摘要
双馈异步风力发电机组因其技术成熟、性价比高等优点,已成为当前兆瓦级风力发电的主流机型。将动态相量法引入双馈异步发电机的建模,并在平衡和不平衡条件下进行仿真研究,通过与时域模型的比较,验证了所提出模型的准确性、快速性。为双馈异步发电机进行仿真分析提供了新的选择。
Doubly-fed induction wind turbines have become the mainstream of MW-class wind power generation mode,because of its mature technologyand low costs.The dynamic phasor method is nonlinear,and haslarge signal,time-invariant advantages.This paper introduces dynamic phasor to modeling of doubly fed induction generator,and simulates conditions of balanced and unbalanced voltage.This model has excellent tracking behavior,fast simulation speed and is more valuable for transient simulation and control design.It provides a new choice for accurate and rapid study of doubly-fed induction generator running simulation.
