When renewable resources become a new approach to energy-saving and emission reduction in the communications industry, new energy base stations, including solar base stations, wind energy base stations, and wind-solar hybrid base stations, are doing their utmost to help exchange information in special regions.
In remote areas where electricity is not available and where sunshine or wind power is abundant, new energy base stations are more suitable than traditional base stations.
At present, the communications industry in China has built more than 10,000 base stations for new energy, such as wind and light, and China Mobile has built more than 9,000 base stations. However, China Unicom and China Telecom have all stepped up their efforts to build new energy base stations in the southwest and northwest regions. A wave of new energy booms is sweeping the country.
Solar base stations link snow-covered plateaus to Tibet, the world’s closest region to the sun has ushered in a “revolution†brought about by the sun. Thousands of solar base stations are bringing “light†to the roof of the world.
As we all know, the ecological environment in Tibet is very fragile, and once it is destroyed, the recovery cycle is very long and the natural conditions are poor. This results in multiple difficulties for the power grid construction, such as large investment, long lines, and difficult construction. Therefore, power construction has been lagging behind. It is understood that due to power supply factors, China Mobile only built more than 200 mobile communication base stations between 2000 and 2005, and the coverage of the network in townships was even less than 30%.
However, the area with the highest average altitude in the world has rich and stable solar energy resources. The abundant solar energy has laid a natural foundation for the Tibetan communications to get rid of the shackles of the city's power construction. Since 2005, Tibet Mobile has decided to vigorously develop off-grid solar power plants and promote the construction of communication base stations. By the end of 2008, 683 townships in Tibet had achieved full coverage.
After more than five years of perseverance, China Mobile has built more than 2,000 solar base stations in Tibet, making Tibet the largest solar base station group in the world. It is worth mentioning that in the world’s highest Everest, the worst climate in the world, Tibet Mobile also built solar mobile base stations in areas of 5,200 meters, 5,820 meters and 6,500 meters above sea level in 2007 to achieve full network coverage of mountaineering routes. At present, China Mobile has built more than 2,000 solar energy base stations in Tibet and has become the world's largest solar base station group.
If you don’t go to Tibet in person, it is difficult to realize how difficult it is to build on a snowy plateau, how bad the environment is, how hard the conditions are, and how great the investment is. According to statistics, in Tibet, each solar base station will have an investment of about 1 million yuan, of which about 60% will be invested in solar energy equipment. Although the investment is large, the relevant person in charge of the Tibet Mobile Network Ministry stated that after the “labor pains†of the previous period, solar base stations have begun to show unparalleled advantages in Tibet.
On the one hand, the electricity cost of solar base stations is zero. Compared with ordinary communication base stations, an ordinary communication base station consumes about 3,600 degrees per year, and it needs electricity costs of nearly 50,000 yuan. On the other hand, the solar base station's electricity bill is zero, and the minimum service life is five years. Only the electricity bill will save 216,000 yuan.
On the other hand, solar base stations also have great advantages in energy conservation and emission reduction. It is understood that a solar energy supply system with a capacity of 1 million watts can generate 1.57 million kWh per year. Compared with coal-fired power plants with the same capacity, it can save 550 tons of standard coal, 11.6 tons of sulfur dioxide emissions, and 1813 tons of carbon dioxide emission reduction. , smoke reduction 135 tons.
At the same time, Tibet Mobile has made persistent efforts to pilot the application of solar integrated repeater equipment. The advantages of such equipment in energy conservation and emission reduction are even more prominent, and the power consumption of the equipment is also lower.
Compared with solar base stations, wind energy base stations reported that wind energy base stations are another option for operators to solve the problems of base station construction and realize energy conservation and emission reduction.
The advantage of the wind energy base station is that the wind power generation system accesses the original power supply system of the base station by directly connecting to the open circuit of the rectifier output. When there is wind resource, every degree of power generated by the wind power system will be preferentially used by the base station load. The original rectifier will reduce or even stop the output; when the wind resource is insufficient or not, the rectifier will increase the output current until it meets the load demand.
At present, China Mobile Zhejiang has successfully used the base station resources for the pilot work of wind power generation, and wind energy base stations have been further promoted in Zhejiang Province. At present, Zhejiang, Ningbo, Taizhou, Zhoushan, Wenzhou, Jiaxing and other coastal areas have abundant wind energy resources, and natural conditions around the country are more suitable for installing wind power systems. These regions mainly use existing tower resources and install wind turbines to solve the problems of remote base stations with relatively unstable power supply and high maintenance costs, while achieving the goals of energy-saving emission reduction and green base stations.
Taking the current remote base station load current as 10A as an example, it is estimated that each base station can save 1,800 kWh per year after implementing wind power generation according to the wind power generation system operating for 5 months per year.
"Landscape" is boundless. In 1997, Africa and Namibia, a country with even worse natural conditions, the world's first base station combining wind energy and solar energy was built here. Since then, the wind energy and energy-capable base stations have taken root.
When the Tibetan people chose a solar base station as their platform for receiving information, they started to gradually adopt wind-solar hybrid base stations in some areas where the environment is different but equally bad, and established new information through the complementary satellite base station solutions. ".
Qinghai, one of the most important Qinghai-Tibet Plateau provinces, is where the “throat†of the Silk Road is located. It is a typical plateau continental climate. The sunshine duration exceeds 3,000 hours a year, exceeding the sunshine time of nearly 700 hours in the same latitudes. It is not inferior to Tibet. At the same time, the high winds and sandstorms in Qinghai Province, located in the Qaidam Basin, although the climate is harsh, but it also brings abundant wind energy. It is under such conditions that the new energy base stations with complementary scenery are in Qinghai Province. Wide spread.
It is reported that Qinghai Mobile has introduced a number of new technologies and new processes to reduce construction costs and save network operating costs. During the construction of the Qinghai-Tibet Highway, Qinghai Mobile made great contributions to ensuring the smooth communication along the Qinghai-Tibet line.
A total of 53 base stations are covered along the 630 km range of the Qinghai-Tibet line, of which 28 use 4 to 7.5 kilowatts of solar or wind power. The solar power supply has no emissions, and it is 100% pollution-free and energy-saving and emission-reducing. At the same time, the traditional base station construction plan for the Qinghai-Tibet line is expected to consume 660,000 kWh of electricity a year, which will require about 726,000 yuan of electricity, while the wind-solar hybrid base stations will use green energy such as solar energy and wind power to supply power to the base station in large scale. Save at least 72 million yuan in electricity bills and reduce CO2 emissions by 650 tons.
While the new energy base stations with complementary scenery are moving forward in Qinghai Province, the new energy base stations with “wind, light, and water†complement each other are being constructed in the Hainan Tibetan Autonomous Prefecture of Qinghai Province. It is reported that the Yellow River is located in the Hainan Province of Qinghai Province. The hydropower reserves of the main stream amounted to 9.94 million kilowatts. It is planned to develop 16 cascade hydropower stations with an installed capacity of more than 9 million kilowatts. During the “Twelfth Five-Year Plan†period, Hainan State plans to add 3000MW of photovoltaic construction scale and wind power installed capacity of 2050MW. The development of wind-optical-water complementary power generation model in the state will help the local grid securely, economically, and stably.

Advant Master is a widely installed and actively supported ABB DCS. It is used by many customers that plan to stay on the platform for several years to come. A majority of customers have enhanced user experience by adding the System 800xA HMI to their Advant systems controllers and I/Os.
Released in 1992, Advant Master DCS was the result of the development of a common hardware and software platform for evolving the ABB Master and Taylor MOD 300 systems.
Advant Master DCS introduced two high capacity controllers, AC450 and AC410, and the S100 rack mounted I/O featuring an improved redundancy scheme, along with a state of the art operator interface, based on UNIX workstations. In 1996 the S800 remote I/O was launched, providing modular flexibility with redundant communication and a 1ms time stamp.
The predecessor to Advant Master DCS, ABB Master, was introduced in 1984 based on MasterPiece 200 controllers with the rack mounted S100 I/O along with the MasterView 800 operator interface with high end Tesselator Display system, further adding remote S400 I/O in 1988. Remote EX S800 I/O and Profibus DP support for connection to third party sub systems was released in the late 1990s.
