| 摘 要： | 当双馈风力发电机组受到外界扰动时,网侧变换器控制器的电感和支撑电容直接关系到系统的稳定性和快速响应能力。以双馈异步发电机的网侧变换器为研究对象,对基于电网电压矢量定向的双闭环控制策略进行了研究。首先对网侧变换器进行了数学建模,在基于电网电压矢量控制策略前提下给出了电容、电感参数大致选取范围,并通过在Simulink环境下搭建仿真模型,研究了电容、电感参数对系统响应的快速性、准确性、稳定性的影响规律。

| Abstract: | The capacitance and inductance parameters of the grid side converter have a strong relationship with the stability and the fast response of the control system when there is external disturbance on DFIG. Taking the grid side converter of DFIG as the research object, the double loop control strategy based on the grid voltage-oriented vector is studied. The mathematical modeling of grid side converter is firstly inferred and the approximate ranges of capacitance and inductance are also put forward based on the grid voltage-oriented vector control. Then the simulation model is built in Matlab/Simulink and the influences of the capacitance and inductance on fast response, accuracy, stability of control system are investigated. |
