[Abstract]:The sag, wind deviation and galloping of transmission line are the factors that threaten the stability and reliability of power network seriously, which are reflected in the deformation of transmission line. For the above reasons, in order to prevent the harm caused by the sag, wind deviation and galloping of transmission line, it is necessary to monitor the sag amount, wind deviation, galloping track and moving track of transmission line. This is of great significance to the safe operation of power system. In this paper, a high precision real-time monitoring system of transmission line deformation is designed by using differential GPS technology. The main work of this paper is as follows: 1. According to the requirements of high precision real-time monitoring of transmission lines, the performance indexes of the monitoring system are analyzed. Using differential GPS technology, a real time monitoring system for transmission line deformation with ranging precision of centimeter level is designed. In order to realize the scheme of real-time monitoring system based on differential GPS, the design and implementation of peripheral hardware circuit and the programming and debugging of MCU program in the circuit are completed, the system is built and debugged, and the outdoor site test is carried out. The feasibility of the design scheme of the monitoring system is verified. 3. On the basis of verifying the feasibility of the system, the processing method of DGPS output data is designed, after the coordinate system transformation of coordinate data is completed, the measurement data is processed by Kalman filter, and the influence of measurement error is reduced. The measurement accuracy of the system is further improved.
