摘要
该文提出了一种新的智能交流接触器仿真方法,将SPICE电路仿真与接触器动态仿真完全集成,实现了智能控制模块与接触器本体一体化的逐点闭环仿真系统。在Multisim电路仿真软件中进行智能控制模块的底层硬件电路设计,在Lab VIEW中构建接触器的动态仿真程序,同时构建Multisim和Lab VIEW之间的双向数据通道,两个独立的仿真程序同时进行非线性时域仿真,然后在每一个仿真步长结束时交换数据,进行一体化仿真。通过一体化仿真确定合理的接触器运动过程控制方案,同时引入数字变流技术,开发了智能交流接触器电流闭环数字控制模块,并进行相关实验,验证了一体化仿真及数字控制的有效性。
A brand-new simulation method for the intelligent AC contactor was proposed. The simulation method integrated the SPICE simulation of the control module with the dynamic simulation of the contactor and realized the closed-loop point-by-point co-simulation between the intelligent control module and the AC contactor. The underlying hardware circuit of the intelligent AC contactor can be designed in Multisim. And the dynamic model of AC contactor can be designed in LabVIEW. In addition, a two-way data channel has been built between Multisim and LabVIEW. Both of the softwares perform the nonlinear time-domain simulation simultaneously and independently, and exchange data at the end of each simulation time step so as to realize the co-simulation. The co-simulation system can find a reasonable control scheme for the intelligent AC contaCtor. At the same time, the digital control technology has been introduced and a current closed-loop control module for AC contactor was designed. The co-simulation and the digital control have been verified effectively.
