| 摘 要： | 分析了光伏并网发电逆变系统出现孤岛状况的条件和负面效应,对传统的孤岛检测方法进行了比较.针对现有孤岛检测方法中的"检测盲点"问题,提出一种用无功补偿技术进行孤岛检测的方法.分析结果表明,该方法具有检测无盲点、响应速度快以及对发电系统有功输出无影响的特点.

| Abstract: | The producing conditions and effects of islanding in grid-connected PV system are studied. There is NDZ problem in the conventional methods of islanding detecting. A new method using RPC is presented in this paper to resolve the problem. This method has the advantages of no NDZ, high response speed and no influence on active power output of system. The simulation results validate the feasibility of this method. |
