Analysis And Countermeasure Research On The Windage Yaw Accident Of 500 KV Power Transmission Line

Due to the extremely severe weather in recent years, leading to the windage yaw accident of the 500 KV transmission line often occurs, which seriously affects the safe and stable operation of power grid. Therefore, it has become an important task for the line operation and maintenance to carry out the analysis and countermeasure research of the windage yaw accident of 500 KV transmission line.Based on the operation and maintenance of Henan power network, this paper analyzes the windage yaw accident of the 500 KV power transmission line in Henan power network, and puts forward the technical measures of the windage management, and summarizes the relevant experience, and provides reference for the development of the future windage preventive control. The main work included:(1) Study on the basic theory of windage yaw accident in transmission line. Based on the mechanism and influence factors of windage yaw accident of transmission line, the method and the way of solving the windage yaw accident are found.(2) Analysis and Research on the case of transmission line windage yaw accident. In the last five years, the windage yaw accident of the 500 KV transmission line in Henan power grid is analyzed, and the causes of the windage yaw accident are found.(3) Study on the windage preventive technology of transmission line. This paper introduces windage preventive technology, and compares the advantages and disadvantages and scope of the various windage preventive technology, and to assess the effect of some applications.(4) Study on the windage preventive reconstruction in transmission line. Based on the example of the analysis of the transmission line of the windage preventive reconstruction analysis, put forward the control scheme of the windage.
