摘　　要：最小断点集(MBPS)是复杂环网整定配合的起始点,它的求取往往会出现多组同基解。考虑线路对断点脆弱性的影响,并以带权重的线路介数作为衡量线路重要程度的指标,给出了一种多组同基MBPS的选取方法。最后通过算例验证了算法的有效性和可行性。The minimum break point set（MBPS） is the starting point for the relay setting coordination of complex ring network.During its solution,it always has multi-MBPS with the same cardinal number.Putting breakpoints of MBPS into the exit of the less vulnerable lines can greatly reduce the impact of breakpoint vulnerability on the grid.The weighted line betweenness of complex network theory is taken as an indicator to measure the importance of the line.Based on the indicator,a method for selecting the MBPS from multi-MBPS with the same cardinal number is proposed.The method estimates the betweenness of lines which the breakpoints of the MBPS calculation result belong to,then takes the sum of line betweenness of each MBPS,and finally chooses the MBPS of the least betweenness as the optimum MBPS.The numerical example can prove that this method can obtain the optimum MBPS.
