A brand-new simulation method for the intelligent contactor was
proposed in this paper. The simulation method integrates spice
simulation of the circuit with dynamic simulation of the contactor.
Also the intelligent control strategy has been incorporated into the dynamic simulation. It realized the closed-loop point-by-point
co-simulation between the intelligent control module and the contactor. Multisim has a large number of spice models and can create power electronic circuit quickly and intuitively so as to design the hardware
of the intelligent control module. In addition, the voltage balance model and mechanical movement model of the contactor based on the dynamic differential equations of electromagnetic appliances were established in Labview. The nonlinear relationship between displacement, flux linkage
and excitation current of electromagnet mechanism were acquired by the finite element method, it was used in interpolation to calculate current of the coil while displacement and flux linkage have known in advance in the process of dynamic calculation. A two-way data channel has been built between Multisim and Labview. Both of the software perform nonlinear
time-domain simulation simultaneously and independently, and exchange
data at the end of each simulation time step. Taking intelligent AC contactor as simulation object, this paper analyzed the dynamic inductance, PWM control mode as well as closed-loop control strategy
for the velocity of the moving core. The co-simulation has been
verified to be an effective simulation method. |
