随着新能源发电技术的普及应用及公众节能环保意识的提高,太阳能建筑一体化光伏系统(building integrated photovoltaic,BIPV)得到了越来越多的应用。针对一种城市住宅小区屋顶太阳能并网光伏发电系统的方案,在孤岛检测方面提出一种基于传统被动式孤岛检测方法和主动电流幅值偏移法的复合检测方法。实践表明,此方法在电网失电时,能迅速检测出孤岛效应。
隨著新能源髮電技術的普及應用及公衆節能環保意識的提高,太暘能建築一體化光伏繫統(building integrated photovoltaic,BIPV)得到瞭越來越多的應用。針對一種城市住宅小區屋頂太暘能併網光伏髮電繫統的方案,在孤島檢測方麵提齣一種基于傳統被動式孤島檢測方法和主動電流幅值偏移法的複閤檢測方法。實踐錶明,此方法在電網失電時,能迅速檢測齣孤島效應。

With the popularization and application of new energy generation technologies, solar building integrated photovoltaic (BIPV) systems has been increasingly used. Aiming at a grid-connected photovoltaic rooftop solar system in urban residential scenarios, the paper proposed a method based on a traditional passive islanding detection method and an active current amplitude offset method. Practice shows that this method can rapidly detect islanding effect when the power grid is shut down.
