Simulation of substation voltage and reactive control based on fuzzy theory

The fuzzy control theory is applied on reactive voltage control. With voltage and reactive power deviation as its input, and the transformer tap and capacitor switching as its output, MATLAB Fuzzy Logic Toolbox are used to form the fuzzy inference system. NanYi substation in JiangXi is an example. In the TH2100 software simulation, the results show that the control system is stable and reliable, the control effect is good.
