摘要
介绍了现阶段的三大主流风力机型的应用及其特点,分析了大规模风电场并网对电网安全稳定运行带来的问题:一是改变电网潮流分布,二是对电网调度的影响,三是对配电网电能质量影响。基于当前的风电产业现状给出了风电功率预测、风电场中的电力电子设备及控制技术、低电压穿越等几个研究热点,并展望了未来风电发展前景。
Introduction was made to the application and characteristics of the three mainstream wind models at the present stage. This paper analyzed the inlfuences of safe and stable operation caused by large-scale wind farms power grid, including changing the power grid tidal current distribution, having impacts on the power grid dispatching and the quality of distribution network. In view of the pres-ent status of wind power industry, this paper proposed wind power prediction, power electronics device and control technology in wind farm, low voltage ride through etc research hotspot issues and prospected the trend of wind power development.
