摘要 该文建立了无刷双馈发电机(BDFIG)考虑饱和效应的动态模型,详细分析了有功功率与无功功率分配,提出考虑饱和效应的功率模型预测控制策略。基于无刷双馈发电机的饱和特性进行励磁电感估算,实时修正每周期输入至控制器的电感参数,实现了功率的精确控制,保证控制侧电流的正弦度和较低的开关频率。通过对功率模型预测控制系统的仿真及实验研究,明确了影响饱和效应的运行因素,最后通过实验验证了所提控制策略的有效性。

Abstract:This paper proposes a model predictive power control strategy based on a dynamic model and analysis of the power distribution, considering the effects of magnetic saturation of the brushless doubly-fed induction generator (BDFIG). This strategy can realize accurate power control, so as to assure the quality of control winding current and reduce the switching frequency by estimating the magnetic inductance based on the saturation effect and correcting the inductance parameters input to the controller each period. Simulation and experiments were conducted on the BDFIG control system to identify the factors influencing the saturation effect, and validate the effectiveness of the proposed control strategy.
Key wordsBrushless doubly-fed induction generator    power model    model predictive control    saturation effect
