摘　　要：电磁环网会给电网带来许多的弊端,因此需要在合适的时机打开电磁环网,采取不同电压等级分层,低电压等级电网分区的运行方式。采用粒子群算法,以网络损耗最小、供电能力最大和低电压等级电网划分片区最多为目标函数构建多目标优化模型,对湖北电网的电磁回路进行优化计算,确定3个备选解环方案。然后结合电磁回路解环对电网的影响以及电网正常安全工作的要求,建立电磁回路解环方案评价指标体系。最终运用灰色关联分析法对电磁回路备选解环方案进行分析评估,确定了最合理方案。Electromagnetic loop network will bring a series of drawbacks.It is necessary to solve the electromagnetic loop network to achieve the hierarchical operation and partition running of power grid. The particle swarm algorithm is used and the multi-objective optimization model is established with least network loss and the largest power supply capacity and partition. The optimization calculation is waged and three alternative solutions are given. The evaluation index system of schedule of opening the loop is established.Using the method of grey evaluation to carries out the comprehensive evaluation of the alternative solution,it opens the loop in Hubei power grid and selects the optimal solution of the electromagnetic loop.
