In order to actively promote energy conservation in mobile network, on the basis of strengthening electricity and power management, innovative technological means are adopted to effectively promote energy conservation and emission reduction. Mobile network alone, so far this year, hangzhou unicom has saved 1.6 million kilowatt hour. According to preliminary estimates, mobile networks alone will save more than 3 million kilowatt-hours of electricity in 2010.
The work of energy saving and emission reduction is effectively promoted by implementing the space separation method of base station, energy saving of main equipment, and dormancy transformation of pilot base station switching power supply. Among them, the space separation method of the base station has a significant power saving effect, saving 13% of electricity per station per day on average and about 4000 degrees of electricity per year. This method has low cost and is safe and maintainable. It has been recommended to the headquarters of China unicom group as an innovative solution.In addition, due to the significant effect of the hibernation function transformation of pilot base station switching power supply, 330 sets of zte power supply equipment and 530 sets of Emerson power supply equipment were started to conduct hibernation function transformation, which is expected to save 661,500 kilowatt hours of electricity for the company by the end of the year.
