The hottest State Grid 30 measures to help stabili

  • Detail

On February 28, the mobilization meeting for the commencement of the 00 kV High Voltage DC project (hereinafter referred to as "North Shaanxi Hubei project") in China's plastic machinery market was held in Beijing. Maoweiming, chairman and Secretary of the leading Party group of China National Household Appliances Co., Ltd., announced the commencement of the project

the state power company has resolutely implemented the decisions and arrangements of the Party Central Committee and the State Council, successively issued 10 measures to support epidemic prevention and control and power supply service guarantee, issued 12 measures to deal with the impact of the epidemic, fully resume construction, and promote the resumption of work and production of enterprises, and issued 8 measures to implement the policy of periodically reducing electricity costs. The package plan formed by these three measures shows the "great power and important tool" and "pillar" role of State Grid

by the end of February, the company had started key projects such as Shanxi Yuanqu pumped storage power station, and resumed work on more than 1600 power transmission and transformation, hydropower and new energy projects such as Qinghai Henan UHV DC project, alilian project, Hebei xiong'an new area supporting facilities, and Winter Olympics supporting facilities. The total scale of the commencement and resumption projects exceeded 100 billion yuan, which has driven the power equipment manufacturing enterprises to resume work and production. At present, the resumption rate of five equipment manufacturing units of the company has reached 93%, more than 20 major equipment manufacturing enterprises and key laboratories of UHV and pumped storage projects have resumed production, and more than 100 line material enterprises and hundreds of supporting equipment enterprises have resumed production

the Northern Shaanxi Hubei project is a key project to promote the western development and the rise of the central region, and it is a key project of the national "13th five year plan". The North Shaanxi Hubei project starts from Yulin, Shaanxi Province and ends in Wuhan, Hubei Province, passing through Shaanxi, Shanxi, Henan and Hubei provinces, with a total length of 1137 kilometers. The sending end connects Northern Shaanxi energy base and Northwest 750 kV AC, and the receiving end connects Hubei load center and central China 500 kV AC. The project has a rated voltage of ± 800 kV, a rated transmission capacity of 8 million KW, and a total investment of 18.5 billion yuan. It is planned to be completed and put into operation in 2021. Relying on the North Shaanxi Hubei project, the company will promote the standardization of "double 800" UHV DC technology, equipment and design with ± 800 kV and transmission capacity of 8million kW, promote the independent research and development, production and application of DC bushings, drive the innovation and development of the whole UHV DC industry chain, and create a model project for UHV technology upgrading

according to the State Grid Corporation of China, Hubei and Wuhan are the top priority of epidemic prevention and control, and the decisive place to win the fight against epidemic prevention and control. The construction of the Northern Shaanxi Hubei project, the creation of a major energy transmission channel for power transmission in Shaanxi and Hubei, and the role of power infrastructure as a "ballast" and "booster" for stable economic growth are of far-reaching significance for winning the Hubei defense war and the Wuhan defense war, boosting Hubei's confidence in economic and social development, and "reinvigorating" China's economy

first, it is conducive to stabilizing investment and employment, driving upstream and downstream enterprises to resume production and economic growth. UHV has large investment and significant medium and long-term economic benefits. It has the advantages of long industrial chain and strong driving force, which can effectively drive the power supply, electrical equipment and energy consumption. In addition, it can also enhance cell adhesion and proliferation equipment, raw materials and other upstream and downstream industries. The Northern Shaanxi Hubei project connects Hubei and Northern Shaanxi, directly drives the equipment production scale of about 12billion yuan, increases more than 40000 jobs, drives the investment in power supply and other related industries of more than 70billion yuan, and boosts the transformation and upgrading of power transmission and transformation equipment manufacturing industry. After the completion of the project, it will play an important role in reducing the energy cost of the whole society in Hubei, promoting the transformation of the resource advantages of Northern Shaanxi into economic advantages, helping to eradicate poverty and promote regional coordinated development

secondly, ensure the safe and reliable supply of electric power in Hubei. Hubei Province is an important province to implement the rise strategy of the central region, with a large demand for electricity. Due to the lack of primary energy resources, limited land and environmental protection space, there is a great pressure to ensure power supply. The UHV project will be used to directly transmit the power of Northern Shaanxi energy base to Hubei load center, with an annual power transmission of 40billion kwh, equivalent to replacing 18million tons of raw coal at the receiving end and reducing 29.6 million tons of carbon dioxide. It can effectively alleviate the medium and long-term contradiction between power supply and demand in Hubei and central China, and help win the battle of pollution prevention and control. The cooperation between the Northern Shaanxi Hubei project and the existing UHV project in Central China can give full play to the advantages of UHV power in large capacity, long distance and low loss, effectively support the construction of UHV AC and DC main frame in Central China, and optimize the local power supply structure

in addition, promote the development and delivery of energy bases. Shaanxi is rich in energy resources. It is a major energy province in China. At present, the proven energy holdings are among the top in the country. The coal resources in Northern Shaanxi are widely distributed, with large reserves, good coal quality and easy exploitation. The construction cost of power supply and power generation cost are relatively low. Shaanxi is rich in new energy resources such as wind energy and solar energy, with great development potential and obvious complementary advantages of multi energy. In 2020, the installed capacity of new energy will be close to 20million kW, which will be mainly concentrated in Northern Shaanxi. It is expected that the demand for power transmission in Northern Shaanxi will exceed 10million kW during the 14th Five Year Plan period. After the completion of the Northern Shaanxi Hubei project, it will effectively promote the intensive development of Northern Shaanxi energy base and large-scale power transmission, promote the efficient utilization of energy resources, and effectively guide the rational layout of related industries

State Grid Corporation of China said that it would coordinate the epidemic prevention and control and the company's business reform and development, resolutely win the people's war, the overall war and the interdiction war of epidemic prevention and control, promote the revolution of energy production and consumption, build a clean, low-carbon, safe and efficient energy system, and use practical actions to serve the "six stabilities" work, so as to make new and greater contributions to the decisive victory in building a moderately prosperous society in all respects and the decisive battle against poverty
