基于配电网低载线路合并运行的降损分析研究

线损率是配电网经济运行的重要考核指标之一,降低线路损耗对配电网经济运行具有重要意义。本文提出了将供电范围邻近的低载线路合并运行、减少台区运行数量的供电模式,分析了该运行模式在满足配电网运行可靠性的前提下降低线路损耗的可行性以及线路合并运行供电模式的应用前景。研究结果表明,在不影响供电可靠性的前提下,该模式对于降低线路损耗具有较为明显的效果。

Research on Reducing Line Loss Based on Combined Operation of Low-load Lines in Distribution Network

As the line loss rate is one of the important evaluation indicators of the distribution network,it is of great significance to reduce the line loss.This paper proposes a line operation mode that combines lowload lines adjacent to the power supply range to reduce the number of distribution transformers in operation,and analyzes the feasibility of reducing line loss and application prospects under the premise of meeting the reliability of the distribution network.The research results show that it has a significant effect on reducing line losses without affecting the reliability of power supply.
