Frequency Method of Regulating the Speed of an Asynchronous Motor as a Simulator of a Wind Wheel of a Wind Power Generator

The article conducts a study of the developed prototype of a permanent magnet synchronous generator (PMSG) based on simulation modeling and experimental tests. To conduct experimental studies, a test stand has been developed with the ability to regulate the rotation speed of the PMSG rotor up to 500 rpm. The prototype is a three-phase synchronous machine; the stator magnetic system is based on the stator magnetic system of an asynchronous electric machine. As part of a modular-type wind turbine, the PMSG can operate at different combinations of enabled/disabled independent modules – electromagnets (EM). The output voltage is close to a sinusoidal shape (coefficient non-sinusoidality less than 1%), practical application of modular type PMSG preferably when the wind load changes, which reduces the negative influence of external factors.
