山区变电站建构筑物沉降与边坡变形实时自动监测技术应用研究

Research on the application of Real-time automatic monitoring technology of building settlement and slope deformation in substations in mountainous areas

在复杂地质环境中,变电站建(构)筑物沉降和边坡变形监测,是工程建设安全和投产运行安全的关键环节。传统的沉降和边坡监测频率低、人工测量存在误差、及时性较差,无法及时反馈建(构)筑物和边坡的实时状态。基于泉州山区某220 kV变电站,研究了站内配电装置楼、主变基础和挖方边坡的自动化实时监测方案,应用电力物联网技术,通过工程现场部署的边缘物联代理设备,对变电站主要建(构)物及设备基础沉降和边坡位移进行长期、实时、精准的监测及超限预警,提升了变电工程建(构)筑物和边坡的质量水平和施工效率。

In the complex geological environment,the settlement and slope deformation monitoring of substation buildings(structures) are the key links for the safety of engineering construction and operation.The traditional monitoring of settlement and slope has low frequency,large data error and poor timeliness,and cannot respond to timely feedback of the real-time status of buildings and slopes.Based on a 220 kV substation in the mountainous area of Quanzhou,the automatic real-time monitoring scheme of the power distribution device building,main transformer foundation and excavation slope in the substation is studied,and the power Internet of Things technology is applied.Long-term,real-time,accurate monitoring and over-limit early warning of foundation settlement and slope displacement of structures and equipment,to improve the quality level and construction efficiency of substation construction(structure) buildings and slopes.
