摘　　要：为避免因接地故障而引起的电力系统过电压、设备损坏,需要对接地系统进行合理设计,设定合适的接地电流保护阈值。本文对船舶中压交流综合电力推进系统接地故障模式进行了分析,以实船为例,完成了中性点高阻接地装置的选型分析计算和验证。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.
