摘　　要：为分析我国750kV双通道(2个平行单回路架设)交流输电线路对邻近输油输气管道的电磁影响,利用CDEGS软件对邻近某750kV交流输电线路的输油输气管道的电磁环境进行了系统的仿真研究。参考国内外相关标准,提出适用于我国交流输电线路对邻近输油输气管道电磁影响的限值建议,并针对输电线路不同运行工况,计算分析了输油输气管道上的干扰电压。通过仿真计算结果与相关限值的比较,分析和评估了750kV双通道交流输电线路对输油输气管道的电磁影响程度,并提出防护措施建议。In order to study the electromagnetic influence of 750 kV double-circuit （ consisting of two parallel single circuit） AC transmission lines in China on nearby petroleum ＆ gas pipelines, the electromagnetic environment of the petroleum ＆ gas pipeline nearby a 750 kV AC transmission line was simulated by using a software of CDEGS. Based on the domestic and international standards, the limits of the electromagnetic influences of AC transmission lines on nearby petroleum ＆ gas pipelines were proposed, and the interference voltage of the pipelines were calculated and analyzed under different operating conditions of AC transmission lines. Through the comparison of the simulation results and the limits, analysis and assessment were performed on the degree of electromagnetic influences of 750 kV double-circuit AC transmission lines on petroleum ＆ gas pipelines, and some protective measures were suggested.
