Research and Application in Substation Reactive Power Dynamic Compensation Based on Fuzzy Control

On the basis of analysis of the present situation of substation voltage reactive power integrated control and existing problems, this paper puts forward an implementation scheme of substation reactive power fuzzy control system realized based on Siemens PLC. The operation results show that this kind of control idea is feasible and it can effectively reduce the action number of tap and capacitor of on-load tap changer, thereby improving the voltage quality of power supply system.
