摘　　要：介绍了光伏发电并网系统对电网产生的影响,并以孤岛效应作为研究对象,对目前比较常见的被动式和主动式孤岛检测方法进行了分析比较。在实际应用中,结合各方法的优缺点,选择两种或多种方法组合使用,大大提高了孤岛检测的效果,是未来孤岛检测技术发展的主流之一。Introduction was made to the impact of photovoltaic grid-connected system on the grid and the islanding effect was picked as the research topic. Analysis was made to some commonly used passive and active methods at present. As each method has its own characteristics, one or more detection methods should be rationally selected in practice according to actual situation, in which two or more different detection methods could be used in combination to improve islanding detection results greatly. This combination method will become one mainstream of development of the islanding detection technologies in the future.
