摘要
提出一种风电场中用配电静止同步补偿器(distribution-static synchronous compensator,D-STATCOM)来减少风电并入配电网对电网影响,提高其动态性能。首先给出D-STATCOM的动态模型,然后比较加入D-STATCOM前后的电压变化情况。结果表明,将D-STATCOM应用到风电场中,在风速发生扰动时利用D-STATCOM的电压控制补偿作用和响应速度快的特点,以迅速改善电场电压的稳定性,从而提高配电网的电能质量。
In order to reducing the impact of wind power into the power distribution network, and improving their dynamic performance, D-STATCOM is used in wind farms. First, the dynamic model of D-STATCOM is offered. Then comparing the voltage changes before and after D-STATCOM is added. It is showed that using the characteristics of voltage control compensation role and fast response of D-STATCOM to quickly improve the voltage stability of the electric field by applying D-STATCOM to the wind farm, thereby enhancing the quality of electricity distribution network.
