摘要
阐述了短期及中长期电压稳定分析方法和建模要求,并针对我国电网仿真分析的现状,指出了电压稳定仿真和建模方面存在的主要问题;结合实际电网的短期及中长期电压稳定仿真计算,分析了短期电压崩溃和中长期电压崩溃过程的事故特征,并对电压失稳机理、暂态电压稳定和中长期电压稳定的评价方法做了进一步的探讨。
The analysis method and modeling requirement for short term and mid/long term voltage stability are expounded. According to the present situation of power system simulation in China the main problems existing in voltage stability simulation and modeling are pointed out; on the basis of short term and mid/long term voltage stability simulation of actual power sysiem, the features of short term voltage collapse and mid/long term voltage collapse are analyzed, and further research on the mechanism of power system voltage instability and the evaluation method for transient voltage stability and mid/long term voltage stability are conducted.
