摘要
Abstract
The phasor measurement unit (PMU) based wide area measurement system (WAMS) provides a new thought and method for online voltage stability prediction.Adopting the π-type of branch model and by use of synchronous phasor measurement data, the voltage stability index based on branch power flow that can be used to HV power network is derived. In the viewpoint of physical meaning, the derived index can be explained as virtual active power margin index IVAM and an improved real-time voltage stability prediction index, which considers the IVAM variation of a certain tie line, is proposed. Calculation results of IEEE 14-bus system and that of a certain provincial power network show that the proposed index is accurate. The proposed improved voltage stability prediction algorithm is accurate and simple in structure, and it is easy to realize its online application.关键词
