摘　　要：本文介绍了一种新的在线稳定计算的网络等值方法,这种方法将系统按同调群以暂态电抗后的节点来等值,保持了对单个电机暂态行为的描述,具有精度高应用方便的优点。本文指出了常用的保留发电机端节点同调网络等值算法所存在的问题,经过推导提出了改进意见。This paper presents a simple but very accurate coherency based network equivalent method. Bus admittance matrix is interconnecting the transient internal voltages. It is not necessary for each coherent group to be replaced by a fictitious machine and aggregation or averaging procedures for machine parameters are not required. The method facilitates the reduction of transient stability study. The most ordinary method for coherency dynamic network equivalent is applied to the generator terminals. Some mistakes or carelessness was found. Corrections and discussions are also given in this paper.
