Abstract

Stable timing is essential when synchronous closing and opening operations are required.The drifts of a synchronous vacuum circuit breaker’s operating times can be caused by the operating conditions such as the variations of the ambient temperature

the control voltage

the contact wear and the idle time.In order to compensate the influence of temperature

control voltage

ageing and other disturbance and guarantee that the operating times will remain stable in long term

a high accurate position control method is adapted to control the movement of the synchronous vacuum circuit breaker based on a comparison of the movement of the switching with the optimal reference trajectory.First

the dynamistic model of a permanent magnetic actuator vacuum circuit is simulated by using MATLAB package and a fuzzy controller is designed to realize the high accuracy position control.Second

the performances of the fuzzy control algorithm based on position control are simulated and optimized.Finally

a vacuum circuit breaker with position control has been tested.The testing results show that the position closed-loop control meet with IEC 62271-302 requirements to consistency operating times in synchronous switch

and the drifts of operating times are less than±0.5 ms.
