摘 要:传统的变电站监视及巡检方法工作量大、效率低、对经验的依赖度高,已经难以满足日益增长的电网设备巡检需求。鉴于此,本文针对变电站巡检的业务需要,设计了一套具备实时监视、智能巡检、智能联动、智能分析、告警及缺陷管理等功能的智能监视及巡检系统。该系统利用机器视觉技术实现电气设备缺陷智能识别,并采用模型自动更新策略保证识别准确率,能大幅度提高变电站巡检的效率和质量。

Abstract: The traditional substation monitoring and inspection methods have the disadvantages of large workload, low efficiency, and high dependence on experience, and cannot meet the growing demand for inspection of power grid equipment. In view of this, this paper designed a set of intelligent monitoring and inspection system for the needs of substation inspection, which had the functions of real-time monitoring, intelligent inspection, intelligent linkage, intelligent analysis, alarm and defect management. The system uses machine vision technology to intelligently identify defects in electrical equipment, and adopts an automatic model update strategy to ensure recognition accuracy, which can greatly improve the efficiency and quality of substation inspection.
Keywords: intelligent inspection;substation monitoring;model updates automatically
变电站是指电力系统中对电压和电流进行变换,接受电能及分配电能的场所,是电力系统的核心接点,其内部包含电力变压器、高压开关设备、开关柜、二次设备等多种类型的电力设备[1]。为了保障变电站的运行环境安全,保证电力设备稳定可靠运行,需要采用各种方式对变电站内的环境、电力设备进行监视及巡检,以便及时发现问题并处理。目前,我国变电站巡检主要采用传统人工巡检、视频监控、临时检修车的方式[2]。传统的人工巡检方式能发现设备存在的一些异常,但工作量大,技术人员的业务水平、工作经验等主观因素对巡检结果影响较大,不可避免地会出现纰漏[3]。同时,一些可能危害巡检人员人身安全的巡检,还需要停电作业,给用户造成极大困扰。临时检修车方式也面临同样的问题,而且其不能实现对变电站全天候的监测。……
