| 摘 要： | 含虚拟惯量控制的风电场给系统的小干扰稳定带来了新的影响,在此背景下,研究利用风电场配置的静止同步补偿器(STATCOM)附加阻尼控制对电力系统低频振荡的抑制。利用阻尼转矩法分析了虚拟惯量控制对风电并网系统阻尼特性的影响,提出利用风电场中配置的STATCOM增强系统动态稳定的控制策略。基于自抗扰理论设计了STATCOM附加阻尼控制器,以改善系统阻尼特性。基于DIg SILENT平台搭建典型的4机2区域系统进行仿真,仿真结果验证了具有附加自抗扰阻尼控制作用的STATCOM能有效地阻尼系统功率振荡。

| Abstract: | Wind farms with virtual inertia control brings some new influences to the small disturbance stability. Under this background, the suppression of the low-frequency oscillation in power system by the additional damping control of STATCOM(STATic synchronous COMpensator) in wind farms is proposed. The influences of the virtual inertia control on damping characteristics of the wind power grid-connected system are analyzed by the damping torque method. Then, the control strategy to enhance the dynamic stability of the system with STATCOM in wind farms is proposed. Based on the theory of auto disturbance rejection, an additional damping controller of STATCOM is designed to improve damping characteristics. A typical 4-machine 2-area system is built on the DIgSILENT platform, and simulative results show that the STATCOM with additional auto disturbance rejection damping control can effectively suppress the power oscillation. |
