Zusammenfassung:For a variable-speed wind power generation system equipped with the fixed-pitch wind turbine and doubly salient electro-magnetic generator (DSEG), the rotational speed can't be changed by pitch control. In this paper, a novel speed control method based on excitation current control of DSEG wind power generator (DEWG) in full range of wind speed is studied, based on their characteristics. It is composed of three-stage methods, which are maximum power point track (MPPT), constant speed control and constant power limit. So the safety, efficiency and stability of the whole system can be ensured. Effectiveness of the proposed methods is verified by Hardware-in-the-Loop (HIL) simulations, which adopt the real controller and real time simulation platform.
