大峡水电站接地系统设计

The Design of Grounding Systcm for Daxia Hydropower Station

大峡水电站接地系统设计是根据电站地理位置，系统中的作用，以及实测的岩石，黄土，水的电阻率，对电站可利用的自然接地体电阻进行计算，依照设计规程对电站接地系统进行设计分析，设计所选用的接地系统满足接地标准及规程要求，能保证人身和设备的安全，保证电站长期安全运行。

This paper deals with the calculation and design of grounding system for Daxia HydropowerStation;According to geographical location,function on electric power system and tested resistivity ofrock,loess and water,this paper calculates the resistance of natural grounding net used by thisstation.Grounding system design conforms to grounding standards and rules and can assure safety ofpeople,equipment and station long-term operation.
