| 摘 要： | 在无刷双馈电机(BDFM)的国内外研究及应用现状基础上,分析其工作原理和变速恒频风力发电系统的实现。根据BDFM在d-q坐标系的动态数学模型,提出变速恒频运行条件下的功率控制策略,设计出基于d-q坐标系的功率控制系统。应用此控制策略和控制系统,对一个典型BDFM运行在空载条件下的动态特性进行仿真验证和分析。理论研究与仿真结果证明了本功率控制策略和控制系统用于BDFM风力发电的可行性及有效性。

| Abstract: | The domestic and international development and application of brushless doubly-fed machine(BDFM) used in wind turbines are introduced. Its operating principle and the realization of constant frequency controlled with variable speed in wind power generation are analyzed.Based on its dynamic mathematic model under d-q reference frame,a novel power control strategy is brought forward and a power control system is designed.Using the proposed control system and strategy,the control effects are simulated with typical parameters of an experimental BDFM.Theoretical study and validated simulation results have shown that the proposed power control method based on BDFM in wind power generation is feasible and effectual. |
