Research on Direct Power Control Strategy for Brushless Doubly-Fed Machine

文章针对无刷双馈感应发电机统一矢量模型进行理论分析,提出了一种直接功率控制策略,该策略对于无刷双馈感应发电机的有功功率和无功功率的控制效果较好,具有较强鲁棒性。随后在Matlab/Simulink中建立了无刷双馈发电机风力发电控制系统的仿真模型进行仿真试验研究,验证了控制系统有良好的性能。

In this paper,a Direct Power Control System is proposed for the Brushless Doubly-Fed Induction Generator(BDFIG)based on the theoretical analysis of generalized vector model.The control system can effectively control the performance of the active power and reactive power.Then,an extensive simulation verification,using MATLAB/Simulink,is conducted on a 15 kW BDFIG.Simulink results show that the system has good control performance.
