传统的高压配电网接线模式分析分别从经济性和可靠性2方面评估不同接线模式的特性，将2方面完全剥离使得评估不够科学全面。为此，文章利用供电能力的概念，从可靠性和经济性相关联的角度对高压配电网的典型接线模式进行分析比较，对传统接线模式分析方法进行补充。首先建立了计及高压配电线路 N-1校验的供电能力计算模型并提出相应解法，其次建立分析和计算的边界条件并将供电能力计算模型应用于高压配电网的4种典型接线模式，最后通过计算和分析证明π型接线不仅具有较高的可靠性，经济性上也占优，并给出 T 型接线单条线路的经济容量，以指导高压接线模式的选择和应用。

In traditional connection mode analysis of high-voltage (HV) distribution network the features of different connection modes are assessed in two aspects respectively, namely the economy and the reliability, however the isolating economy from reliability makes the assessment results not comprehensive and rational. To make supplement to traditional connection mode analysis, utilizing the concept of load supply capability and considering the correlation between the economy and the reliability, typical connection modes of HV distribution network are analyzed and compared. Firstly, a load supply capability model, in which the“N-1” contingency of HV distribution line is considered, is proposed and corresponding solution is given; secondly, the boundary conditions for the analysis and computation is established and applying the proposed load supply capability model to four typical connection modes of HV distribution network; finally, the results of both calculation and analysis show that theπ-shaped connection mode not only possesses higher reliability but also it possesses advantage in economy, then the economic capacity single line under T-shaped connection mode is given to guide the selection and application of connection modes for HV distribution network.
