Abstract

The article is devoted to creation of induction motor drive (IMD) mathematical model in the Matlab/Simulink simulation environment, which serves as a prototype of the electric drive for a special high-power pumping unit. The model makes it possible to calculate static and dynamic characteristics at different control laws of voltage source inverter (VSI). To verify the model, the experimental setup was created, which includes a power source (PS), a servocontroller (SC) designed to control a frequency-controlled electric drive with support of information feedback sensors, which includes a frequency converter (FC) with the method of pulse-width modulation (PWM), cable line (CL), a low power squirrel cage induction motor (IM), rotary incremental encoder (EN) to measure the speed of IM, whose shaft is connected to the shaft of DC generator with permanent magnetic excitation (DCG) through a rigid coupling, resistive load. Simulation results were obtained for the scalar method of frequency control. In the process of adequate simulation model validation with experimental data, the nonlinearity of the motor magnetic circuit is taken into account. It was found that the proposed correction of the motor equivalent circuit inductances allows us to significantly reduce the value of difference between the model and the experimental data in different modes of motor operation. Thus, for example, for a half value of the supply voltage frequency, the mean square error between the calculated and experimental data for stator current and motor speed decreased by 3.5 and 1.5 times, respectively, at starting and 4.5 and 1.4 times in steady-state mode.
