Research on improving power quality of the electric power/uninterrupted power hybrid power supply system

本文通过对市电/不间断电源混合供电系统的电能质量进行数据测试及理论分析,得到混供系统中存在大量容性无功及谐波电流的结论,并在此基础上提出无功补偿和谐波治理的几种有效解决方案,为今后数据中心在采用市电/不间断电源混合供电系统提高供电效率的同时,保证供电系统具备良好的电能质量。

Based on the power quality’s data testing and theoretical analysis of the electric power/uninterrupted power hybrid power supply system,the conclusion is obtained in this paper that a large amount of capacitive reactive power and harmonic currents are appeared in the hybrid power supply system.On this basis,several effective solutions for reactive compensation and harmonics elimination are proposed.These solutions can improve the efficiency under the electric power/uninterrupted power hybrid power supply system for the data center in the future,meanwhile ensure the good power quality of the power supply system.
