基于层次分析法的输电断面综合监控方法

输电断面是电网安全稳定运行和故障应急处置的重要监控和分析对象，加强输电断面监控水平能够全面把握电网实时运行状态，有效提升电网安全预警能力。为适应电网运行调控需求，研究一种采用以评价目标为指向、以关联指标间的有机组合形成综合评价模块的评价方式，通过德尔菲专家会议方式引入调控运行专家经验对层次分析法进行优化改进，从不同层面反映多元指标与输电断面运行状态的相互关系，实现有针对性的、由点及面的输电断面综合监控。该方法在某区域电网调控中心智能电网调度技术支持系统中得到初步应用，结果表明该方法有效提高了电网输电断面监控水平。

AHP-Based Comprehensive Monitoring Method of Transmission Section

The power transmission section is an important monitoring and analysis object for the safe and stable operation of the power grid and the emergency handling of the faults. Enhancing the monitoring capability of transmission section is helpful to understand the real-time operation of power grid, and effectively improve the early warning ability of power grid security. In order to meet the demand of grid operation dispatching, this paper studies a comprehensive evaluation method of transmission sections based on the analytic hierarchy process (AHP) and proposes the quantitative calculation indicators for the safe operation of the transmission sections; The Delphi method is introduced to make full use of the experience of operation dispatching experts to improve the AHP, so as to reflect the relationship between the multiple indexes and the operation state of the transmission sections, and achieve a comprehensive monitoring of the transmission sections. This method is applied in the control center of a regional power grid, and the results show that this method can effectively improve the monitoring capability of power transmission section.
