摘　　要：在电力市场条件下,区域子系统运行具有相对的独立性、系统数据具有一定的不透明性。文章研究了与市场条件相适应的区域互联电力系统的同调发电机识别问题,基于弱耦合算法提出了一种子系统内同调机群的分布式识别方法,在相邻区域子系统间通过交换少量的边界母线信息可形成子系统状态矩阵,实现对子系统内同调机群的识别。通过50机145节点系统的算例验证了该方法的有效性。In the electricity market environment, the operation of areal subsystems is comparatively independent and the parameters of a subsystem are relatively nontransparent to other subsystems. The authors research the identification of coherent generators in interconnected areal power systems which is in accordance with market condition, and based on the weak-coupling algorithm a distributed identification method for coherent generators within the subsystem is presented. Using the presented method, by means of exchanging a small amount of boundary busbar information between adjacent areal subsystems the subsystem state matrix can be generated and the coherent generators within the subsystem can be identified. The calculation results of 50-generator 145-bus system verified the effectiveness of the presented method.
