摘要
提出了基于灰色GM(1,1)模型负荷预测的500 kV变电站经济运行规划方法。首先介绍了变电站常用的经济运行措施,针对500 kV变电站的特点,从理论角度分析了三绕组主变压器的运行损耗、经济运行区间,制定了基于临界负载功率的多主变经济运行方式;而后提出了基于GM(1,1)模型的变电站负载滚动预测方法;最后制定了基于负荷预测的500kV变电站经济运行规划方法。算例分析表明本经济运行规划方法具有有效性和实用性。
A method is proposed for 500 kV substation economic operation planning based on GM （ 1, 1 ） load forecasting. First sev eral common measures for substation economic performance are introduced. Considering 500 kV substation characteristics, the opera tion loss and economic operation range of threewinding transformer is analyzed from a theoretical perspective, and the multitransform er economic operation mode is developed based on critical load power. Then the substation load rolling prediction method based on GM （ 1, 1 ） model is proposed. Finally, the 500 kV substation economic operation planning system based on load prediction is tbrmula ted. Efficiency and practicability of the system is showed through an example.
