摘　　要：电网末端并网风电的容量与日俱增,大型风电场对电网的无功支持与安全响应能力至关重要,提升风电场的电压穿越能力迫在眉睫。文章以云南某风电场SVG设备电压穿越功能改造为例,对改造前、后的电压穿越性能进行测试分析,验证了SVG电压穿越改造的成效。The capacity of grid connected wind power at the end of the grid is increasing day by day.Large-scale wind farms are very important to the reactive power support and safety response ability of the grid,so it is urgent to improve the voltage ride through ability of the wind farms.In this paper,taking the voltage ride-through function transformation of SVG equipment in a wind farm in Yunnan as an example,the voltage ride-through performance before and after the transformation was tested and analyzed,and the effectiveness of the SVG voltage ride-through transformation was verified.
