Výzkum vlastností systému s asynchronním strojem v generátorickém režimu.

Abstract

This thesis deals with asynchronous machines systems which operate in generator mode. An induction machine with squirrel cage rotor is used. The short description and mathematical model is presented at first. This model is thed used for realization of magnetic flux oriented vector control. Important thesis part is design of control structure for a drive with regard to generator mode of the induction machine. The following transfer principles describe how to get generator power back into the network through a voltage pulse rectifier. DC link voltage regulation is dealt from a side of pulse rectifier and even from an asynchronous generator side. The island mode is resolved by cooperation of the generator and accumulation element which is connected to the DC link. Experimental model with generator, power converters and control system with digital signal processor TMS320F28335 has been created. Developed control algorithm proves functionality of whole system. In the end of this work there are added results of generator operation modes captured on real model.
