摘　　要：针对常规解列装置的配合存在误动和拒动的问题,以东北电网2013年500 kV线路相间短路故障为研究对象,根据DBSCAN算法原理,提出了基于同调分群的解列配置及配合方法。结果表明:相对于常规解列方法,基于同调分群配置的解列及配合方法可有效避免电网中布置多套解列装置后,各装置相互间出现的异常动作。Aiming at the problems of maloperation and refusing action in the coordination of the conventional splitting devices, taking the phase- to- phase short- circuit fault of 500 kV power transmission line of Northeast China power grid in 2013 as the research objects, according to according to the DBSCAN method principle, puts forward the method of islanding configuration and coordination based on coherency identification. The result shows that: compared with conventional splitting measures, the islanding configuration and coordination measures based on coherency identification can effectively avoid abnormal action between the devices after multiple splitting devices are installed in power grid
