| Voltage and power factor are two important parameters of power grid operation,the effective voltage control and reasonable reactive power compensation to improve the power system stability,safety and economic benefits has important significance.Area grid automatic voltage control(AVC)system without power compensation equipment reasonable automatic switching and layering reactive power balance on the spot and voltage stability,because the system is in an application running in period,some of the features and strategies still need to further improve the optimization,to ensure that no compensation of reactive power and voltage regulating more reasonable,the operation of power grid is more economic and safe.In this paper,we first introduce the regional power grid automatic voltage control system and working principle of the control strategy,focuses on the regional power grid automatic voltage control embedded system reform implementation,and studying of UPFC device and regional distributed power supply(wind power,photo voltaic)access,the actual operation of the system case proposed system function,control strategy,security strategy of optimization measures.Through the optimization of the system to further improve the power grid dispatching automation level,and improve the system reactive power voltage equipment control and protection,simplify the operation of personnel maintenance. |
