| 摘 要： | 分析了光伏并网发电系统的工作原理及其孤岛效应现象，提出了主动式孤岛效应识别方法：主动频率偏移法。在MATLAB/SIMULINK下分别进行了系统的建模与仿真，并进行了实验研究。结果表明：实验与仿真结果吻合，输出并网电流波形良好，和电网电压同频同相，基本上可以在100ms内有效地检测出系统的孤岛效应。

| Abstract: | The operational principles of photovoltaic generation system and the islanding of grid-connected generation system were analyzed, and the active identification method of islanding: active frequency drift method was proposed. The simulation model of system was established, and the experiment was researched .The results prove: experiment is almost the same as the simulation, and the output wave of grid-connected current is better, and has the same frequency and phase as utility grid, and the islanding can be detected effectively within 100 milliseconds basically. |
