交流励磁双馈发电机模型的建立与控制

众所周知,采用交流励磁双馈发电机的变速恒频风力发电系统具有许多优点,例如最大限度的捕捉风能,允许原动机在一定范围内变速运行,可灵活调节系统的有功和无功功率,起到功率因数补偿的作用。为了能比较清楚地研究变速恒频双馈风电系统的工作特性,需要建立一套能合理反映交流励磁双馈发电机运行特性、且适合应用于变速恒频风电机组性能研究的数学模型。

Construstion and Control of AC Excitation Double-Feedback Generator Model

As everyone knows,the variable speed constant frequency wind power generation system,which uses AC excitation double-feedback generator,has many advantages,such as the maximum wind energy capture,allows the prime mover in a certain range of variable speed operation,the flexible adjustment of system of active and reactive power,the power factor compensation effect.In order to better research on the operating characteristics of the variable speed constant frequency doubly-fed wind power system,need to establish a set of mathematical model that can reasonable reflect AC excitation double-feedback generator operation characteristics,and is suitable for variable speed constant frequency wind turbine performance study.
