摘　　要：本文从稳态经济运行的角度出发,提出一种基于经济压差理论的含风电场系统无功补偿容量配置计算方法,该方法主要考虑了风功率的出力变化情况。采用该方法对含风电的新英格兰10机39节点系统进行了无功配置分析,根据所得的无功容量配置分布情况,设计了一种易于实现的方案,并对该配置方案降低线损的有效性进行了比较分析。验证了以固定补偿为主的无功配置方案在含风电场系统中可以有效降低电网有功损耗,提高电网运行效率。To improve the economy of power system with wind power,a new method was proposed to calculate the configuration of reactive compensation capacity.In this method,the economic voltage difference theory and Monte Carlo simulation was applied,and the fluctuation of wind turbine output was considered.Some analyses were made by this method on the New England 10-machine 39-bus power system with a wind farm integrated.And based on the distribution of reactive compensation re-quirements,an easy-to-realize scheme was designed and its effectiveness to reduce line loss and to en-hance operation efficiency was proved.
