摘　　要：为了解决快速接地开关高速分合闸操作中触头震荡严重和电机转矩脉动大的问题,提出了一种适用于快速接地开关的新型电机操动机构及其控制策略.设计一种采用SVPWM矢量控制策略的电机操动机构控制系统,完成控制系统的设计,搭建仿真模型并分析.开展应用于快速接地开关的电机操动机构分合闸特性试验.结果证明,采用SVPWM矢量控制策略进行开关的分合闸操作可以有效改善开关停止过程的震荡问题和电机转矩脉动问题,验证了电机操动机构设计的合理性.In order to solve the problem of severe contact vibration and large motor torque ripple during the opening and closing operation of fast earthing switch(FES),a new motor operating mechanism and control strategy suitable for FES was proposed.A control system of motor operation mechanism using SVPWM vector control strategy was designed,the control system design was finished,and a simulation model was built and analyzed.The opening and closing characteristic tests of motor operating mechanism applied to the FES were performed.The results show that the opening and closing operation,employing the SVPWM vector control strategy for opening and closing switch,can effectively solve the oscillation and motor torque ripple problems during switch-stop process.The rationality of motor mechanism design is verified.
