| 摘 要： | 在同步旋转坐标系下采用STATCOM(static synchronous compensator)和异步发电机风力发电系统的暂态数学模型,采用基于非线性反馈线性化的逆系统方法,构造出STATCOM的伪线性系统,然后采用滑模变结构控制理论设计出STATCOM的滑模变结构控制器。然后,以随机风和电网大扰动为例,采用STATCOM对并网风电场的电能质量和稳定性问题进行仿真。结果表明:采用该控制策略的STATCOM可很好地改善风电场的电能质量和稳定性。

| Abstract: | The transient mathematical model for the STATCOM and asynchronous generator in d-q synchronous reference frame was developed.It applied the inverse system method based on nonlinear feedback linearization theory.An inverse system model of STATCOM was deduced and a pseudo linear system was constructed.Then,by synthesizing the pseudo linear system,a sliding mode variable structure controller was proposed.Taking the wind speed changed at random and serious disturbance in power grid for example,using the detailed wind turbine model and squirrel-cage asynchronous generators the simulation of improving power quality and stability of wind farm connected to power grid by STATCOM was performed.Simulation results show that the power quality and stability of wind farm connected to power grid can be well improved by STATCOM. |
