摘要
双馈发电机的有功(P)、无功功率(Q)的解耦控制是变速恒频(VSCF)风力发电系统的关键技术。本文阐述了变速恒频风力发电系统的工作原理,在分析双馈感应电机的动态数学模型以及定子磁链定向矢量控制的基础上,介绍了一种有效的有功、无功功率解耦控制方法。Matlab仿真结果表明该控制方案能够很好地实现双馈电机的有功、无功功率的解耦控制,验证了该控制策略的正确性。
The decoupled control of active and reactive power is a key technology of variable speed constant frequency （VSCF） wind energy generation system. This paper presents the principle of variable-speed constant-frequency wind energy generation. By analyzing the mathematical model of a doubly-fed induction generator（DFIG） and the field-oriented vector transformation control scheme, useful method of independent active and reactive power control is proposed. Simulation of this control system by using Matlab software indicated that the control strategy could decouple the stator power control of the DFIG efficiently, and validated the correctness of the proposed strategy.
