岸电接地电阻仿真研究

Simulation on Grounding Resistance of Shore Power

本文根据建筑物接地时常用基础接地极方式减小接地电阻的经验,提出岸电接地装置接地极可以采用基础接地极方式。对基础接地极电阻进行ANSYS仿真计算,通过与垂直接地极电阻理论计算结果相对比,确定基础接地方式的可用性,并得到了码头接地装置和船壳之间不需要连接导体的结论。该研究将对码头接地装置接地极设计提供理论依据,为岸电系统运行安全性提供了保证。

According to the commonly used foundation building grounding way to reduce grounding resistance of experience, the paper puts forward to grounding electrode which can adopt the foundation grounding mode in shore power grounding device. In order to determine availability of the basis of grounding, and by comparing the ANSYS simulation results of the grounding resistance with the theoretical results of the vertical grounding electrode resistance, the paper makes a conclusion that both the terminal grounding device and the hull do not need connecting conductors. The study on grounding electrode of terminal grounding device provides a theoretical basis for design and operation security in shore power system.
