Development of Intelligent Control System for Motor Mechanism of High Voltage Circuit Breaker
In order to satisfy the demand of the intelligent equipment for the construction of the smart power grids
and to improve the operating performance and running reliability of high-voltage circuit breakers
more and more attention about the motor operating mechanism applied of modern technology is obtained. In this paper
according tothe control characteristics of the vacuum circuit breaker motor operating mechanism
an intelligent control method forthe fuzzy immune PID speed of permanent magnet motor is proposed. In order to realize the intelligent control ofoperating mechanism
a digital servo motor control system based on DSP28335+FPGA+single chip microcomputer isdeveloped. The different operating states of the circuit breaker are tested
including opening/closing operation
autoreclosing operation
stage speed control and speed tracking etc. The test results show:when the control systemparameters are 10 kHz in PWM
the duty cycle is 80%
the mechanical parameters of the 126 kV vacuum circuitbreaker contents:the closing time is 38 ms
the opening time is 21 ms
the average closing speed is 2.24 m/s
theaverage speed is 3.63 m/s. The requirements of the opening and closing time and speed can be satisfied. The controltechnology of the motor operating mechanism can effectively control the operation state of the high voltage vacuum circuit breaker.
