Abstract Voltage stability has become common potential threat of receiving-end load centre power grid such as Beijing, Shanghai, Guangzhou, ect. In order to analysis voltage stability of receiving-end grid, take Guangzhou power grid as an example, through simulation analysis, it reveals two different degree transient voltage instability mode of receiving-end grid: the system transient voltage instability and local transient voltage instability. In order to improve the reliability of the load model, this paper puts forward a method to establish real-time classification load model. Take a actual single phase short circuit fault in guangzhou power grid as an example, the simulation results show that the proposed modeling method is effective and feasible.

Key words： voltage stability real-time classification load model real-time classified load characteristics analysis system
