【摘要】：云数据中心(IDC)与高压变电站共站建设时,变电站正常工作时的稳态持续工频磁场和短路时的短时工频磁场可能会威胁共站建设云数据中心的信息存储设备的安全运行。为此,通过分析测量结果及国内外数据,系统总结了高压变电站产生的工频磁场环境的特征,提出了不同电压等级变电站母线、地下变电站、地下电缆、电抗器及电容器产生的稳态持续工频磁场强度最大值分别为64 A/m、45 A/m、49 A/m、4 000 A/m、800 A/m,通过计算分析了变电站工频短路时50 k A短路电流在附近产生的短时工频磁场强度最大值可达2 490 A/m。研究结果表明:在云数据中心建设时,需要控制云数据中心信息设备与电抗器的距离10 m,与电容器的距离5 m,以确保云数据中心信息设备承受的稳态持续工频磁场强度100 A/m;控制云数据中心信息设备与高压母线的距离10 m,可将与变电站共站建设的云数据中心可能出现的短时工频磁场强度降低到1 000 A/m。该研究结果为制定云数据中心与高压变电站共站建设时的工频磁场防护策略奠定了基础。
[Abstract]:In the construction of cloud data center (IDC) and high voltage substation, the steady sustained power frequency magnetic field and the short time power frequency magnetic field during normal operation of the substation may threaten the safe operation of the information storage equipment in the construction of the cloud data center. Therefore, by analyzing the measurement results and domestic and foreign data, the characteristics of the power frequency magnetic field environment generated by high-voltage substation are systematically summarized, and the busbar, underground substation and underground cable of substation with different voltage levels are put forward. The maximum of the steady-state sustained power frequency magnetic field produced by reactor and capacitor is 64 A / m ~ (45) A / m ~ (1) ~ (49) A / m ~ (4) A ~ (4 000) A / m ~ (2 +) ~ (800) A / m, respectively. Through calculation and analysis, the maximum value of 50 Ka short circuit current produced in the vicinity of power frequency short circuit in substation is 2 490 A / m ~ (-1). The results show that: in the construction of cloud data center, The distance between the cloud data center information equipment and the reactor and the capacitor must be controlled by 10 m and 5 m respectively to ensure the steady-state sustained power frequency magnetic field intensity of 100 A / m; to control the cloud data center information equipment and The distance of high voltage bus can be reduced to 1 000 A / m from the short time power frequency magnetic field which may occur in the cloud data center built with substation. The results laid a foundation for establishing the protection strategy of power frequency magnetic field in the construction of cloud data center and high voltage substation.
