【摘要】 目前我国输电线路仍以定期检修为主。状态检修(Condition-based Maintenance,CBM)作为一种新发展起来的检修方式,已在电网企业中得到广泛认可和应用。状态检修是根据设备的运行状态来决定是否检修,能够有效和实时的保障设备安全。实现输电线路状态检修,可以减少检修的盲目性、提高输电线路的运行稳定性、节省电网开支、减轻工人劳动强度、促进电力系统信息化的发展。输电线路状态检修工作开展进度远不及发电厂和变电站,针对这一现象,本文提出了提高输电线路状态检修工作效率的三个重要环节,即更客观的状态评价、更准确的预测判断和将输电检修平面从“面”过渡到“点”。针对这三点,设计并开发了一套立体专家系统,分别包括状态评价专家、预测判断专家和计算机处理专家。本文以北京某单位“输电线路在线监测与状态检修系统”项目为依托,搭建了输电线路状态检修的信息管理平台,实现了对线路视频监控信息、绝缘子泄漏电流信息和导线温度信息的可视化管理；将地理信息系统(Geographic Information System, GIS)融入到了输电线路状态检修系统中,实现了监测杆塔优化选址、输电线路台账无纸化查询、污区等级划分和绝缘校验的功能；设计了一种基于层次分析法的输电线路状态模糊评价系统；提出了一种多方法组合的等值盐密模糊预测模型,并将预测结果作为GIS污区划分的主要依据。更多还原

【Abstract】 At present, the main maintenance pattern of transmitting lines is still regular maintenance. As a new developing maintenance, CBM (Condition-based Maintenance) has been widely recognized and applied in the power grid. CBM decides whether to repair or not by equipments’ conditions, and can provides an effective and real-time protection for facilities. Transmitting lines CBM can reduces the blindness of maintenance, improves the running stability, saves expenses, reduces the labor intensity, and promotes the development of information technology of the power system.Transmitting lines CBM is far from power plants and substations. For this phenomenon, three important aspects for improving CBM’s efficiency have been put forward in this paper. These aspects include a more objective state evaluation, a more accurate forecast judgment, and make transmission maintenance flat transform from "surface" to "point". For these three aspects, this paper proposes a set of three-dimensional expert system, including the state evaluation experts, prediction and judgment experts, and computer processing experts.This paper depends on a project named "Online monitoring and condition based maintenance system of the transmission lines" of a company in Beijing, Builds a CBM information management system, which can monitor video information, leakage current and conductor temperature. Pull GIS in transmitting lines CBM information management system, which can optimize the location of monitoring tower, query transmission lines ledger in computer, divide polluted area level and check insulation. Put forward a fuzzy evaluation system based on the Analytic Hierarchy Process for transmitting lines. Promote a multi-method combination fuzzy prediction model for the prediction of ESDD, and use the forecast value as the as the main basis for drawing the polluted area map in GIS.更多还原
