The hottest zharut Qingzhou UHV DC entered live co

  • Detail

Recently, the live commissioning of the "zarut Qingzhou" ± 800 kV HVDC transmission project can be started after the completion of the live commissioning for one month. This transmission line starts from Tongliao City in Inner Mongolia and ends at Qingzhou converter station in Weifang, with a total length of 1234 kilometers. It can transmit 55billion kwh of electricity to Shandong every year, which is equivalent to saving 25.2 million tons of standard coal

the zhalut Qingzhou UHVDC project was approved by the state on August 16, the converter station was fully started in August, the zhalut Qingzhou ± 800 kV HVDC project was officially started on August 25, and the line was fully started in September, with a power transmission capacity of 10million kW

zhalut Qingzhou ± 800 kV HVDC project starts from zhalut converter station in Tongliao City, Inner Mongolia Autonomous Region and ends at Qingzhou converter station in Weifang City, Shandong Province, passing through Inner Mongolia, Hebei, Tianjin and Shandong provinces (cities and districts). The line length is 1234 kilometers. Two new converter stations are built in zhalut and Qingzhou, with a rated transmission capacity of 10million kW and a total investment of 22.1 billion yuan

it is understood that the zarut Qingzhou UHVDC project is of great significance

first, it will effectively alleviate the power shortage in Shandong and ensure the safe and reliable supply of power. Shandong is a major economic province in China, with a large population and a good industrial foundation. Heavy industry is the main feature of the economic structure, and the demand for electricity continues to grow steadily. Due to the lack of primary energy resources and the limited land and environmental protection space, it is extremely urgent to accept the power outside the region on a large scale. Especially since late July this year, Shandong's power load has reached a record high of 69.959 million KW. The first UHV project in Shandong, Ximeng Shandong UHV AC project, which has just been put into operation, has delivered 2million kW of external power in time, making up for the power gap at the critical moment and playing an important role in meeting the peak and summer power supply. Considering the power supply projects under construction and approved, as well as the power supply of Ximeng Jinan, Yuheng Weifang UHV AC and Shanghai Miao Linyi UHV DC channels, it is estimated that the new power market space in Shandong will reach 9.3 million KW and 13.3 million kW in 2018 and 2020 respectively. After the completion of zhalut Qingzhou UHVDC project, the transmission capacity will reach 10million kW, which will effectively alleviate the tension between power supply and demand in Shandong and support the needs of economic and social development in Shandong

the second is to implement the action plan for the prevention and control of air pollution and improve the ecological environment. In recent years, the haze problem in the eastern and central regions of China is serious, and the CPC Central Committee and the State Council attach great importance to it. 23. Personnel training in September 2013, the state issued an action plan for the prevention and control of air pollution. In March, 2014, the national development and Reform Commission, together with the national energy administration and the Ministry of environmental protection, issued the notice on printing and distributing the work plan for strengthening the prevention and control of air pollution in the energy industry (fgy [2014] No. 506), requiring that the proportion of Beijing Tianjin Hebei, the Yangtze River Delta, the Pearl River Delta and Shandong Province receiving external power transmission be gradually increased, so as to realize the negative growth of total coal consumption and alleviate the pressure of air pollution prevention and control in densely populated areas. The construction of UHV DC converter station in zhalut, Inner Mongolia, gathers the surplus thermal power and wind power of Inner Mongolia, Jilin, Heilongjiang and Liaoning provinces (regions), and transmits electricity to Shandong through UHV DC. The annual transmission of electricity is about 55billion kwh, which can reduce the transportation of coal by 25.2 million tons, reduce the emission of carbon dioxide by 49.5 million tons, such as plastic oil pan, valve cover, battery tray, engine mounting bracket, fuel rail Throttle valve body, intercooler system end cover and pipeline, etc; 124000 tons of sulfur and 131000 tons of nitrogen oxides will effectively promote the realization of the goal of air pollution prevention and control in the mechanical property experiments of metal, non-metal, composite materials and products

third, alleviate the problem of "electricity shortage" in Northeast China and promote economic and social development. In recent years, the growth of power demand in Northeast China has slowed down, and the installed capacity has continued to increase, resulting in serious power generation problems. The opinions of the State Council on several major policies and measures to support the revitalization of Northeast China in the near future (GF [2014] No. 28) clearly requires that the construction of power transmission channels be accelerated to effectively solve the "power shortage" problem in Northeast China. During the 13th Five Year Plan period, the surplus power in Northeast China was about 20million kW. The construction of zhalut Qingzhou UHV project, with an additional 10million kW transmission capacity, can absorb more than half of the surplus power, effectively alleviate the pressure of "power generation", improve the utilization and economy of the installed capacity of the existing power supply, and promote the economic and social development of the northeast region

fourth, promote the consumption of wind power in Northeast China, but how about the degree of fragmentation and the wider consumption of clean energy. Northeast China is located in the prevailing westerly belt in the mid latitude of the northern hemisphere, and is very rich in wind energy resources. According to the notice of the general office of the State Council on printing and distributing the strategic action plan for energy development (year) (GBF [2014] No. 31), the state will focus on planning and building nine large-scale modern wind power bases, including Eastern Inner Mongolia, Jilin and Heilongjiang. By the end of 2015, the installed capacity of wind power in Northeast China was 24.67 million KW, accounting for 20% of the total installed capacity, which is the regional power with the highest proportion of wind power installed in China. The construction of zarut Qingzhou UHV project is conducive to realizing the optimal allocation of clean energy resources such as wind power in a wider range, promoting the consumption of wind power in Northeast China, reducing the proportion of coal consumption in receiving areas, and optimizing the energy structure
