摘　　要：为辅助调度运行人员从海量原始电网数据形成调度决策,以实际电网中的自然分区特性为基础,提出了一种电力系统拓扑分区方法,该方法能够对相邻电压等级的变电站进行区域划分。在此基础上,提出了一种面向调度运行的变电站综合风险评估方法,该方法同时考虑到了变电站站内主接线风险、站内设备运行状态风险以及变电站在电网中的整体拓扑风险,其获得的风险评估指标可用于对比不同变电站的综合风险水平,进而为调度运行人员实时操控变电站提供参考数据。最后应用实际电网算例验证了所提方法的正确性和有效性。Based on the partition characteristics in real power systems, a topology partition method is proposed to de- compose the substations with the same voltage into several areas, which can help the dispatchers make decisions based on massive grid data. Then, a composite risk assessment method on substation for dispatching is presented, in which the risks of bus system arrangement, the equipment operation state within a substation and the overall topology of a sub- station in the whole power system are all considered. This composite risk can be used in the comparison analysis among substations, and provide the dispatchers with real-time data. Finally, the correctness and effectiveness of this method are verified in a real power system.
