摘要
从110 kV架空输电线路总损耗的基础上,用数学极值方法推导出了110 kV架空线路上负荷潮流变化时架空输电线路经济运行功率的计算公式,并得出当架空输电线路末端负荷按经济功率运行时,其线损率最低,线路的运行效率最高的结论,并进一步根据线路负荷潮流中无功含量的变化对线路线损率的影响分析了变电站无功补偿策略。
On the basis of the total loss on 110 kV overhead transmission lines the formula of economic load power on overhead transmission lines is deduced under the influence of the load flow changes, using mathematical extremum method.And when termi-nal load on overhead transmission lines operates according to economic power, the line loss is the lowest, and the line operation effi-ciency is the highest.Then the substation reactive power compensation strategy is analyzed according to the impact of reactive power content in load flow on line loss.
