Seventeen Regional Map Based on the Voltage and Reactive Power Control Method and its Application

This paper presents a substation voltage and reactive power control methods,including:1) to divide the seventh regional maps of voltage and reactive power passing rate and the corresponding voltage and reactive power control strategy for optimal control of a method.2) Set the measured variables U,Q sampling data time,collecting a measurement of n variables,and the gross error of each measured variable removed.3) The seventh priority mode to control the regional map is divided into only consider the voltage,only consider the reactive power,Priority voltage and reactive power priority,considering the five patterns.Corresponding to each priority mode combined with the corresponding area of the corresponding control strategy expert knowledge base.The collected real-time voltage U,real-time reactive power Q determine the current system in which the seventh position of the regional map specific regions,with priority mode control strategy based on expert knowledge and then get the current control strategy is to satisfy the control condition stall regulation transformer or capacitor switching export operation,to achieve optimal control of voltage and reactive power.The application of the method can effectively reduce the loss of existing equipment,increase the voltage passing rate,reduce the burden on the staff,reactive power and voltage of substation automation,the system voltage and reactive power to achieve optimal economic operation.
