摘要
阐述了孤岛效应的发生机理和孤岛发生后对电网的影响,介绍了目前国内外反孤岛方法的研究现状,并对基于单相逆变器的孤岛检测方法进行了分类介绍。分析了主动检测法、被动检测法、混合法的检测原理并对优缺点进行了对比分析,结果说明合理地选用两种或多种方法的混合法能够较好地满足电能质量和检测性能要求。
This paper elaborates on the mechanism and influence of islanding effect,introducing the present research situation of islanding detection,and islanding detection methods mainly for single phase invert are classified. The testing principles of active, passive and hybrid methods are analysied,comparing their advantages and disadvantages,and illustrate that the hybrid method can meet the test requirements better.
