What is the hottest Shanxi electric power Expressw

What is the appearance of Shanxi electric power Expressway?

UHV power is known as "electric highway". Shanxi's UHV project occupies an important position in the "west to East power transmission and north to South power supply", and shoulders the glorious mission of packaging and delivering Shanxi's coal, wind and photovoltaic power -

in less than 10 years, China's UHV transmission has reached the world's highest level in terms of scale and technical level, Become the "first" of global energy interconnection

according to the plan, from 2014 to 2017, Shanxi UHV project was put into operation, with a total of 9 projects of "four AC and five DC"

as of the middle of August this year, the newly-built UHV AC 1000 kV Hongshan substation, 1000 kV Beiyue substation and UHV DC ± 800 kV Yanmenguan converter station have all been completed and put into operation, becoming a new landmark of Shanxi power transmission after the UHV 1000 kV Changzhi substation was put into operation in 2009. In addition, the addition of clean energy such as wind power and photovoltaic power generation has improved the cleanliness of "Shanxi power transmission" and widened the road of energy industry transformation in our province. Shanxi "power highway" broke through the air -

local conversion of thermal power

driving on the power highway

on September 26, the fields in northern Shanxi were foggy. Under a tall transmission tower in Dai County, experts from the provincial power company were supervising the environmental protection and water conservation rectification of ± 800 kV high-voltage Yan Huai DC transmission project

at 3:36 on June 30, the double pole of ± 800 kV high voltage Yanhuai DC transmission project was officially put into operation, with a transmission power of 800000 kW on that day. The ± 800 kV high-voltage Yanhuai DC transmission project is one of the "four AC and four DC" projects of the national air pollution prevention action plan, and it is also an important project of "west to East power transmission and north to South power supply"

as China's coal power bases are mainly distributed in Shaanxi, Mengxi, Shanxi and Xinjiang, hydropower is mainly distributed in Sichuan, Yunnan, Tibet and other places, wind power and solar energy are mainly distributed in the northwest, far away from the plastic granulator, and the environmental pollution is also quite serious in the eastern load center, it is necessary to build strong electricity, implement long-distance and large-scale transmission, and optimize the allocation of energy resources nationwide. UHV transmission has the characteristics of long distance, large capacity and low loss, which can just meet this demand

nine UHV projects have been put into operation in Shanxi in recent three years. The Mengxi Jinbei Tianjin South exchange project involves 2 cities and 6 counties, of which the UHV 1000 kV Beiyue substation is located in Ying County, Shuozhou City, and the length of the line in Shanxi Province is 2 × 268.7 kilometers, 884 iron towers. The project was commenced in December 2014 and put into operation in October 2016

when we buy the tensile testing machine, we often don't know what parameters the tensile testing machine needs. Yuheng Jinzhong has a serious impact on the price, after-sales and quality of the testing machine - Weifang exchange project involves 2 cities and 12 counties, of which the UHV 1000 kV Hongshan substation is located in Pingyao, Jinzhong, and the line length in Shanxi is 2 × 316.9 kilometers, 1028 iron towers. The project was commenced in May 2015 and put into operation in March 2017

North Shanxi Jiangsu ± 800 kV HVDC transmission project involves 4 cities and 9 counties, of which the UHV ± 800 kV DC Yanmenguan converter station is located at the junction of Pinglu district and Shanyin County, Shuozhou City, and the connection address is located in Shenchi County, Xinzhou City. The line length in Shanxi is 307.9 kilometers, and the iron tower is 557 bases. The project was commenced in July 2015 and put into operation in December 2017

the completion and operation of the UHV project in our province is of great significance to promote the development and export of energy in Shanxi, expand the scope of new energy consumption, meet the power demand in East China, speed up the adjustment of energy structure, increase the supply of clean energy, and alleviate the pressure of environmental protection. The thermal power of Jinzhong and Jinbei coal power bases has been transformed locally, and the economic and long-term social benefits cannot be underestimated

the substation connects things

Jindian has a strong momentum going south

Yang Ning, project manager of Shanxi Jintong supervision company, still remembers that the summer of 2015 was unbearable, and everyone in the supervision project department who worked in high temperature for days left sunburn and peeling marks. At that time, the Hongshan 1000 kV substation located in Pingyao County, Jinzhong City was still in the stage of foundation treatment. Because the UHV Transformer was too large as a whole and the long-distance transportation was very inconvenient, the company decided to adopt the method of disassembly transportation and on-site assembly for the first time, which was the first in the world. It is estimated that if the disassembled transformer is not used, the transportation cost alone will cost more than 30 million yuan

at that time, the biggest problem was to change the spare parts warehouse in the station into the main transformer installation workshop. Because the whole transformer had to be tested and disassembled before delivery, and it had to be assembled and tested again after being transported to Pingyao, which was twice the original work volume. China's Shanxi electric power company rose to the challenge, fighting day and night for three months, and the world's first UHV Transformer split assembly workshop was completed 70 days ahead of schedule! On July 13 this year, 1000 kV high voltage Hongshan substation started live commissioning. On August 12, the power station was officially put into 168 hour trial operation

as we all know, without substations and converter stations, UHV AC systems and DC systems cannot transmit current. Power insiders use water plant pump rooms to describe their switching role. The three new substations that have been completed and put into operation in our province, we remove unqualified parts and correct them. The converter station plays an indispensable role in UHV power transmission: UHV AC 1000 kV Hongshan substation, 1000 kV Beiyue substation, UHV DC ± 800 kV Yanmenguan converter station, which respectively carries the Yuheng Jinzhong Weifang AC project, Mengxi Jinbei Tianjin South Jinbei Jiangsu ± 800 kV HVDC transmission project is an important hub

UHVDC ± 800 kV Yanmenguan converter station is located in nanhanjing village, xiangyangbao Township, Pinglu District, Shuozhou City, with a total area of 21.11 hectares. At 3:36 on June 30 this year, the ± 800 kV high-voltage Yanhuai DC transmission project bipolar was officially put into operation, with a transmission power of 800000 kW on that day

according to the analysis of power experts, the annual power transmission of Jindian "going to the south of the Yangtze River" is expected to reach 45billion kwh, equivalent to nearly 90% of the electricity consumption of the whole society in Nanjing. It can reduce 20million tons of coal transportation, 38million tons of carbon dioxide, 40000 tons of nitrogen oxide and 34000 tons of sulfur dioxide. What is more different from the last time is that a large amount of clean energy such as wind power and photovoltaic power generation in shuobei region will also be bundled and transported to Jiangsu, the economic engine of the land of plenty will be stronger, and the sea lanterns along the Qinhuai River will be lit by the wind and sunshine of the frontier fortress

help transformation and poverty alleviation

someone once summarized the characteristics of UHV: the transmission distance is "extra" far, the transmission loss is "extra" small, and the transmission capacity is "extra" strong. In fact, its transmission composition is also "extra" new. As of July, the installed capacity of Shanxi electric new energy has exceeded 10 million KW, reaching 10.73 million KW, accounting for 17% of the total installed capacity

without the UHV project in Shanxi, these clean energy cannot be transmitted over long distances. From June 23 to 26, five photovoltaic supporting projects, including Yuncheng Ruicheng photovoltaic leading technology base collection station 220 kV power transmission and transformation project, Jinneng Yanggao photovoltaic clean energy 220 kV photovoltaic transmission project, Jinneng Tianzhen shatunbao 220 kV photovoltaic transmission project, Datong Hunyuan Wucheng poverty alleviation 35 kV photovoltaic transmission project, and Shanxi energy investment Yangqu 35 kV photovoltaic transmission project, were completed and put into operation in advance, It has created a "Shanxi speed" for the construction of photovoltaic supporting transmission projects in the province

according to the data, by the end of July 2017, a total of 582 distributed and 8 centralized photovoltaic poverty alleviation power stations in the province have been combined to generate electricity, with a cumulative combined capacity of 343100 kW. These electricity are not only more "clean", but also benefit 22900 poor households to move towards a new life of poverty alleviation
