在评估配电系统供电能力时，基于主变互联关系的供电能力计算方法的结果在一些情况下会产生过量裕度，为此，针对裕度产生的原因，以联络单元负载率矩阵为突破口，在保留原计算方法优势的基础上形成新的配电系统供电能力修正算法。首先搜索联络单元负载率矩阵的全局最小项，并以此为基准来调整同列元素；然后在满足“Ⅳ-_1，，校验的前提下将调整过程产生的裕度差额分配到同行各元素，依次遍历矩阵各行之后即完成修正过程；最终，通过某地区实际电网的算例分析，验证了该文中方法能够得到更加准确的计算结果。

In the evaluation on power supply capability of distribution system, the results of power supply capability from the calculation method based on interconnection of main transformers might lead to excess margin under certain conditions, therefore, in allusion to the reason leading to excess margin, starting with load rate matrix of liaison units and on the basis of reserving the advantages of original calculation method a new correction algorithm for power supply capability of distribution system is formed. Firstly, the global minterm in load rate matrix of interconnected transformers is searched, and taking the global minterm as the base all elements in the same column are adjusted; then under the premise that the N-1 guideline is satisfied, the difference of margin produced in former step is allocated to all elements in the same row, and the correction process is completed when ergodic correction of all rows in the matrix is fulfilled successively; finally it is verified that using the proposed method a more accurate calculation result can be obtained by analysis on calculation example of actual distribution network in a certain region.
