摘要

中压电力系统中性点接地方式的选择是一个综合性的课题，它关系到系统的供电可靠性和用电安全。本文通过Matlab仿真建立了船用中压电力系统模型，分析比较了中性点不接地、中性点电阻接地和中性点消弧线圈接地三种模式下单相接地短路故障的特点。在此基础上，结合某工程船舶的实际情况，根据接地装置参数的整定方法，计算出接地电阻值。结果表明，在船舶中压电力系统中采用高电阻中性点接地更为合适。

Simulation Study on Neutral Grounding Mode of Marine Intermediate Voltage Power System

The selection of neutral grounding mode in intermediate voltage power system is a comprehensive topic, which is closely related to the reliability of power supply and electrical safety of the system. In this paper, the marine intermediate voltage power system model is established by Matlab simulation, and the characteristics of single-phase grounding short circuit fault in three modes, namely neutral point ungrounded, neutral grounding by resistance and neutral grounding by arc suppression coil, are analyzed and compared. On this basis and combined with the actual situation of a certain engineering ship, the ground resistor value is calculated according to the setting method of grounding device parameters. The results show that it is more suitable to use neutral grounding through high resistor for marine intermediate voltage power system.
