摘要
采用SVC改善双馈感应型风电场并网时暂态电压稳定性。通过仿真软件DIg SILENT/Power Factory建立静止无功补偿器(SVC)的控制模型。以实现风电场的低电压穿越(low voltage ride through,LVRT)的前提下应用SVC改善风电场的电压稳定性。仿真结果表明,采用SVC的并网风电场具有良好的动态性能,并且提高了风电机组在系统出现故障时的LVRT能力,确保了风电机组的连续运行和电网的安全稳定。
The SVC (static var compensator) is used to enhance the transient voltage stability of the wind farm of doubly fed induction when it is integrated with the power grid. The SVC control model is established in the DIgSILENT/Power Factory. On the basis of realization of low voltage ride through (LVRT), application of the SVC can improve the transient voltage stability of the wind farm. The simulation results shove that the grid-connected wind farm equipped with SVC has good dynamic performance with improved LVRT ability under the system fault, therefore the continuous operation and safety and stability of the wind turbine are guaranteed.
