Abstract
Due to the electric power industry and oil and gas industry have a close principle to the preferential transmission route. The electromagnetic impact of power transmission line is increasingly prominent. To explore the electromagnetic effect of electric power line on the multi buried metal pipeline, the mechanism of the electromagnetic effect of the AC transmission line to the oil gas pipeline is analyzed and the simulation model of the electromagnetic effect of 750kV AC line to the multi buried oil gas pipeline is built in the electromagnetic simulation software CDEGS, which is based on the method of moments. Aim at Qiaowan 750kV AC transmission line, the paper analyzed the electromagnetic effect of the power frequency current, single-phase short-circuit fault current and the lighting current on the oil gas pipeline. At last, the influence of the interference voltage of the 750kV AC transmission engineering to the buried oil gas pipeline is obtained and the shortest safe distance from the tower and underground pipelines and related protection measures is put forward.
