通过对风电场接入电网后电能质量影响的分析，以及风电场内部电能质量水平的测试，分析了风电场投运前后、不同运行方式等各个阶段静态无功补偿装置的补偿效果，探讨了在电网背景电能质量水平较差情况下，接入双馈型风机风电场后的电能质量情况。% After wind farm is connected to power grid,power quality will be affected. According to the analysis on the effects and the tests on the power quality of the internal part of wind farm,the compensation effects of static reactive power compensator under different operation modes after wind farm is connected to power grid are analyzed. What is more,the power quality after DFIG wind farm is connected to power grid is explored.
