In 2009, the 1000 kV UHV AC pilot demonstration project in southeastern Shanxi and Jingmen became the focus of attention in Shanxi Province from the moment it was put into operation.
This is a strategic choice for the State Grid Corporation of China to optimize resource allocation. Taking this as a starting point, the State Grid Corporation of China has entered a new era of advancing the “transformation of power grid development methodsâ€.
This is the "high-speed channel" for the transmission of electricity from Shanxi's new energy base. As a symbol, Shanxi's economy will move toward a healthy development.
To scramble for time, "coal power and power" has always been an unwavering choice for Shanxi province, an energy province.
The "10th Five-Year Plan" period is the best time for development in Shanxi. In the past five years, the Shanxi Provincial Party Committee and the Provincial Government have conscientiously implemented a series of decision-making arrangements by the Party Central Committee and the State Council, closely focused on the strategic objectives of building new energy and industrial bases, intensified economic restructuring, and worked hard to build a harmonious society. The province’s economic and social development The pace has been significantly accelerated. The province's GDP has grown at an average annual rate of 13.1%, which is 5 percentage points higher than the planned target. The total economic output rose from 21st in the country to the 16th in 2000; per capita GDP rose from 20th in the country in 2000 to 15th.
With the sustained and rapid economic development, Shanxi has become one of the most power-starved provinces in the country. In order to reduce the power gap, from 2003 to 2004, the Shanxi Provincial Electric Power Company invested a total of 9.8 billion yuan in the construction of main grids, equipment reconstruction and technological upgrading. The total investment amount is equivalent to the sum of the past 10 years. Today, Shanxi Power Grid has achieved a leap from the regional power grid of 35 kV and 110 kV to the unified power grid of 220 kV and 500 kV, and it has achieved the cooperation with the provinces of Beijing, Tianjin, Hebei, Shaanxi, and Mongolia ( Autonomous regions and municipalities) networking. The strategic measures of coal-fired power generation in Shanxi, such as “Jindian Xia Jiang Nanâ€, have always played an irreplaceable role in the country’s energy allocation.
On June 27, 2006, the State Grid Corporation of China and the Shanxi Provincial Government signed a summary of the talks and reached consensus on accelerating the development of Shanxi Power Grid. Both parties agreed that the next five years will be a period of rapid development of Shanxi's power grid construction, and an important period for the construction of power grids and new energy and industrial bases. It is imperative to accelerate the pace of power grid construction.
Located in the southeast of Shanxi Province, Changzhi City is the starting point for UHV AC pilot demonstration projects. At present, the total installed capacity of power in Changzhi is 2.0449 million kilowatts. In addition to the total installed capacity of 3.6 million kilowatts of Yushan Power Plant and Wangqu Power Plant, Hexin Power Plant, and Daishan Power Plant Phase II that have already been put into operation, plans are underway to start construction. Zhaozhuang Power Plant, Gaohe Power Plant, Yonghexin Power Plant, Wangqu Phase II Expansion Project, Changzhi Thermal Power Plant, etc., have a total installed capacity of 5.4 million kilowatts. It is estimated that by the end of the “Eleventh Five-Year Plan†period, the total installed capacity in Changzhi will reach 12.15 million kilowatts.
According to the "Eleventh Five-Year Plan" and the 2020 Long-Term Goals Report of Shanxi Power Grid, the total installed capacity of large power plants will reach 14.54 million kW at the end of the "Eleventh Five-Year Plan" period, including external power transmission capacity. Up to 6.9 million kilowatts.
Just like highways where coal transportation needs to be smooth, power transmission must also have large-capacity, high-power, long-distance, and high-efficiency grid channels. Shanxi needs to take the initiative in the “Rise of Central Chinaâ€, take the development path of “big coal power, large market, and large deployment†and implement the strategy of optimizing resource allocation based on the priority of coal-fired power and transmission. The construction of UHV power grid is undoubtedly The best way out.
In 2005, when General Secretary Hu Jintao visited Shanxi Province, he pointed out: "As a major coal province, Shanxi has a comparative advantage in terms of resources. It must not only contribute to meeting the country's energy needs, but also strive to build new energy and industrial bases." It pointed out the direction for energy development in Shanxi.
Statistics show that in 2005, Shanxi Province produced 550 million tons of coal, of which 400 million tons were externally transferred. The contradiction between transportation and transportation is very prominent, and coal for power generation only accounts for 25% of coal used in the province. At present, the coal gangue has reached 1 billion tons of stockpiles, and 80 million tons are newly added every year. This has caused tremendous environmental pressure. If it is not comprehensively utilized, it will cause serious waste of resources.
Shanxi is located inland, deep in the mountain, with inconvenient traffic. With the continuous expansion of the distance and scope of energy sources and places of consumption, transportation of raw coal by railways and roads alone will be increasingly restricted by the “bottleneck†of transport capacity, and it will also cause secondary pollution along the way. However, through the power grid, especially the transmission of ultra-high voltage power grid, Shanxi has a great advantage. Shanxi is located in the center, about 500 kilometers away from Beijing-Tianjin-Hebei, about 900 kilometers from Central China, and about 1,500 kilometers from East China, all within the economical and reasonable power transmission range of UHV power grid.
Located in the southwest of Changzhi City, Changzi County, where the UHV AC pilot project is located, has a county area of ​​1,060 square kilometers, abundant coal and water resources, and convenient transportation. The planned 1000 kV Jindongnan Substation is located in Cuijiazhuang, about 22 kilometers away from the urban area. It is about 400 meters away from the secondary road in the county of Linzi County to the south, and 500 kilometers of the Yulin II return line is about 1 km to the east. The area of ​​the site is farmland, and the terrain is open and flat. It is not within the planned mining scope of the coal mine and there are no relics underground. The terrain of the site is gentle, and rainwater drainage conditions are very good, and it is close to the road, which is conducive to equipment transportation. The site of the site is collapsible loess, generally 2 to 4 meters thick, and Class I non-self-weight collapsible loess. The water depth of the site is 7.1 meters to 10.1 meters. The minimum temperature of the site is minus 30 degrees Celsius, the annual average temperature is 5 degrees Celsius, the maximum wind speed is 30 meters per second, and the maximum ice coverage is 10 millimeters. These conditions are very favorable for the early construction and later operation of the UHV project. The site is 17 kilometers from Zhaozhuang Power Plant and 45 kilometers from Jincheng Power Plant.
It is 12 km from Gaohe Power Plant. The site can use an area of ​​49 hectares, according to the PTMOA closed plan layout, the first phase of the project substation covers an area of ​​7.3867 hectares.
Extremely talented people and if they say that “the time of day†and “geographical advantage†provide good objective external conditions for UHV to start in Shanxi, then “people and harmony†creates a more favorable environment for UHV pilot demonstration projects to start as early as possible.
During the National "Two Conferences" in 2006, a proposal to "start construction of the UHV power grid demonstration project as soon as possible" was passed in the Shanxi delegation. The 47 National People's Congress representatives solemnly signed their own names.
UHV, condensing the expectations and dreams of 30 million Shanxi people, contains the infinite ambition and yearning of the people of Sanjin. The State Grid Corporation of China and the Shanxi Provincial Government signed a summary of the talks and further promoted the construction of UHV power grid projects. The construction of ultra-high voltage power grids has become the Shanxi-Xinjin-rich-mined project that transforms coal into transmission energy for Shanxi.
In order to build an UHV power grid in Shanxi Province, the main leaders of Shanxi Provincial Party Committee and Provincial Government have held special conferences and researches, established a project coordination and leadership agency, issued the “Notice on Accelerating the Construction of Power Gridsâ€, and appealed to the relevant state agencies through various channels. Start early. The provincial government also submitted a report to the State Council on the "Request to Settle a National One-million-Volt High-Voltage Transmission Line Demonstration Project in Shanxi." The Fourth Plenary Session of the Eighth CPC National Committee and the Fourth Session of the Tenth Provincial People’s Congress and CPPCC National Committee specially included the UHV project as an important issue.
The Changzhi Municipal Party Committee and the Municipal Government gave great importance to and supported the UHV project, and established the Changzhi City UHV Project Coordination and Coordination Leadership Group and the Coordination and Cooperation Professional Group. The Changzhi Municipal Party Committee and the Municipal Government had held four special sessions on UHV in five consecutive days. They handled seven countersigned documents within two days. With the shortest time and fastest speed, they successively formed over 60 substation land and line corridors. The "commitment to construction" commitment document and review comments provided a green light for the U.S. pre-primary work.
The party group of North China Power Grid Co., Ltd. has held a special meeting since the start of the UHV preparatory scientific research work, requiring all levels of staff to raise awareness and serve the overall situation, starting from the establishment of a good image of the “State Grid†and accelerating the “two transitions,†uniting and cooperation. With close cooperation, high-efficiency and high-quality services for UHV construction.
Shanxi Provincial Electric Power Company proposed to build a "golden brand" for the construction of UHV projects to support Shanxi's energy strategy. The units, departments and personnel involved in the project must unswervingly implement the decision of the State Grid Corporation of the Party Group in order to "strive to surmount In the spirit of "pursuit of excellence," and spared no effort to do a good job of coordination and cooperation, fully cooperate with the UHV scientific research, construction, and construction, and always regard "service UHV, UHV support, UHV research" as the primary political responsibility, Economic responsibility and social responsibility.
Nowadays, the UHV AC pilot demonstration project has been implemented on schedule. The UHV project has enabled China's power grid to leapfrog development from here, and it has also enabled Shanxi, known as a major province of energy, to start dancing.
This is a strategic choice for the State Grid Corporation of China to optimize resource allocation. Taking this as a starting point, the State Grid Corporation of China has entered a new era of advancing the “transformation of power grid development methodsâ€.
