摘要
对加了节能装置的控制与保护开关(CPS)电磁系统动态仿真方法进行了研究。针对电磁系统的耦合电压平衡和达朗贝尔机械运动特征微分方程,利用Ansys软件包,采用有限元模型,进行了动铁心动态吸力和磁链的仿真;利用Matlab软件构建CPS电磁系统的机械模型,通过二元二次插值算法和四阶Runge-Kutta法,模拟动铁心的动态运动过程,获得了吸合过程中的电流、吸力、磁链等一系列物理量。为CPS电磁系统性能改进及实际产品优化设计提供了仿真环境下的理论支持。
The electromagnetic system dynamic simulation methods on control and protective switching device( CPS) with energy-saving device were researched. According to couple of electrical and mechanical differential equations which describe the dynamic behavior of electromagnetic system,using Ansys software package and FEM model,the dynamic attraction force acted on the moving core and coil flux were obtained. By constructing the mechanical model of CPS electromagnetic system,utilizing the binary quadratic interpolation algorithm and fourth- order Runge-Kutta method,the dynamic movement of moving core was simulated based on Matlab software package. Meanwhile,the current,attraction force and flux were also got. It provides theoretical support for CPS electromagnetic system performance improvements and product optimization design in simulation environment.
