最小断点集的简化计算与组数扩充

Simplified Calculation of Minimum Break Point Set and Its Sets Increasing

摘要:

为简化最小断点集的计算，通过割节点对电网进行分割。在每个子网中，根据主后备保护配合关系，形成了保 护配合矩阵，并对矩阵进行化简以降低保护配合矩阵的维数，通过动态调整保护配合矩阵得到子网的最小断点集。 将最小断点集的分布规律引入到计算过程中，扩充最小断点集的组数。算法在降低计算量的同时可得到多组最小断 点集。通过算例验证了所提出方法的简易性和实用性。

Abstract:

In order to simplify the calculation of minimum break point set ( MBPS) ，firstly the power grid is divided． The protective coordination matrix is generated by the relationship of main and backup protection in every sub － network． The matrix is simplified to decrease the dimension． The MBPS of sub － network is obtained by adjusting the protective coordination matrix dynamically． For increasing the sets of MBPS，the MBPS distribution law is introduced． The proposed method can reduce the calculation capacity and get much more sets of MBPS． The simplification and practicality of the proposed method is verified by an example．
