1·Traditional passive and active islanding detection methods are discussed in the paper.
分析介绍了已有的主动和被动式孤岛检测方法。
2·Not only the of maximum power point tracking and islanding protecting techniques, but also the technique for inverter to connected with grid are discussed in detail.
通过对光伏并网逆变器最大功率点跟踪、孤岛效应和并网控制等问题的分析，提出了具体的解决方案。
3·Moreover, the islanding phenomenon grid?connected run mode brings has hazards to load, inverter and life safety.
另外，并网运行模式下所带来的孤岛现象，对负载、光伏逆变电源和人生安全构成了危害；
4·So, all electric power network grid should have the ability of detecting islanding status and stopping the run mode of grid connect.
所以光伏并网发电系统都应具有检测出孤岛状态并停止并网运行的能力。
5·In photovoltaic grid-connected generation systems, whether the condition of islanding can be detected effectively and timely or not is of great significant for the entire grid-connected system.
在太阳能并网发电系统中，如何有效、及时地检测孤岛效应对整个并网系统具有重要的意义。
