Current substation voltage and reactive power control scheme existing control is not precise enough, can not completely avoid the capacitor switching back and forth and can not effectively reduce the number of tap adjustments shortcomings, by significantly affecting the voltage and reactive power control of many factors, based on Basic principles of substation voltage and reactive power control Develop a control strategy that can accurately control voltage and reactive power under various system operating modes and reduce the number of adjustments to avoid reciprocating switching of capacitors. The strategy is rigorous, accurate and easy to implement in engineering. Simulation results show the correctness and superiority of the scheme
