Perederiy O. Сontrol system of inverter-simulator AC electric motors for testing power converters

Object of research - the energy processes in the separate power-supply system with a hydrogen- oxygen fuel Object - electromagnetic processes in frequency converters and AC motors. Goal - development management system static inverter-simulator that implements load test frequency converter according to the parameters given engine load determined according to the nature of the working machine. Research methods - automatic control theory, Z- transform method, mathematical modeling, the electric theory, the method of physical modeling, method for the experimental study. Bottom line - the method of calculation of the phase currents of the digital controller inverter-simulator in accordance with the assignment of discrete mathematical model of the motor, the method of the structure of the inverter-simulator to simulate the AC motors in the start mode, increased torque load, voltage and frequency variation of cyclic loading. Novelty - received a further control method of semiconductor inverter-simulator - load simulator dynamoelectric machine, wherein the use of discrete models of AC motors and discrete regulators of inverter, which agreed to the sampling period, which allows to take into account the output voltage of the converter and the test conditions of the engine, first developed a mathematical load device model system for the study load, which takes into account the peculiarities of the voltage inverter with pulse-width modulation, which allows for quality control phase currents regardless of frequency modulation and load test drive, the first time established the influence of timing and parameters of the power circuit of inverter-simulator on the performance of the phase currents regulation that allows you to set the requirements for the implementation of the load device. Degree of integration - the results obtained in this thesis, are introduced into the production process, as evidenced by the relevant regulations. Scope of use - results of the thesis can be used in the electric power industry for the improvement of tests of frequency converters, as well as in the educational process.
