中文摘要 |
针对电网故障下对双馈风力发电机网侧变换器的影响, 本文采用滑模变结构控制方法, 提出了采用增加瞬时功率前馈补偿的高阶滑模变结构控制策略, 为此首先简要的分析了双馈风力发电机中双脉宽调制(PWM)型变换器的结构和控制原理, 然后根据网侧变换器的数学模型, 提出对网侧变换器采用电网电压定向矢量控制, 以实现交流侧单位功率因数和直流环节电压控制. 提出的方法提高了系统响应速度, 克服参数变化和外电压波动的影响. 仿真结果表明了该策略的有效性. |
英文摘要 |
For the grid side converter, this paper proposes a higher-order sliding mode control(SMC) plus a transient power feedforward PI control to deal with the grid failure and to keep the direct current(DC) voltage stable. Firstly, we
analyze the structure and control principle of the double pulse width module(PWM) converter in double-fed induction generator(DFIG). According to the mathematical model of the grid side converter, the paper adopts the voltage orientation vector control principle to realize the unity-power-factor for the alternating current(AC) side and the voltage control in the DC loop. The proposed method speeds up the system tracking, and stabilizes the system under the influence of the external disturbances. Simulation results validate the accuracy and effectiveness of the control strategy proposed in this paper. |
