随着分布式发电的发展，越来越多的可再生能源转化成电能输送到电网。按照分布式电源的发电原理可分为同步发电机、感应式发电机和基于逆变器的直流发电设备。目前孤岛检测方法的研究主要集中在单一分布式电源或同一类分布式电源，并没有把检测方法应用到多类别分布式电源并网运行，本文考虑了基于逆变器和同步发电机并网，通过仿真分析了同步发电机对基于逆变器孤岛检测方法的影响，为以后孤岛检测方法的研究提供依据。%With the development of distributed generation, more and more renewable energy is turned into electrical energy and delivered to the power grid. According to the principle of the distributed power generation which includes synchronous generators, induction generators and DC inverter-based power generation equipment, the islanding detection method is mainly concentrated in a single distributed power and the same type of distributed power, but no detection methods are applied to multi-class distributed power network operation. By analyzing the impact of a synchronous generator to method which is based on power inverter islanding detection with the simulation, this paper provides a basic information for islanding detection method when the inverter and the synchronous generator are connected to the grid.
