技术领域
本发明涉及一种基于无线数据APN专网技术的智能监测系统及方法,属于变电监控技术领域。
背景技术:
随着反措要求及运维规程的贯彻落实,变电站直流电源系统的运维管理更趋向于规范化、标准化,特别是对直流电源系统各设备运行状态的监控管理。然而,系统运行情况的掌握仍需要人工巡视,设备信息、隐患管理仍然停留在纸质管理、口头相传的方式下,因此迫切需要通过智能化手段提升直流电源系统运维管理效率。目前尚存以下问题制约直流电源系统运维管理智能化程度的提升。
1、监测各自独立,形成信息孤岛
变电站内直流电源系统各组成部分,包括蓄电池组、充电装置、交流进线、对地绝缘及重要开关等,大都已安装了配套的状态监测装置。然而,各监测装置运行相对独立,相互之间数据无法共享,缺少统一的平台全面管控直流电源系统的运行工况,无法从整体把控站内直流电源系统的安全可靠运行。
2、通信通道难以分配
由于站内设备越来越多,通信通道数量有限,难以为新增的状态监测装置提供数据远传的通道。虽然已有部分直流电源系统运行状态数据虽已上传到调度后台,但运维检修人员无法直接获取,不便于管理;上传数据不全面,且多为单纯的数据展示,未对各类状态信息深度挖掘分析,无法掌握交流进线、充电装置、直流母线、蓄电池、系统绝缘的运行趋势以及健康状态,未实现系统状态监测的价值。
