Voltage Reactive Power Optimal Control in Substation Based on Rate of Load Change

Current strategy of voltage reactive power control to substation is based on nine-area figure.It is the basic principle of voltage reactive power control to realizethe qualified voltage,the balanced reactive power,and the operating times as few as possible.This paper aims at the defects which exist in the current voltage reactive power control devices based on nine-area figure,such as the control strategy and the running enacted value.Through the analysis to the regulative mechanism of voltage reactive power control,we find out the regulating reason with high frequency,and put forward the corresponding measures to prevent and control these defects.
