摘　　要：针对宁夏地区某风电场功率因数偏低,无法并网的情况,从性能与经济性两方面考虑,提出了基于SVG+FC方法的风力发电系统无功补偿方案,并详细分析了二者之间的优化配比问题,以提高输电功率因数。仿真结果表明:补偿方案在投资、性能和补偿效果方面均优于其他各种控制方式,具有可行性和经济性。Aiming at the problem of low power factor not to interconnect with the power grid for a windfarm in Ningxia, considering the performance and economy, puts forward the reactive powercompensation scheme based on SVG＋FC method of wind power generation system, analyzes in detailthe optimization blending ratio of the two method so as to increase the power factor of powertransmission. The simulation result shows that the compensation scheme excels other various controlmodes in investment, performance and compensation effect, has the feasibility and economy.
