Summary: | The article presents the results of the simulation of the electromagnetic effects of an advanced overvoltage traction network on a steel pipeline with a diameter of 250 mm, laid on the earth’s surface. Due to the electromagnetic imbalance of the traction network, at certain points of the structure, voltages with respect to the ground, dangerous for the maintenance personnel, may arise. In such situations, it is necessary to develop measures to improve electrical safety. In the conditions of digitalization of the electric power industry, the solution to this problem should be based on computer technologies that allow determining the induced stresses arising on the parts of pipelines due to the electromagnetic effect of the traction network. The simulation, performed with the help of the Fazonord software package, showed that at a distance of 100 meters from the railway route to the pipeline, the maximum induced voltage at individual points of the structure can reach 100 V, which is more than one and a half times the permissible value. This must be taken into account when designing advanced traction electric power supply systems in the areas where they are close to the main pipelines. |
