无传感器双馈异步风力发电机直接转矩控制

针对有传感器控制的若干缺点,提出一种新塑无传感器控制方法,其采用基于模型参考自适应模块的闭环算法辨识双馈异步风力发电机的转速和转子位置;利用仿真工具Matlab7.1/simulink和S-Function构造仿真模型,仿真结果表明,其具有很好的动态和稳态性能,转速和转子位置观测精度较高,通过控制发电机的转矩、调节发电机转子转速,稳定了发电机输出电能的频率,达到了双馈异步风力发电机平滑稳定的调速目的,适合于双馈异步风力发电系统的变速恒频运行.

Sensor-less Direct Torque Control of Doubly Fed Induction Wind Generator

For a number of shortcomings for controlling of sensor,a new sensor-less control method was proposed for doubly fed induction wind power generator to detect rotor speed,rotor position,which based on model reference adaptive closed-loop algorithm.Use simulation tools Matlab7.1/simulink and S-Function constructed simulation model,the simulation results showed that it had a good dynamic and static performance,achieved high accuracy of speed and rotor position's observation,stabilized the frequency of generator...
