一种快速定位输电线路故障点自动生成推荐计划的方法

A Method for Quickly Locating Fault Points of Transmission Lines and Automatically Generating Recommended Plans

随着电网规模不断扩大和结构日益复杂,其安全稳定运行的压力日益增大,对电网输电智能运维系统也提出了更高的要求。然而,作为主要辅助决策工具的输电智能运维系统并不能完全满足新环境对电网安全运行决策的要求,其应用范围和决策的智能化水平都有待提高。因此,对电网输电智能运维系统的研究具有十分重要的理论和实际意义。首先基于电网调度集控报警事件和保信系统故障信息的多数据源的情况,提出基于完整证据链和继电保护信息模型驱动的双数据源故障诊断新方法,对输电线路跳闸故障进行快速定位。同时综合线路跳闸时刻故障点周围的雷击数据、气象数据、监测终端数据、缺陷和隐患等数据,初步研判线路跳闸故障的原因,自动快速生成故障报告和推荐计划。通过电网运行的实际算例验证各算法的有效性。

The research on the intelligent operation and maintenance system of power grid transmission has very important theoretical and practical significance.This paper firstly proposes a multi-data source situation based on power grid dispatching centralized control alarm events and the information of the trust system’s fault information.It proposes a new dualdata source fault diagnosis method based on a complete evidence chain and a protection information model to quickly locate the transmission line trip fault.At the same time,it integrates lightning data,weather data,monitoring terminal data,defects and hidden dangers and other data around the fault point at the time of the trip to determine the cause of the fault,and automatically and quickly generate a fault report and recommended plan.And verify the effectiveness of each algorithm through actual calculation examples of power grid operation.
