A polar chart of the power converter supply current, comprising phase currents and rotor mechanical position information, is presented, in order to characterize the dynamic operation of a SRM drive. Power converter supply current can be used as additional information of extreme importance when a sensor error or failure occurs. Its analysis is then important and permits to develop appropriate fault...
This paper presents a general modeling and an experimental validation of a doubly fed induction generator (DFIG) based wind conversion system (WCS). The wind conversion system has been briefly presented. Then, the d q control of the grid side converter (GSC) has been detailed theoretically. Moreover, the decoupled active and reactive powers control of the DFIG has been presented. The last is carried...
This paper describes the models of a wind power system, such as the turbine, generator, power electronics converters and controllers, with the aim to control the generation of wind power in order to maximize the generated power with the lowest possible impact in the grid voltage and frequency during normal operation and under the occurrence of faults. The presented work considers a wind power system...
