摘要
可变速抽水蓄能机组采用双馈电机,其主要优势在于电动工况能够自动调节水泵输入功率,使得抽水蓄能机组能够自动跟踪电网频率变化。本文介绍了双馈电机目前存在的四种起动方式,阐述了可变速抽水蓄能机组水泵工况起动方式研究概况与发展现状,在此基础上重点分析了异步起动与定子短接起动两种起动方式,建立了数学分析模型,提出了转矩与功率表达式,为后续可变速抽水蓄能发电电动机的进一步研究奠定理论基础。
Doubly fed induction machine(DFIM) is preferred in variable speed pumped storage unit.The main advantage is the ability to control power in pumping mode and hence contributing to frequency regulation. This paper introduces four start-up strategies of DFIM, and reviews state-of-the-art in start-up of variable speed pump storage unit in pump mode. Further, both of the asynchronous method and short-circuit method in stator side are analyzed in detail, the analytical models are developed and the formulas of torque and output power are built, which lay the theoretical foundation of variable speed pumped storage generator-motor for future research.
