| Abstract: | In order to avoid overvoltage and equipment damage which caused by grounding fault, it is necessary to design the grounding system reasonably and set the appropriate threshold of grounding current protection. In this paper, the grounding fault mode of medium voltage AC electric propulsion system is analyzed. Taking a real ship as an example, the selection analysis, calculation and verification of neutral high resistance grounding device are completed. |
