摘　　要：提出一种交流接触器闭环控制联合仿真分析方法.基于PSCAD,根据电压平衡方程和达朗贝尔机械运动方程构建了电压平衡、机械运动子模型,并结合有限元分析软件,构建交流接触器的动态仿真模型,将其与PSCAD搭建的闭环控制系统相结合,组成联合仿真系统.该系统突出优点是将控制方案与动态仿真计算相结合,灵活改变控制方案,为接触器的智能控制提供仿真分析平台,为确定最优的控制策略和硬件电路结构提供科学依据.搭建硬件电路,通过实验验证联合仿真系统的可行性和准确性.采用该系统可以明显缩短硬件电路的设计周期,大幅度节约开发成本.A co - simulation method is presented for closed - loop control of AC contactor. The co - simulation model is established based on PSCAD software. It made up of dynamic simulation model and closed - loop - control system. The model of dynamic simulation mainly includes two sub - models for voltage equivalence and mechanical motion, and combined with finite elements. Combine control strategy with dynamic simulation calculation and flexible control scheme are advantage of the system. Al- so, it can be used as a simulation platform for intelligent control of AC contactor in order to find optimal control strategy and hardware structure. Finally, the feasibility and veracity were proved by experience. It is obvious to reduce the design cycle of hardware and the development cost by using this system.
