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 ef? ciency 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.
