摘要： The inventive method comprises the steps of introducing a reactive current reference square wave, detecting load voltage changes at every change in the reactive current reverence wave, and determining whether the detected load voltage changes exceed a predefined islanding detection threshold value, indicating a loss of mains and an islanding operation of the power generator. With the inventive loss of mains detection, islanding can be detected within a shortest period of time, even if the local islands active and reactive load matches exactly the distributed generators active and reactive power generation. So even without a sudden voltage change, unintentional islanding can immediately be detected and control electronics can safely turn of the distributed power generator.
摘要翻译：本发明的方法包括以下步骤：引入无功电流参考方波，检测无功电流回波中的每个变化时的负载电压变化，以及确定检测到的负载电压变化是否超过预定义的孤岛检测阈值，指示电源损耗和发电机的孤岛作战。由于本发明的电力检测损失，即使局部岛有功和无功负载恰好匹配分布式发电机的有功和无功发电，也可以在最短的时间内检测孤岛。所以即使没有突然的电压变化，也可以立即检测到无意的孤岛，并且控制电子装置可以安全地转动分布式发电机。
