摘要：
With the development of transmission of electricity from the west to the east in south China power grid, the transient voltage stability problem emerges in received power grid gradually. This paper discusses the transient voltage stability mechanism and influence factor. The result shows that reactive power requirements of AC lines and DC inverter will deteriorate voltage stability in the dynamic process, and the local areas load unstable will cause voltage collapse in the whole system finally. The corresponding control measures are also analyzed, and dynamic reactive compensation can restrain voltage collapse caused by induction motor load.
