摘　　要：工业领域中应用在机械自动化、电气自动化等方面的变频器,如今也在数据中心冷冻水系统中大量使用,特别是系统中冷冻水泵、冷却水泵采用变频器供电更适合系统的整体控制。与此同时,变频器的谐波危害也对冷冻水系统的正常运行带来威胁。通过对谐波产生的分析,针对性地提出了可减少谐波的几个手段,为“东数西算”算力枢纽机房基础能源建设探索一条供电运行更安全、系统管理更精益、整体节能更深入的新途径。The frequency converters used in mechanical automation and electrical automation in the industrial field are also widely used in the chilled water system of the data center.In particular,the chilled water pump and the cooling water pump in the system are powered by frequency converters,which are more suitable for the overall control of the system.At the same time,the harmonic hazard of the frequency converter also threatens the normal operation of the chilled water system.Through the analysis of harmonic generation,several means to reduce harmonics are put forward,and the basic energy construction of the computing power hub computer room of"East Numbers and West Calculations"is explored for a safer power supply operation,leaner system management,and better overall energy saving deep new way.
