October 15, led by the China Electric Power Research Institute led the State Grid Corporation of science and technology project "Transmission and Distribution Line against strong winds key technology research and application of" passed the inspection. Acceptance experts agree that the project completed the contractual content of the study, a number of research results reached the international advanced level, will provide strong technical support for the construction and operation of wind power grid. China has the characteristics of a wide range of strong winds and many types of strong winds. Especially in the inland areas along the southeast coast and Xinjiang, there are annual strong wind disasters that threaten the safe operation of power grids. Wind disaster prevention and control is one of the important fields of disaster prevention and reduction of power grid. The key technologies such as failure modes and countermeasures of transmission and distribution lines under strong wind disasters, wind-proof design parameters of transmission and distribution lines, anti-strong wind technology, and value of clearance of transmission lines in rainfall environment are Problems to be solved in power grid disaster prevention and control. The project put forward the countermeasures and technical measures for strong wind disaster of transmission and distribution lines, which is of great significance for improving the comprehensive ability of transmission and distribution lines to resist the strong wind disaster and for enhancing the safe and stable operation of the power grid. The results of the project typhoon and downstream typhoon wind load calculation method and tower structure design method to make up for the current lack of regulations for unconventional wind power transmission line design is proposed by the use of a word plate, a single bolt After the reinforcement, the bearing capacity of the main material can be increased by 50% or more, forming the Technical Guidelines for Anti-strong Wind Design of Overhead Distribution Lines (draft for approval), which can be used for design of distribution lines in strong wind areas Provide theoretical basis and technical reference. At present, the lightweight high strength concrete pole developed by this project has been piloted on the 10 kV distribution line along the coast of Zhejiang Province and has been in good condition after being tested by the strong typhoon cycle in 2014 and 2015. The results of the project will be applied to a large area of ​​distribution lines in coastal areas, significantly improving the ability of coastal distribution lines to resist typhoon and operational reliability.
