在复杂环网的继电保护整定计算中，最小断点集（MBPS）的求取往往会出现多组同基解。综合考虑节点和线路对断点脆弱性的影响，并基于节点和线路电气介数，提出了保护重要度概念，以此作为衡量保护脆弱性的指标，给出了一种多组同基最小断点集选取方法。最后通过算例验证了算法的可行性和有效性。

In the coordination and setting of relay protection for the complex ring-network, selecting the minimum break point set （MBPS） is almost sure to have several identical cardinal MBPSs. This paper presents a method for selecting optimum MBPS from Muiti-MBPSs with the same cardinal number, which takes into account the nodes and lines＇impact on the vulnerability of breakpoints comprehensively, then proposes conception of indicator of relay＇s vulnerability. Finally, the feasibility and effectiveness of the method proposed is proven with the example of simulation.
