Research on inclination monitoring method of transmission tower based on satellite positioning technology

为保障应用电网运行环境的稳定,解决因输电杆塔倾斜行为而造成的大面积停电问题,提出基于卫星定位技术的输电杆塔倾斜监测方法。通过GPS节点协调的方式,建立完整的同步时钟模式,联合定位精度因子,研究了卫星定位技术的非线性问题。在此基础上,分析输电线路杆塔的连接结构形式,利用位移载荷量计算结果,对监测系数进行标定处理,完成输电杆塔倾斜的监测。对比实验结果表明,新型监测方法可在10°~80°的倾角环境中得到准确的倾斜定位结果,且TID指标水平也远高于传统伪卫星监测手段,满足合理保护应用电网运行环境稳定的实际应用需求。

In order to ensure the stable operation environment of power gridand solve the problem of large-scale blackout caused by the tilt behavior of transmission tower,a monitoring method of transmission tower tilt based on satellite positioning technology is proposed.Through the way of GPS node coordination,a complete synchronous clock mode is established,and the positioning accuracy factor is combined to realize the nonlinear problem research of satellite positioning technology.On this basis,the connection structure of transmission line tower is analyzed,and the monitoring coefficient is calibrated by using the displacement load calculation results to complete the monitoring of transmission tower tilt.The experimental results show that the new monitoring method can get accurate tilt positioning results in 10°~80°tilt environment,and the TID index level is much higher than the traditional pseudolite monitoring method,which can meet the practical application needs of reasonable protection and application of stable operation environment of power grid.
