大型数据中心在国民经济中起到了不可替代的作用，但其繁多的非线性电力负载，如通讯系统、大型计算机、网络控制设备、变频空调、各种数码办公设备、灯光调控系统、UPS、监控系统等给其供电系统带来了严重的谐波干扰，对大型数据中心的运行安全造成了极大的威胁，为此我们分析研究了其谐波产生的根源及谐波的类型和数值，结合实例采用了分层分布式的谐波治理设计方案，取得了良好的效果，解决了大型数据中心的谐波污染问题。
大型數據中心在國民經濟中起到瞭不可替代的作用，但其繁多的非線性電力負載，如通訊繫統、大型計算機、網絡控製設備、變頻空調、各種數碼辦公設備、燈光調控繫統、UPS、鑑控繫統等給其供電繫統帶來瞭嚴重的諧波榦擾，對大型數據中心的運行安全造成瞭極大的威脅，為此我們分析研究瞭其諧波產生的根源及諧波的類型和數值，結閤實例採用瞭分層分佈式的諧波治理設計方案，取得瞭良好的效果，解決瞭大型數據中心的諧波汙染問題。

Large-scale data centers have been playing very important roles in the national economy development. However, severe harmonic disturbance is also brought into the power-supplying due to quantities of nonlinear loads used in the centers, such as communication systems, large-scale computers, network controlling equipments, frequency conversion air-conditions, various digital office instruments, lights regulation systems, UPS, monitoring systems and so on. These disturbances are threatening factors to data centers. Therefore, this article expresses the analysis on the harmonic generating sources, and the types and magnitudes of harmonics; employs layered layout harmonic solving design scheme in a project which gains good effect, and gives a solution for harmonic pollution in large-scale data centers.
