摘要
针对目前传统高压断路器操动机构分合闸过程中存在的动作时间长、位置与速度控制稳定性差以及触头碰撞风险高等缺点,文中设计了一种高压断路器操动机构永磁同步电机融合控制系统,利用位移-转速融合控制策略,实现了对高压断路器分合闸动作的快速、精准控制。基于高压断路器及其融合控制系统,建立了电机直驱高压断路器机械结构及传动特性数学模型,在讨论分析永磁同步电机矢量控制原理的基础上,提出了一种位移-转速融合控制算法,在高压断路器操动机构平台上验证了所提电机控制系统及其位移-转速融合控制算法。实验结果表明,断路器融合控制系统能够有效减少触头碰撞,提高了分合闸速度、系统稳定性和操作安全性。
In response to the drawbacks of long action time,poor stability of position and speed control,and high risk of contact collision in the current traditional high-voltage circuit breaker operating mechanism opening and closing process,this paper designs a permanent magnet synchronous motor fusion control system for high-voltage circuit breaker operating mechanism,which uses displacement speed fusion control strategy to achieve fast and accurate control of high-voltage circuit breaker opening and closing actions.This article establishes a mathematical model of the mechanical structure and transmission characteristics of a motor driven high-voltage circuit breaker based on the high-voltage circuit breaker and its integrated control system.The vector control principle of permanent magnet synchronous motor is explained,and a displacement speed fusion control algorithm is proposed.Finally,the proposed motor control system and its displacement speed fusion control algorithm were validated on the high-voltage circuit breaker operating mechanism platform.The experimental results showed that the fusion control system of circuit breaker effectively reduced contact collisions,improved opening and closing speed,system stability,and operational safety.
