Shandong Power Grid expects that during the “12th Five-Year Plan†period, the peak load of Shandong Power Grid will increase by 11.5% annually, and the gap between power supply and demand will reach 6 million kilowatts and 12.6 million kilowatts respectively in this and next two years. The stable and rapid development of Shandong’s economy needs no further cracks. Energy constraints bottlenecks.
In order to break this bottleneck, Shandong will actively develop UHV and “transmission of foreign power†during the “12th Five-Year Plan†period, and accelerate the construction of clean energy and smart grids. This year, Shandong will further increase its efforts in power grid construction. It is estimated that 401 projects of 35 kV and above will be completed and put into operation in the year, with a length of 6,647 km and a capacity of 26,290,000 kVA, which is 2 and 1.4 times that of 2011 respectively. .
According to reports, during the “Twelfth Five-Year Plan†period, Shandong Power Grid planned and constructed “two crossings and two straights†UHV projects, in which “two crossings†refers to the 1,000 kV Ximeng-Jinan-Nanjing “Eastern Vertical†exchange project and 1000-kV Shaanxi North - Jinan - Weifang "North Transverse" exchange project; "two straight" is ± 800 kV Humeng - Qingzhou DC project, ± 800 kV Bin - Lintong East DC project. Secondly, five UHV (commutation) stations will be placed on the ground; more than 55,000 kilometers of 110 kilovolt and above lines will be used, and the substation capacity will exceed 300 million kVA; clean energy such as wind power will account for 10.7% of the total generation capacity of the entire network.
According to the plan, this year Shandong will strengthen the safety, quality, and schedule management of power grid construction as the criteria to ensure that construction of the 500 kV Linfen, Xiaolong, and Suzon power transmission and transformation projects and Haiyang nuclear power transmission line project will be started, and the Laizhou power plant transmission line project will be put into operation. . Coordinate the promotion of the construction of the 220 kV power grid project, complete the commissioning task for substations with 220 kV and above capacity of 12,420 kVA, and 2011 km of transmission lines.
In order to solve the problems of inadequate power supply capacity in individual areas and weak connection between the county area power grid and the main network, Shandong Electric Power will increase the intensity of distribution network construction and transformation this year, optimize the structure and distribution of high-voltage distribution networks, and increase the newly-added capacity of 13.875 million kVA. The new transformation line is 4636.1 kilometers. In accordance with the development plan for intelligent distribution network, the construction of the smart distribution network master station in 17 cities and 50% of the equipment in the direct supply area will be completed, and 966 new intelligent distribution network lines will be built to improve the interconnection and supply capacity and automation level.
