RISControl of DFIG Wind Turbines Based on Indirect Matrix Converters in Short Circuit Mode to Improve the LVRT Capability
Year: 2013
Abstract:
Nowadays, the doubly-fed induction generators (DFIGs) based wind turbines (WTs) are the dominant type ofWTs. Traditionally, the back-to-back converters are used to excite the rotor circuit of DFIG. In this paper, an indirect matrix converter (IMC...
Direct decoupled active and reactive power control of Doubly Fed Induction Machine without rotor position sensors and with robustness to saturation and parameter variation
Year: 2011
Abstract:
in this paper a new Direct Power Control method of the Doubly Fed Induction Machine without the use of rotor position sensors is presented. The method is based on estimating the stator flux in the rotor reference frame, ...
