Paper Title:
Study on the Power Control Method of a Stand-Alone Wind Energy System Based on DSEG
  Abstract

The Stand-Alone wind energy supply system equipped with a doubly Salient Electro-Magnetic Generator (DSEG) is presented in this paper. First, the analysis of the operating characteristics of wind turbine and DSEG is introduced. Based on the strategy of power signal feedback (PSF), the excitation current of DSEG is regulated, as a result, Electro-Magnetic torque of the DSEG is controlled and the maximum wind energy tracking is achieved. Battery is employed as an energy storage device and interfaced to the wind energy system through bidirectional DC/DC converter. The control strategies of the bidirectional DC/DC are proposed to balance the power differences between the generator and the power the load, so that voltage of the DC bus could be constant under varying wind speed and load. The simulation results show the effectiveness of the control methods.
