Abstract: The wind speed used in overhead conductor temperature calculation is usually measured near to ground. The low precision of the measurement leads a large deviation in temperature calculation, resulting high difficulty in line operation and maintenance. To overcome this problem, a temperature calculation method of overhead conductors based on elevation wind speed prediction is proposed in this paper. Taylor formula iteration method is used in the calculation process to realize the fast and accurate calculation of wire temperature. Integrating the finite element method with the basic heat transfer principles, the temperature of overhead conductors is simulated in ANSYS, and the simulation results prove the reasonableness of the proposed method. Finally, the practical application results verify its effectiveness.

Key words: conductor temperature, elevation wind speed prediction, finite element method, temperature filed model, Taylor formula iteration method
