| 摘 要： | 在研究双馈型风力发电系统中网侧变流器基本工作原理的基础上,建立DFIG并网系统网侧变流器的数学及控制系统模型。为了更好地提升并网风电系统的控制效果,采用一种基于前馈解耦控制的双闭环控制策略对网侧变流器实行控制,以提高逆变波形及直流母线电压的稳定性。通过在仿真软件Matlab/Simulink中搭建模型进行仿真研究,验证控制策略的可行性及有效性。

| Abstract: | The mathematical and control system models of the DFIG Grid-side converter are built on the basis of studying the basic working principle of its. In order to enhance the control effect of the grid wind power system, a double-closed loop control strategy which is based on feed forward decoupling is utilized, which can improve the stability of the inverter waveform and DC bus voltage. Then the simulation models are built in Matlab/imulink software, so as to verify the feasibility and effectiveness of the control strategy which is used in the paper. |
