摘　　要：针对高压变电站电缆敷设路径优化及其热效应进行了分析。通过建立数学模型,采用改进遗传算法对电缆敷设路径进行优化,同时结合有限元法分析了不同敷设方式下的热效应。研究表明,优化后的敷设路径可显著降低电缆温升,提高系统可靠性。实际工程案例验证,优化方法可有效减少约8%电缆长度,最高温度降低约5℃。这一研究为高压变电站电缆敷设设计提供了理论依据和实用方法。In this paper,the optimization of cable laying path and its thermal effect in high voltage substation are analyzed.The mathematical model is established,the improved genetic algorithm is used to optimize the cable laying path,and the thermal effect of different laying methods is analyzed by finite element method.The research shows that the optimized laying path can significantly reduce the cable temperature rise and improve the system reliability.Through practical engineering cases,the optimization method can effectively reduce the cable length by about 8% and reduce the maximum temperature by about 5 ℃.This research provides a theoretical basis and practical method for the design of high voltage substation cable laying.
