparing to the conventional techniques,the new method has many advantages such as simple,cost-effective,flexible and safe.
