TCSC as a transient voltage stabilizing controller Conference Paper uri icon


  • TCSC has been proposed to enhance the voltage stability by changing the reactive power distribution in the power system. Authors have discussed the effect of TCSC on steady state voltage stability and small-signal voltage stability. This paper discusses the TCSC's enhancement on transient voltage stability. A TCSC model that is suitable for transient voltage stability analysis is proposed. This model is tested on a multi-machine system including all the key elements relevant to system voltage performance. The simulation shows that angle-stability-enhancement-like TCSC controllers offer little help for certain transient voltage stability crises. Based on this analysis, a new TCSC controller is proposed and proved to enhance the transient voltage stability.
