The data detection of overhead power line is mostly disturbed by the field environment,meteorological conditions and other factors.To solve this problem,the sag detection algorithm and inclination sensor are used to calculate the sag between gears,and the positioning detection of the problem power line is realized by CORS system.The system can make the minimum deviation error of voltage compensation reach-0.1,the maximum compensation value of sensitivity coefficient approaches 0.1,and the overall performance is relatively stable.The maximum variation of the data positioning accuracy is more than 80％,and the relative error of the distance from the actual theoretical value is also less than 0.06％.The design of overhead power lines based on CORS system can locate and dynamically monitor the problem lines and sag data,greatly improve the ac-curacy of power monitoring,reduce labor costs and data distortion,and ensure the safe operation of transmission lines.
