一种计算环网方向保护配合最小断点集的实用算法

提出了保护依赖度的新概念，将最小断点集的计算归结为环网中所有保护依赖度大小的比较，并根据比较结果确定断点，直到找出环网的最小断点集为止，同时通过判断某保护的后备保护集是否为空集的方法来求解相对顺序矩阵，结果表明该方法非常简单并且有效，大大降低了问题的计算复杂性。

A PRACTICAL ALGORITHM TO DETERMINATION MINIMUM BREAK POINT SET FOR OPTION COORDINATION OF DIRECTIONAL PROTECTIVE RELAYING IN MULTILOOP NETWORKS

A new concept named relay protection dependence-dimension is put forward. Comparing the dependence-dimension is used to compute the minimum break point set (MBPS), and the process is not stopped until all break points of the multiloop networks are discovered and the MBPS is found. By checking the number of a backup protection elements set is zero or not, this paper can calculate the relative sequence matrix (RSM). The result shows that the algorithm mentioned above is very simple and effective.
