摘　　要：在对复杂环网方向保护进行整定计算时,确定其最优配合顺序的核心步骤就是求解最小断点集(MBPS)。根据保护主后备的依赖关系,建立了计算MBPS的数学模型,将整定过程用一系列矩阵运算表示,并加入到约束条件。将保护重要度引入到目标函数中,利用人工蜂群算法对模型进行求解,得到最优MBPS。通过算例验证算法及模型的有效性。Determination of minimum break point set （MBPS） is the first step during setting and calculation of direction pro- tection in a complex multi - loop network. A new model for directly obtaining MBPS is established through the coordination de- pendency relationship of primary and backup relay. The setting process is expressed through a series of matrix operation which becomes the constraint. The relay protection importance is introduced into the objective function, and artificial bee colony algo- rithm is used for solving the model and obtaining the optimal MBPS. At last, it verifies the validity of the proposed algorithm and model by an example.
