Automatic Control Method of Circuit Breaker Based on Integrated Power Sup-ply System of Substation
In order to improve circuit breaker opening and closing performance and intelligent operation level,the au-tomatic control method of circuit breaker based on integrated power supply system of substation is studied.Analyze circuit breaker motion characteristics.Design circuit breaker automation controller by digital double closed loop method.The outer loop uses a single neuron adaptive PID control algorithm to adjust the speed of the circuit breaker moving contact and get the reference voltage.By comparing and analyzing the actual voltage value and the reference voltage value,combined with the fuzzy PI control algorithm,the voltage control quantity is obtained,and the motion speed of the circuit breaker contact is controlled to realize the automatic control of the circuit breaker.Ex-perimental results show that this method can effectively control the speed of circuit breaker contacts for both opening and closing operation.Under different capacitors,the fluctuation amplitude of the jumping signal points of the moving contacts automatically controlled by this method is small.
