Abstract:
The three-phase models are realized with momentary values of the electric quantities. This enables study of all types of slow and fast transients – starting of aggregates, operation at change of the load, supply voltage or its frequency, incomplete phase regimes, short circuits, etc. In the electric power stations, the driving of mechanisms of the auxiliaries is usually performed by induction motors. There is a three-phase model of classical induction motor in Matlab/Simulink. In the present paper, development of models of 6kV electrical machines aggregates (EMA) with twospeed induction motors and EMA with mechanical regulation of the frequency of start-up revolving is presented on the basis of the three-phase model in Matlab.
