【摘要】：云数据中心占地面积巨大、电能需求也巨大,需要与配套的变电站共址建设,两部分接地网之间的相互影响和连接方式是云数据中心设计中需要考虑的重点问题。以某实际云数据中心与变电站共址为例,建立电磁场数值计算模型,通过仿真计算研究不同接地连接方式时,变电站与数据中心的地电位、接触电位差、跨步电位差等的分布,提出经济合理的均压措施。经过分析可知,当云数据中心与变电站接地网分别独立布置时,变电站接地网与其他接地网之间形成了较大的电位差,影响人身和设备安全。建议各接地网相互紧密连接,从而在各接地网之间获得良好的均压效果,保证人身和设备安全。
[Abstract]:The cloud data center occupies an area of huge area and needs huge electric energy, which needs to be co-located with the matching substation. The interaction and connection between the two parts of grounding grid are the key issues to be considered in the design of the cloud data center. Taking a practical cloud data center and substation as an example, a numerical calculation model of electromagnetic field is established. The distribution of ground potential, contact potential difference and stride potential difference between substation and data center are studied by simulation. The economic and reasonable pressure equalization measures are put forward. Through the analysis we can know that when the cloud data center and the substation grounding network are arranged separately there is a large potential difference between the substation grounding network and other grounding grids which affects the safety of the person and equipment. It is suggested that each grounding grid be closely connected with each other so as to obtain a good voltage sharing effect between the grounding grids and to ensure the safety of personal and equipment.
