RESEARCH ON THE CONTROL OF REACTIVE POWER COMPENSATION BASED ON FUZZY REASONING

摘要

With the development of the rural power grids increasing gradually, there are higher requirements needed for its operation in reliability and economy. Reactive compensation using shunt capacitor at both ends of the load, reducing current of lines, and improves the power factor of system. The objective is to reduce losses of line, and improves the quality of voltage and the utilization of electrical equipments. In the switching control of compensation device, using voltage and reactive power these two factors to control, this is the fuzzy control. The range of voltage and reactive power are divided into several regions to determine the membership of each region. Using MATLAB simulation achieves a design method of fuzzy reasoning logic control, and gets an ideal control results.
