中文摘要: 配电网规划设计导则对中低压配电线路的供电距离提出了原则性要求,但考虑到实际情况和技术经济合理性,电网建设实施过程中往往有所突破。以允许电压降落作为约束条件,以典型配电线路为研究对象,采用改进损失系数法,推导配电线路最大供电距离的计算公式,计算得到中低压配电线路在不同负荷水平下的最大供电距离。讨论了经济电流负荷水平下的最大供电距离,以及功率因数和首端运行电压对最大供电距离的影响,为配电网规划建设提供决策参考。
Abstract:Although the distribution network planning and design guidelines put forward the principle requirements for the power supply distance of the medium and low voltage distribution lines, there are often breakthroughs in practice whentaking into account the actual situation and technical and economic rationality. With the constraint condition of allowing voltage drop,this article calculates the maximum power supply distance of the typical wire type medium and low voltage distribution lines at different load levels, using improved loss coefficient method. Furthermore, the paper also discusses the maximum power supply distance under the economic current load level, as well as the influence of the power factor and the head-end operating voltage on the maximum power supply distance. It provides a decision-making reference for distribution network planning and construction.
