绕线式异步风力发电机的最大风能追踪控制

摘要

以双 PWM 交流励磁电源控制的绕线式异步风力发电机系统为对象，研究了有功功率和无功功率的确定原则和计算方法，进而研究了双馈异步电机的功率解耦控制。给出变速恒频风力发电机最大风能追踪的控制策略，仿真研究表明基于电网电压定向的矢量控制策略，通过转子侧变换器和双馈电机之间的数学模型，能够有效地实现最大风能追踪。提高风电机组的运行和运行效率。%This paper base on wound rotor asynchronous wind power generator system controI ed by doubIe PWM ac excitation power suppIy as the object of study,Study of the active power and reactive power determination principIe and it's caIcuIat-ing method,then studied the power decoupIing controI of doubIy-fed induction motor.Given variabIe speed constant fre-quency wind turbine maximum wind power tracking controI strategy,simuIation resuIts show that based on grid voItage ori-ented vector controI strategy,the mathematicaI modeI of the rotor side converter and doubIy-fed motor.
