Confirming Capacitor and Resistor for Resistance-capacitance Braking of Three-phase Asynchronous Motors by Computer Simulation

By means of the steady-state equivalent circuit of three-phase induction generator, the optimization method was applied to calculate boundary values of the excitation capacitor. According to the dynamic mathematical model of three-phase induction machine in d-q axes stationary coordinates system, the magnetizing inductance variation with the transient saturation of main flux path was taken into account and SIMULINK simulation model was worked out whichapplied to resistance-capacitance braking operation process of three-phase asynchronous motors. The simulation model was applied to calculate braking resistance through emulating resistance-capacitance braking operation process of three-phase induction motor. An effective mean of selection of the exciting capacitance and braking resistance was offered for the designer of the brake apparatus.
