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。
在對複雜環網方嚮保護進行整定計算時,確定其最優配閤順序的覈心步驟就是求解最小斷點集( MBPS)。根據保護主後備的依賴關繫,建立瞭計算MBPS的數學模型,將整定過程用一繫列矩陣運算錶示,併加入到約束條件。將保護重要度引入到目標函數中,利用人工蜂群算法對模型進行求解,得到最優MBPS。通過算例驗證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 .
