为研究含多风电场地区电网的无功优化方法，根据地区电网和风电场的运行特点，以最小网损为目标，利用电力系统分析软件 PSD-BPA和 PSD-OPF无功优化程序建立了含多风电场地区电网的无功优化模型。以广东省某地区电网为例，分别计算风电场作为负荷节点和电压控制节点时的无功优化结果。计算结果表明：无功优化后节点电压分布更加合理，网损显著降低；风力发电机作为负荷节点和电压控制节点对系统的影响不大。

For studying reactive power optimization method for regional grids with multiple wind farms,this paper introduces establishment of reactive power optimization model for regional grids with multiple wind farms by using electric power sys-tem analysis software PSD-BPA and PSD-OPF according to running characteristics of regional grids and wind farms which takes minimum grid loss as target. Taking some regional grid in Guangdong province as an example,reactive power optimi-zation results of wind farms respectively as load node and voltage control node were calculated. Calculation results indicated that voltage distribution after reactive power optimization was more reasonable and the grid loss was obviously decreased. In addition,as load node and voltage control node,the wind power generator had small impact on the system.
