Abstract

In order to improve the performance of vacuum circuit breakers with permanent magnet actuator（PMA）

restrain the transient process of power system effectively. During the process of VCB operation

the control system detects output signals of the sensors

and uses double-loop PID control method to control PMA

ultimately

achieves the tracking for the target reference contact travel and the current curve in excitation coil. In this paper

12 kV VCB with PMA is regarded as the controlled object

a control system based on DSP is designed. The results show that the control system designed with the new control method could effectively control the contact travel and current in excitation coil

ensure the characteristics of the contact in a controlled state

and improve the robustness and accuracy of the control system

and the closing time error of VCB within ±0.3 ms

lay the foundation for application of synchronous switching.
