摘　　要：为了解决分布式发电系统中存在的孤岛检测问题,提出了一种新型复合式孤岛检测方法。该方法通过改变扰动电流波形对传统的AFD检测方法进行改进,并结合传统被动式孤岛检测方法判定孤岛现象的发生。结合IEEE.Std.2000-929/UL1741标准中的技术规范,利用Matlab/Simulink对新方法进行了仿真验证。仿真结果显示,该方法既能快速、准确地检测出孤岛现象,又把对电网电能质量的影响降到最小。In order to solve the islanding detection problem in the distributed generation systems, a new islanding detection al-gorithm is proposed based on summarizing the shortcoming of traditional islanding detection methods. The new algorithm combining with the advantages of traditional passive islanding detection methods and improved AFD method, the islanding identification is real-ized by organic combiuation of the two methods. Simulation are developed to vahdate the proposed method. The experimental results verify the good performance of the proposed method.
