摘　　要：为解决地面集输管道电伴热工艺热负荷未经核算,导致投资成本和运行成本较高的问题,通过分析不同电伴热敷设方式的传热特性,建立以电伴热系统电费和材料费最小为目标函数的数学模型,结合约束条件与决策变量,对电伴热带的加热功率、缠绕系数和运行时间进行优化设计。结果显示,优化后,加热功率从40 W/m降低至38 W/m,缠绕系数从1.5降低至1.2,日运行时间从12 h降低至10 h,优化后电伴热系统耗电量从315.36×10^(4)kWh降低至199.72×10^(4)kWh,节能减排效果显著。In order to solve the problem that the heat load is not calculated and the investment cost and operation cost are high when the electric tracing process is adopted in the ground gathering and transportation pipeline,the mathematical model is established with the minimum electricity and material cost of the electric tracing system as the objective function by analyzing the heat transfer characteristics of different electric tracing laying methods.The heating power,winding coefficient and running time of the electric tracing zone are optimized combined with constraint conditions and decision variables.The results show that after optimization,the heating power is reduced from 40 W/m to 38 W/m,the winding coefficient is reduced from 1.5 to 1.2,the running time is reduced from 12 h to 10 h per day,the power consumption of the optimized electric heating tracing system is reduced from 315.36×10^(4)kWh to 199.72×10^(4)kWh,and the effect of energy conservation and emission reduction is significant.
