双馈风力发电机滞环矢量控制策略的研究

双馈风力发电机控制是整个风力发电系统的核心部分,常规的控制方法十分复杂,且动态响应性能一般。本文采用定子磁链定向矢量技术,引入滞环电流控制,建立了新的转子励磁控制策略,简化了控制过程,提高了动态响应性能。利用PSCAD/EMTDC平台,仿真研究并验证了该控制方案的正确性和有效性。

Study on the Hysteretic Vector Control Strategy for Doubly Fed Wind Generator

The control of doubly fed induction generator system is the hard core of the wind power. The routine control strategies are very complex and performance is commonly. In this paper, a new control method for rotor excitation is established at the stator flux linkage orientation. Meanwhile, hysteretic current control technology is introduced into modulate of rotor side converter to predigest control system. Simulation study is carried out on the platform of PSCAD/EMTDC and validates the proposed strategy.
