摘　　要：本文提出了一种适用于故障应急处理的输电网络重构优化规划方法,建立混合整数二次约束规划的输电网应急重构优化数学模型,首先基于灵敏度分析选择候选重构支路集以减少计算规模,其次基于直角坐标系建立二次型交流潮流约束,最后建立短路电流约束的线性模型,并通过WARD等值降低短路电流约束规模。模型的求解采用原对偶内点法及分支定界法。通过C++编写了仿真程序,对某省级输电网模型进行了仿真分析,验证了所提模型的正确性和算法的有效性。A transmission network reconfiguration optimization planning method for fault emergency treatment is proposed in this paper.A mathematical model of mixed integer quadratic constrained programming optimization for transmission network emergency reconfiguration is established.Firstly,candidate reconstruction branch sets are selected based on sensitivity analysis to reduce the computational scale.Secondly,a quadratic AC power flow constraint is established based on a rectangular coordinate system.Finally,a linear model of short circuit current constraints is established and the scale of the constraints is reduced through the WARD equivalence.The model is solved by the primal dual interior point method and the branch and bound method.A simulation program was written in C++to simulate and analyze a provincial transmission network model,which verifies the correctness of the proposed model and the effectiveness of the algorithm.
