架空输电线路温度和最大允许载流量计算
Calculation of temperature and maximum allowable load flow of overhead transmission lines
摘要
Abstract
In allusion to the shortcoming of traditional method which can’t effectively solve the temperature of overhead transmission line and the allowable load flow, a method based on finite element technique is proposed to solve the radial temperature and the maximum allowable load flow of the transmission line. A transmission line temperature field mathematical model and a finite element model of type-JL/LB1A-300/50 aluminum conductor steel reinforced conductor is established, and simulated by ANSYS software under different environmental conditions, which verified that radial temperature difference exists in transmission line, and the radial temperature distribution is influenced by the current-carrying capacity, air convection, light intensity and wind speed etc. The results show that this method can effectively obtain the radial temperature values and allowable load flow of the transmission line in different weather conditions, It is advantageous to improve the safety and stabilityof transmission line, realize the dynamic capacity increase of transmission line and improve the transmission capacity of transmission line.关键词
