摘要: 针对现有煤矿电网评估方法存在计算效率低、通用性差等问题，提出了一种改进的BFS-最小路评估方法。该方法首先利用广度优先搜索方法对配电网孤岛划分优化模型进行快速求解，然后结合孤岛运行范围，采用最小路法对供电可靠性进行评估。实验结果表明，该方法提高了电网薄弱环节的评估速度，评估结果安全可靠、精准有效。

Abstract: In view of problem of low computation efficiency and poor generality of existing evaluation method of coal mine power grid, an improved BFS-the minimal path evaluation method was proposed. The method uses the breadth-first search method to quickly solve division optimization model of distribution network island, and then adopts the minimal path evaluation method to evaluate reliability of power supply according to the operation scope of island. The experimental results show that the method improves evaluation speed of weak links of power grid, and evaluation results are safe, reliable, accurate and effective.
