双馈变速恒频风力发电机稳态运行特性

Steady-state operating performance of doubly fed variable speed constant frequency wind generation set

旨在根据双馈式变速恒频风力发电机的结构特点,机组以最佳叶尖速比变速运行,根据叶轮原动机输入的机械能和机组的发电功率曲线,研究双馈发电机的稳态特性,功率关系和转矩关系.通过转子励磁调节,找出在任何转差下,满足功率、转矩输出的工作点,给机组的控制方案设计提供了参考.

According to this Doubly Fed Variable Speed Constant Frequency Wind Turbine design, the machine can operate in variable speed maintaining optimum tip-speed ratio. Under the research of doubly fed generator steady-state performance, tracing the Wind Turbine Set power-wind speed curve, we can fine the suitable operation point, meeting the power out and torque out demand.
