| 摘 要： | 最大供电能力(TSC)是衡量配电网建设水平的新指标,而馈线联络是影响TSC的关键因素,文中研究了馈线联络对TSC的影响。首先,定义了加权联络均衡度、联络效率等量化描述联络位置和联络效率的指标。其次,针对联络位置对TSC的影响,给出同等联络规模下TSC与加权联络均衡度的关系。再次,针对联络规模对TSC的影响,给出TSC、联络效率与联络规模的关系。最后,分析了不同联络建设次序下的TSC变化规律和特点。研究初步揭示了馈线联络对配电网TSC的作用机理,为优化配电网提供了新的依据。

| Abstract: | The total supply capability (TSC) is a new index of assessing the construction level of distribution networks while the feeder link is a key factor for improving the TSC. The influence of the feeder link on the TSC is investigated. First, the weighted balance degree of feeder links, feeder link efficiency and other relevant indices for quantitatively describing the link position and efficiency are defined. Secondly, in view of the influence of link position on TSC, the relationship between TSC and the balance degree in the same scale of feeder links is given. Thirdly, considering the influence of feeder link scale on TSC, the relationship between TSC, link efficiency and feeder link scale is presented. Finally, the laws of change and characteristics of TSC in different construction orders of feeder links are analyzed. The influence mechanism of feeder links on TSC for distribution networks is revealed, providing a new basis for optimization of distribution networks.
