The sight of the plateau is increasing day by day, and the high-quality power grid has injected abundant power into the leap-forward development of Tibet.
Here are some special stories to show you the United, prosperous, civilized, harmonious and beautiful socialist modern new Tibet.
A special road—
Diantianlu
In April, Linzhi is in Bomi, surrounded by clouds, with green hills like Dai and peach blossoms in full bloom.
"Let's go! Let's start as soon as possible! " Employees of Tibet Electric Power EHV Company packed their equipment and rushed to the inspection site.
"This is my first time to take part in a helicopter cruise!" He, who has been participating in the investigation of the networking project between Tibet and China since 20 18, said excitedly. His cruise missions this time include 500 kV Dagu Hydropower Station to Xu Mu Substation, Bomi to Linzhi and Zuogong to Bomi. The operation started in Chacha, Shannan, and ended in Zuogong, Qamdo, with a total length of 1.900 km and an average elevation of more than 3,800 meters.
From March 15, State Grid Tibet Electric Power Joint Network Navigation Company conducted cooperative inspection and navigation of helicopters and drones for the Tibet-China networking project. This is another experience accumulation for State Grid Tibet Electric Power to deepen the new mode of "three-dimensional inspection+centralized monitoring".
The average elevation of Tibet Zhonglian network project is more than 4000 meters. The backbone line crosses the core area of Hengduan Mountains and the hinterland of Qinghai-Tibet Plateau, crossing Lancang River, Nujiang River and Yarlung Zangbo River 10 times. The difficulty of operation and maintenance can be imagined when crossing areas such as low pressure, lack of oxygen, severe cold, strong wind and strong radiation. Air "Iron Eagle" escort can not only save time and reduce risks, but also greatly improve efficiency.
"We can complete at least 40 kilometers of transmission line inspection in one sortie, and the efficiency is dozens of times that of traditional manual inspection." He introduced that helicopter inspection has the characteristics of flexibility, heavy load, long battery life, no terrain restrictions and high work efficiency. The aerial work mode can also hover at an altitude of 5500 meters.
The networking project between Tibet and China is one of the four "electric highways" in Tibet.
From 20 10 to 2020, more than 654.38+million electric power builders braved the severe cold, snowstorm and lack of oxygen during the war, and set up four "electric power roads" on the roof of the world, connecting Qinghai-Tibet, Sichuan-Tibet, Tibet-China and Ali.
20 1 165438 February, the Qinghai-Tibet interconnection project was completed and put into operation, and the long-term isolated operation history of Tibet power grid was completely ended, and it was interconnected with the state grid for the first time;
On October 20 1 14 10, the Sichuan-Tibet interconnection project was completed and put into operation, and the Qamdo power grid in Tibet was connected to the Sichuan power grid.
On October 20 18 165438 10, the power grid project in Tibet was completed and put into operation, and the power grid in Tibet was connected with Changdu power grid and Sichuan power grid, and Tibet entered the era of 500 kV UHV power grid.
From June 5438 to February 2020, Ali Interconnection Project was completed and put into operation, and Tibet Power Grid entered a new era of unified power grid in the whole region.
The completion and commissioning of the four "Power Sky Roads" marks the further smoothness of the energy channels and hubs with electricity as the core in the Qinghai-Tibet Plateau, which not only greatly relieves the long-standing contradiction of power shortage in Tibet, but also lays a solid foundation for the transformation of resource advantages into economic advantages and development advantages in the whole region.
Helicopters, unmanned aerial vehicles and increasingly advanced operation and maintenance technologies ensure the safe and stable operation of energy channels.
During the "Thirteenth Five-Year Plan" period, under the direct pull of four "power antenna lines", the highest power load of Tibet power grid set a new record year after year, with an average annual increase of nearly 20%, reaching 6.5438+0.7 million kilowatts; The electricity consumption of the whole society reached 8.25 billion kWh, maintaining double-digit growth for many years.
Tibet Power Grid also actively participates in national power balance and trans-regional power transactions. By the end of 20021,the cumulative transportation of clean energy such as hydropower exceeded 9.2 billion kwh, which directly promoted the economic growth of the whole region by 2.43 billion yuan and reduced the carbon dioxide emissions of the Qinghai-Tibet Plateau by 9172,400 tons.
Silver dragons dance in the wind, and the plateau is greener. At present, Tibet has formed a comprehensive energy system with hydropower as the mainstay, supplemented by solar energy, wind energy and geothermal energy.
Snow plateau, in addition to the iconic white, under the goal of "double carbon", green is also becoming a new fashion. Tibet's first plateau airport shore power project was put into operation at Gongga International Airport in Lhasa, and the world's highest pure electric heavy truck power station project was completed at Yulong Copper Mine in Changdu. Charging piles were continuously built along the Sichuan-Tibet Highway and connected to the smart car networking platform of the State Grid. More and more people chose to drive new energy vehicles to travel in Tibet. ...
A special team—
Living working class
After graduating from Lin Zhao University in 2065 438+08 1995, the little girl came to Lhasa Power Supply Company to take a course on live working and power protection. In 2020, she officially became a live operator and the first female employee of State Grid Tibet Power.
Wearing thick insulating clothes and holding heavy insulating tools, working with electricity in plateau environment requires higher physical strength.
Lin Zhao, who weighs only 80 kilograms, exercises his arm strength with two buckets of water every day to make up for his lack of physical strength. Now, when she is working live, she is skilled in movements and standardized in procedures. "I thought it would be difficult at first for 40 minutes of homework, but when I really concentrate on my work, the time seems to be shortened." Lin Zhao said.
Lin Zhao's success is inseparable from the help of the whole team. Lhasa Power Supply Company Urban Power Supply Service Center Live Working Power Protection Class is the first team of State Grid Tibet Power to perform live working. Her master Zhaxi Nima is the first person to work at high altitude in Tibet.
Since 2065438+July 2006, the team has realized live working for the first time in Tibet 10 kV distribution network, and actually carried out live working for more than 700 times.
At present, the number of people who have obtained evidence for uninterrupted operation of State Grid Tibet Electric Power has reached 85, and 1458 uninterrupted operations have been carried out. The uninterrupted operation rate of the distribution network reached 35%, with an additional power supply of 4.259 million kWh, reducing the number of blackouts by 98,726.83 hours. The reliability rate of urban power supply in Tibet reached 99.73%.
Reliable power supply can reassure enterprises and make economic development more emboldened.
"The temperature here is low all the year round, the air is dry and the sulfur dioxide content is low, which has the natural advantage of attracting our investment." Jiang Ning, president of Tibet Ningsuan Technology Group Co., Ltd. said. The largest cloud computing data center in Tibet owned by the Group is located in Lhasa High-tech Zone. After the completion of the third phase of the project, the annual operating income will reach10 billion yuan.
Not far away, another data center has also sprung up. Pingcuo Tenzin, head of electromechanical engineering of the first phase project of China Mobile's Lhasa data center in Tibet, said that the project requires very high reliability of power supply, and the power supply company came to study the power supply scheme with the project party very early, and specially planned two main power supplies and two standby power supplies.
A modern town—
Senbury wisdom energy townlet
Once poor households, now they not only live in new houses, but also live more "wisdom".
In the southern Tibet Valley and the north bank of the Yarlung Zangbo River, the relocation and resettlement site of Senbury in Shannan City is the first smart energy town in Tibet. Around New Year's Day in 2020, 4,058 herdsmen from extremely high altitude areas 13 villages moved here.
Talking about today's beautiful life, Solang Dunzhu, the account manager of Sembri Smart Power Supply Business Hall, smiled: "We have moved into a new home, found a job and lived a smart life."
After moving, he bought a lot of household appliances, and the sockets at home are all intelligent and can be controlled on the mobile phone. "I never thought electricity could be so convenient." Solang Dunzhu said, "Solar photovoltaic panels on the roof can also bring about income in 6 yuan every day." His mother often said that now he lives in a bright and tidy house, with stable family income and convenient medical treatment. Compared with his time in pastoral areas, the whole person's spirit is much better, thanks to the good policies of the party and the government.
In order to help the relocated people increase their income steadily, Shannan Power Supply Company built a distributed photovoltaic power generation project on the roof of Sembrian's home. The company also installed electric heating facilities for the relocated households' homes, hospitals and local primary school dormitories.
Shannan Power Supply Company regards "I do practical things for the masses" as an important part of the study and education of Party history, and built new transformers 15 and 9 ring network cabinets for the first phase resettlement project, and reconstructed 10 kV lines for 5.4 kilometers. In the second phase of resettlement project, 34 transformers and 20 ring network cabinets were built, and 37.5 kilometers of 10 kV cable lines were reconstructed to provide power supply services for the high-quality development and construction of cities and towns.
Roof photovoltaic increases their income, and reliable electricity provides sufficient kinetic energy for the development of local industries. In the past two years, farmers and herdsmen in Samburji have lived in new houses, obtained jobs and income, and achieved a great leap from immigration to settlement and from settlement to happiness.
It's not just the town of Samburji. On the snowy plateau, every household lights up a steady and bright lamp, and the poor counties and towns change their backward faces, and happy smiles bloom brightly.
The Pingcuo pea vermicelli processing professional cooperative in Song Ke Village, the first village of democratic reform in Tibet, used a full set of electrified equipment, and the daily output of vermicelli increased from 200 kg to 2,000 kg. Jizhaogu Cooperative in Tangchen Town, Ding Jie County has newly purchased an electric packaging machine, hoping to receive more online orders. The production line of Langdun Walnut Professional Cooperative in Langxian County is running at full capacity, and the quality of walnuts can be controlled more accurately after electrification upgrade. ...
Electricity is abundant, industry is thriving, and life is more promising.
On February 25th, 20021year, the Tibet Electric Power and Rural Power Work Department of State Grid won the honorary title of "National Model in Fighting Poverty" at the summary and commendation meeting of the national fight against poverty, which is the best praise for the State Grid Corporation to help win the fight against poverty.
Over the past year, State Grid Tibet Electric Power has always regarded consolidating the achievements of poverty alleviation and helping rural revitalization as a major political task. Focusing on the power grid construction and rural electrification in agricultural and pastoral areas, we will help the development of agricultural and pastoral areas and increase the income of farmers and herdsmen through multiple channels, improve the long-term mechanisms of employment poverty alleviation, photovoltaic poverty alleviation, consumption poverty alleviation and assistance in villages, charge and empower rural development, promote the integration of urban and rural power supply services, and be a "pioneer" of electricity with practical actions.
In 20021year, State Grid Tibet Electric Power completed 29 rural power grid construction tasks, and solved and improved the power supply problem of 73,000 people in 70 townships in 18 counties and more than 4,000 households in1year. The reliability rate of power supply in rural areas in Tibet reached 99.42%, which provided strong power support for rural revitalization.
Silver lines fly over the roof of the world, and lights light up the plateau night sky.
Reliable electric energy injects inexhaustible power into the high-quality development of the snowy plateau, and innovative electric energy makes the plateau people live a rich and healthy life.
