A novel voltage-modulated direct power control (VM-DPC) is first designed for a back-to-back (BTB) converter in the doubly fed induction generator (DFIG) system. The proposed VM-DPC built stator stationary reference frame (??). method uses simple feed-forward and feedback structure without phase-locked loop Park transformation. Therefore, it can be easily implemented BTB converter. Another esse...

The Brushless Doubly Fed Reluctance Machine (BDFRM) is an emerging alternative for variable speed drive systems, providing a significant downsizing of the power electronics converter. This paper proposes new view on machine equations, allowing reuse standard control system design conventional synchronous and asynchronous machines: cascade with inner current control- outer loop. assumptions simp...

In this paper, a novel voltage control strategy of stand-alone operation brushless doubly 9 fed induction generator for variable speed constant frequency wind energy conversion systems 10 was presented and discussed particularly. Based on the model of the generator power system, the 11 proposed direct flux control strategy employs a nonlinear reduced-order generalized integrator 12 based resona...

In this work, a robust nonlinear control technique of a doubly fed induction generator (DFIG) intended for wind energy systems has been proposed. The principal idea in this article is to decouple the active and reactive power of the DFIG with high robustness using the backstepping strategy. The principle of this control method is based on the Lyapunov function, in order to guarantee the global ...

This paper describes optimal reactive power control of a doubly fed induction generator (DFIG), which is widely used in a distributed generating plant. Although its structure is similar to that of an induction motor, its reactive power control is more complicated. In this paper, steady-state power transfer equations are derived and developed for a doubly fed structure of the induction generator...

Recently, an increasing number of multi-MW (1MW and up) wind generating set are being developed with a variable speed-variable pitch (VS-VP) control strategy to improve the fast response speed and get optimal energy. But the power generated by wind turbine changes rapidly because of the continuous fluctuation of wind speed and direction, and wind energy conversion systems are of strong nonlinea...

Wind is one of the most widely used nonconventional sources of energy. A back-to-back PWM converter is used as the excitation power supply for the doubly fed induction generator (DFIG) wind power generation of variable speed constant frequency (VSCF).The Simulink model and control strategy of converter which is connected between rotor and grid is analyzed. Stator-flux oriented vector control ap...

In this paper performance analysis of Doubly Fed Induction Generator under abnormal condition is analysed. In recent years, this series compensated transmission system will produce unwanted effect of sub synchronous resonance. Super Conducting Magnetic Energy Storage (SMES) provides an efficient damping for sub synchronous resonance that will enhance power system stability in addition to real a...
