抽水蓄能电站可变速机组启动技术研究

摘要

The mathematic model of AC-excitation variable speed pumped storage unit (ACE-VSPSU) with short-circuited stator is established.Based on the model,the stator flux-oriented self-starting vector control philosophy is given and the selfadaptive method for offset rectification of rotor position sensor is also studied.The self-starting vector control philosophy and the self-adaptive offset rectification method are tested in the dynamic simulating system of ACE-VSPSU.The results show that the proposed vector control philosophy and offset rectification method can achieve perfect self-starting performance.%建立定子绕组短接时ACE-VSPSU的数学模型,提出了便于实现的定子磁链定向ACE-VSPSU自启动矢量控制策略以及自适应的偏移量检测方法,对转子位置传感器偏差进行校正.通过ACE-VSPSU动模仿真系统,对提出的策略及方法进行的仿真验证结果表明,该方案可获得良好的启动性能.
