三明地区电网无功优化配置的研究

Study on Reactive Power Optimal Allocation of SanMing Local Power System

系统分析了福建省三明地区电网的发展现状。针对三明地区电网存在的电压水平、网损等具体问题 ,建立了基于灵敏度分析的无功优化配置算法的数学模型。在现有无功配置的情况下 ,考虑多种负荷和丰水、枯水季节及检修运行方式的情况 ,通过对电网进行分析计算 ,形成无功补偿优化配置的方案。从而降低无功补偿设备的投资费用 ,提高三明地区电网运行的安全性、可靠性和经济性 ,其计算结果令人满意。

According to the existing problems such as voltage profile and energy loss in the SanMing local power system, the mathematical model of the reactive power optimization algorithm based on the sensitivity analysis is presented. Considering the different loads, different operation modes and the existing reactive allocation, the grid is analysed and caculated by the model, and the scheme of reactive power compensation is obtained. The security and efficiency of the SanMing local power system are improved.
