【摘要】：云數(shù)據(jù)中心(IDC)與高壓變電站共站建設(shè)時(shí),變電站正常工作時(shí)的穩(wěn)態(tài)持續(xù)工頻磁場和短路時(shí)的短時(shí)工頻磁場可能會(huì)威脅共站建設(shè)云數(shù)據(jù)中心的信息存儲(chǔ)設(shè)備的安全運(yùn)行。為此,通過分析測量結(jié)果及國內(nèi)外數(shù)據(jù),系統(tǒng)總結(jié)了高壓變電站產(chǎn)生的工頻磁場環(huán)境的特征,提出了不同電壓等級(jí)變電站母線、地下變電站、地下電纜、電抗器及電容器產(chǎn)生的穩(wěn)態(tài)持續(xù)工頻磁場強(qiáng)度最大值分別為64 A/m、45 A/m、49 A/m、4 000 A/m、800 A/m,通過計(jì)算分析了變電站工頻短路時(shí)50 k A短路電流在附近產(chǎn)生的短時(shí)工頻磁場強(qiáng)度最大值可達(dá)2 490 A/m。研究結(jié)果表明:在云數(shù)據(jù)中心建設(shè)時(shí),需要控制云數(shù)據(jù)中心信息設(shè)備與電抗器的距離10 m,與電容器的距離5 m,以確保云數(shù)據(jù)中心信息設(shè)備承受的穩(wěn)態(tài)持續(xù)工頻磁場強(qiáng)度100 A/m;控制云數(shù)據(jù)中心信息設(shè)備與高壓母線的距離10 m,可將與變電站共站建設(shè)的云數(shù)據(jù)中心可能出現(xiàn)的短時(shí)工頻磁場強(qiáng)度降低到1 000 A/m。該研究結(jié)果為制定云數(shù)據(jù)中心與高壓變電站共站建設(shè)時(shí)的工頻磁場防護(hù)策略奠定了基礎(chǔ)。
[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.
