摘要
为提高±500kV伊穆直流接地极址运维智能化水平、及时掌握接地极的运行状况、提高直流工程的安全性,提出并实现了±500kV伊穆直流接地极址在线监测系统。该系统前端监测单元能够实时监测温湿度和接地极入地电流,同时对现场环境进行视频监测;通过远距离无线数据传输,将前端监测到的数据反馈到后台控制系统;后台控制系统将硬件系统采集的各种数据经过计算以合理的方式显示供操作人员参考,并进行状态诊断和故障自动报警。
In order to enhance the intelligence level of =k 500kV DC grounding Yimu electrode maintenance, grasp the operation condition of the electrode, and improve the security of HVDC project, on-line monitoring system of 500 kV Yimu DC ground electrode is proposed and implemented. Front-end monitoring unit is capable of real-time monitoring of temperature, humidity and grounding current. Meanwhile, it can realize video monitoring of the site environment. Through the long-range wireless data transmission, the front-end monitoring data are fed back to the background control system. These data collected by hardware system are calculated and displayed in a reasonable manner for operator＇s refer- ence, state diagnosis and fault alarm automatically.
