【摘要】：近年来国内发生多起电网事件,事后分析都与省地运行方式安排不当有关。为保证电网安全可靠运行,深入分析了省调度中心与各地区调度中心现有运行方式工作模式的缺陷,将分散在省调和地调的全电压等级在线数据进行统一整合,实现了多时序电网拓扑模型自动拼接。基于全联通遍历算法自动搜索薄弱接线方式并对负荷损失进行精确评估,进而快速识别高危客户供电风险。对实时电网运行控制对策进行省地联合分析,构建了未来电网协同模型并给出不合理重叠检修方式智能排查方法,实现了省地电网联合决策,可用于指导省级电网运行方式协同决策平台建设。通过在省级电网中实际系统的应用表明,提出的策略能有效避免省地运行方式冲突并实现对电网的协同决策。
[Abstract]:In recent years, there have been many power grid events in China, and the post analysis is related to the improper arrangement of the operation mode of the provincial land. In order to ensure the safe and reliable operation of the power grid, the defects of the existing operation mode of the provincial dispatching center and the regional dispatching center are deeply analyzed. The multi time network topology model is automatically spliced. Based on the all connected traversal algorithm, the weak connection mode is automatically searched and the load loss is accurately evaluated, and the risk of power supply is identified quickly. The real-time power grid operation control strategy is analyzed by the provincial joint analysis, and the future power grid cooperative model is constructed and the unreasonable weight is given. The intelligent investigation method of superimposed maintenance mode has realized the joint decision of the provincial and land grid, which can be used to guide the construction of the cooperative decision platform of the provincial power grid operation mode. Through the application of the actual system in the provincial power grid, the proposed strategy can effectively avoid the conflict of the land saving operation mode and realize the cooperative decision to the power grid.
