Abstract: In order to improve the safety of the training operations on overhead lines, this paper proposes replacing the transformer boosting system in the overhead lines with a resonant boosting system and conducting modeling and simulation analysis using the PSCAD software. The simulation results show that the resonant boosting system has a more stable voltage level and a smaller fault current compared with the transformer boosting system, ensuring the personal safety of the operating personnel. This paper discusses the topological structure of the resonant boosting and simulates the fault current after a human body gets an electric shock, and makes a comparison with the magnitude of the fault current under the same situation of the transformer boosting, highlighting the stability and reliability of the resonant boosting topology.
