Harbin Electric Machinery Factory 840 MW hydropower unit ranks internationally leading
Recently, in Yichang, Hubei Province, the Science and Technology Department of Heilongjiang Province has identified the Harbin Electric Machinery Co., Ltd. (hereinafter referred to as Ha Electric) on behalf of China's “Major Air-to-Air Cold Water Turbine Generator Key Technology and Equipment Development†project.
Liang Weiyan, academician of the Chinese Academy of Engineering, director of the appraisal committee, Lei Qingquan and Tang Renyuan, academician of the Chinese Academy of Engineering, Huang Ling, director of the equipment department of the State Council's three construction committees, Zhang Changbin, deputy director of the Heilongjiang Provincial Science and Technology Department, and Jiang Zhisheng, deputy director of the Heilongjiang Provincial Machinery Federation, Yangtze River, China Liu Liren and Cheng Yongquan, deputy chief engineers of the Three Gorges Project Development Corporation, Zhang Cheng, general manager of China Yangtze Power Co., Ltd. and members of the expert group determined that the project has reached the international leading level.
According to Fu Jianping, deputy director of the Three Gorges Power Plant of China Yangtze Power Co., Ltd., after the operation of the No. 26 and No. 25 full-air cold water turbine generator sets provided by Harbin Electric Power Co., Ltd., the operating conditions are normal and the indicators meet the contract requirements. The model test data, real machine data and design calculation data of the ventilation system are basically consistent.
Experts have also made valuable suggestions and expectations while affirming the outstanding achievements of the “Giant Full-Air Cold Water Turbine Generator Key Technology and Equipment Development†project undertaken by Harbin Electric.
Fu Yuanchu, former deputy general manager of China National Water Resources and Hydropower Construction Corporation, believes that Harbin Electric has created a new era of all-air-cooled giant generator technology, achieving the expected goals in the technology of electromagnetic, ventilation and insulation of generators, reaching the world's leading level. . This is a major breakthrough for China's hydroelectric generating units.
The expert's appraisal conclusion is: The Three Gorges Hydropower Station has a total of 32 hydroelectric generating units with a capacity of 700 MW (maximum capacity of 840 MW). It is the largest hydropower station with the largest single unit capacity and total installed capacity in the world, 23~ A total of six units on the 26th, 31st and 32nd are all-air-cooled water turbine generator sets, which are independently designed and manufactured by Harbin Electric Power. Since the official commissioning of Units 26 and 25, the technical performance has reached the relevant standards and design requirements. The turbine stability index and the temperature rise index of the generator are superior to the standards and the provisions in the contract.
The successful development of the 840 MW all-air cold water turbine generator set has improved the overall development of the unit's hydraulic development, electromagnetic design, ventilation design, insulation technology, structural design and manufacturing process, greatly improving the power generation of the giant hydroelectric generator. The ability of the unit to independently develop, design and manufacture.
The subject has the following innovations: First, the hydraulic turbine has made breakthroughs in hydraulic design. The problem of the pressure pulsation zone in the high partial load zone of the Three Gorges left bank unit has been solved in the Three Gorges right bank Harbin Electric Group.
Second, the complete air-cooling technology of the generator has made a major breakthrough in the application of large-capacity hydro-generators, and successfully developed the world's largest 840 MW all-air-cooled water turbine generator.
The third is the use of advanced wire corner field strength treatment technology and anti-halation technology, wire rod insulation dielectric properties, electrical aging performance and anti-halation performance.
In view of the fact that Harbin Electric has already had the design and development capability of the 840 MW unit and has had a great impact on the international situation, the expert group recommended that Harbin Electric will carry out the technical research of the 1000 MW class air-cooled water turbine generator set.
