摘　　要：结合主配一体化智能调度控制系统建设,基于省地县一体化模型中心,完成主电网与配电网模型、数据拼接,建立配电网合环操作在线校核系统。利用该系统进行配电网合环操作可行性分析和风险评估,在线校核系统提供合环稳态电流和冲击电流的计算、环路N-1安全分析和遮断容量扫描等功能,减少合环操作的风险。Combined with the construction of intelligent dispatching and control system for main and distribution network and based on the integrated model center, the main network and distribution network model and data splicing are completed, and online verification system for loop - closing operation of distribution network is established. The proposed system is applied for the feasibilityanalysis and risk assessment of loop - closing operation. The online verification system provides the calculation of loop steady - state current and inrush current, N - 1 safety analysis and breaking capacity scanning, which reduces the risk of loop - closing operation.
