[Green communication products lead the new trend of energy saving] lead the new trend of the times

Recently, the Ministry of Industry and Information Technology issued the Notice on the Key Points of Energy Conservation and Comprehensive Utilization of Industry and Communication Industry in 2009, which once again emphasized that energy conservation, consumption reduction and emission reduction should be taken as an important starting point to cope with the financial crisis, maintain growth, adjust structure and promote development, accelerate enterprise progress and technological transformation, and promote the in-depth development of energy conservation and emission reduction. In terms of technological innovation to promote energy conservation and emission reduction, Guangdong Mobile tries first, constantly innovates technology to promote energy conservation in the industry, and contributes to creating a green wind in the industry.

The energy-saving effect of storage battery is remarkable.

Batteries are widely used in mobile communication equipment. If technological innovation can be carried out, the energy-saving effect will be immeasurable. A few days ago, Guangdong Mobile's innovative battery charging "dynamic planning" technology experiment was successful in Guangzhou Xide Shengji Building. This technology enables the power monitoring system to dynamically set the time point and module current limit of battery subsection charging according to different power outage duration, battery capacity, model configuration, load, etc. It realizes the scientific centralized dispatching of power system, effectively suppresses the stable peak current of the battery from charging to initial charging of rectification, and greatly improves the safety and reliability of power supply system charging.

At present, the battery charging power consumption of Shengji Building in West Germany has been reduced to 30%, which is equivalent to saving about 3.45 million yuan in expansion and renovation costs, providing a steady stream of green electricity for the operation of the building.

Base station enters the era of green energy saving.

Energy saving and consumption reduction of base stations has always been one of the concerns of telecom operators. In order to solve this problem, Guangdong Mobile innovatively developed the integration method of cess technology based on harmonic filtering and reactive power compensation, which has obvious energy-saving effect and led the new trend of green energy-saving for base stations.

Cess technology is a comprehensive energy-saving technology integration. Through the transformation of physical energy-saving technology and traditional electronic energy-saving technology, neutral waves and currents in the loop can be effectively released, thus improving the conductivity and equipment efficiency. The pilot data of this technology in four stations, such as Zhaoqing Dayong Base Station, show that this technology can save electricity by 1 1.06%, and a single station can save electricity by 4645.20kWh a year. According to the calculation of 3 kWh generated by 1 kg standard coal, the coal resource demand can be reduced by about 1.5 tons. In addition, the payback period of this technology is less than two years, and the service life of technology integrators is more than 20 years. According to the normal service life 10 year, a single station 10 year can save about 35,000 yuan. According to the calculation of 800 base stations in Zhaoqing area, 10 can save 27.85 million yuan, and the economic benefit is very obvious.
