Selection of Power Supply Mode of Transmission Monitoring Device in Plateau Area Based on Clustering Analysis of Meteorological Parameters

摘要:

在线监测是保障电网安全运行和智能运检的重要手段,不同于变电设备,输电在线监测在交通条件差、运行维护难度大的高原地区作用尤为凸显,但输电在线监测装置电源供电不足及环境适应性差等问题尤为突出,其运行状况高度依赖于线路途经的气象环境条件,因而输电线路在线监测装置电源选择的气象环境判定尤为重要。提出影响高原地区输电线路在线监测装置电源的关键气象环境因子,采用聚类算法实现高原地区气象环境分类,获得高原地区输电线路在线监测装置电源选择的4个典型气象区域,进而提出高原地区输电线路在线监测装置电源供电方式选择的普适性建议,为高原地区输电线路在线监测装置电源选择提供参考。

Abstract:

Online monitoring is an important means to guarantee the safe operation and implement risk control and intelligent operation inspection in large power grid. Unlike substation equipment, the outstanding function of transmission equipment lies in these plateau areas with remote traffic, complex geographic conditions, difficult operation and maintenance management. The adaptability problems of insufficient power supply and long endurance time of monitoring devices are prominent and its operation status highly depends on the environmental and meteorological conditions through which transmission lines pass, so the selection of environmental meteorological judgment is particularly important. The key environmental meteorological factors affecting power supply selection for online monitoring of transmission equipment in plateau area are proposed, and clustering algorithm is used to realize environmental meteorological classification in plateau area. Four typical meteorological regions affecting power supply selection of online monitoring devices for transmission lines in plateau area are obtained. Furthermore, some suggestions on the universality of power supply mode selection of online monitoring devices for transmission lines in each typical meteorological region are proposed, which can provide a reference for power supply selection for online monitoring construction and transformation of transmission lines in those areas.
