Research of the Electromagnetic compatibility problems caused as putting heavy and weak current facilities together in the subway system

摘要

Based on CST, models of the heavy current facilities in the subway system have been built and the simulation has been completed to acquire the radiation of EMI. By comparing the results of the simulation with the corresponding results of the actual measurement, the models are modified until the simulation of the models could mainly reflect the situation of Electromagnetic field around the heavy current facilities correctly. With the procedure of actual measurement, modeling, simulation, analysis and modification, the shortest distance between the heavy and weak current facilities in the subway station in the normal working condition could be proposed. A more reasonable layout of all facilities could also be acquired so that the resource of the rooms could be saved and the administration of the whole station could be easier.
