On December 9, the China Federation of industrial economics released the announcement of the Fifth China Industrial awards, and the "localization and development of 650MW nuclear power steam turbines" of Harbin Electric Power Group Harbin Turbine Works Co., Ltd. (hereinafter referred to as "Harbin electric turbine") won the honor of "recognition and award of China Industrial awards", which is also the following December 2016, On December 9, the China Federation of industrial economics released the announcement of the Fifth China Industrial award. Harbin Turbine Works Co., Ltd. (hereinafter referred to as "Harbin Turbine") won the honor of "Recognition Award of China Industrial Award" for the "localization and development of 650MW nuclear power turbine", which is also the second award of "China Industrial Award" in December 2016, After the "Zhundong coal fired ultra supercritical boiler development and engineering application demonstration project" of Harbin electric boiler won the China industry award, Harbin Electric Group won the China industry award again

the China industry award is the highest award in China's industrial field approved by the State Council in 2004. It is known as the "Oscar" of China's industry, which aims to commend adhering to the scientific concept of development and walking 2 The switch movable shaft is rusted or stuck on the new industrialization road with Chinese characteristics, which represents the direction, road and spirit of China's industrialization, the highest level of industrial development, and industrial enterprises and projects that have made significant contributions to enhancing comprehensive national strength and promoting national economic development, so as to establish a number of excellent benchmark enterprises and projects, and drive the formation of a large number of enterprises with core competitiveness. The awards include "China Industry Award", "China industry award Recognition Award" and "China Industry Award nomination Award", which are jointly organized and implemented by the China Federation of industrial economics and 12 national industry associations, and are selected and commended every three years. In June 2017, Harbin electric power turbine "localization development of 650MW nuclear power turbine" was recommended by Heilongjiang Provincial Enterprise Federation and applied for the Fifth China Industrial award. "Localization research and development of 650MW nuclear power steam turbine" won the "Oscar" of Chinese industry, which fully reflects the design and manufacturing level of Harbin electric steam turbine in the field of nuclear power steam turbine, and further consolidated the leading position of Harbin electric steam turbine in the domestic nuclear power conventional island material testing machine club

this project is mainly the technology that has been successfully applied in the development of Qinshan No.3 and No.4 650MW nuclear power domestic steam turbines. It is the first time in China to realize the design, test and manufacture of the last and secondary last stage blades of 650MW full speed nuclear power steam turbines, forming a systematic specification for the design and manufacture of long blades (including erosion prevention and dehumidification technology); The oil supply system technology of main oil pump turbocharger pump is optimized, which has the advantages of low power consumption, low noise and stable system; According to the single component formula, the nuclear safety requirements of traditional operation processes such as mixing, spraying and evaporation can be omitted. The probability analysis method is used for the first time in China to analyze the probability of steam turbine rotor flying crack; It is the first time to realize the independent design and manufacture of nuclear power main steam control valve; Adopt new condenser modular design technology to shorten the on-site installation cycle; It has established a nuclear power turbine electro-hydraulic joint commissioning test bench, achieved the characteristics of electro-hydraulic joint commissioning test in the factory for the first time, and made breakthroughs in the world's advanced and domestic leading nuclear power technology

Qinshan 3 and 4 650MW nuclear power domestic steam turbines have independent intellectual property rights. The successful operation of the project has formed a distinctive nuclear power turbine design system, promoted the development of industrial design technology, and achieved significant economic and social benefits, marking the full localization of design and manufacturing of 650MW nuclear power units in China. The overall technology of the project has reached the international advanced level and won the "second prize of China Nuclear Energy Association" after being identified by industry experts organized by China Nuclear Energy Association. At the same time, the two 650MW nuclear power steam turbine units provided by Harbin electric turbine for Hainan Changjiang have been combined for power generation. At the 2016 work summary and commendation conference of China Southern Power, Hainan Changjiang nuclear power plant unit 1 stood out in the evaluation of more than 300 steam turbine generator units in five southern provinces with excellent operation performance, won the "2016 system operation efficiency Award" and won the crown of "gold medal unit"

Recently, four of the world's first AP1000 nuclear power steam turbine units designed and manufactured by Harbin electric power turbine have been successively combined for power generation, and all of them are ready for commercial operation, which makes China the first country in the world to successfully apply the third generation nuclear power AP1000 technology, and Harbin electric turbine has also become the first country in the world to participate in the design and manufacture of AP1000 third generation nuclear power conventional island main equipment, And the only important equipment manufacturing enterprise with unit operation performance. On the basis of the successful localization of the AP1000 third generation nuclear power demonstration project, Harbin electric power turbine adheres to independent innovation, and has carried out the complete independent design and manufacturing of megawatt nuclear power units, and successfully completed the research and development of many reactor type nuclear power turbine units such as Hualong 1, vver-1000, cap1400, CANDU heavy water reactor, offshore nuclear power platform, multipurpose small reactor, low temperature heating reactor, etc. The 1800mm half speed long blade with fully independent intellectual property rights, which is derived and developed from the AP1000 technical system, is the only half speed nuclear power long blade in China that has passed the model machine verification test, has fully independent intellectual property rights, and has completed the test, and will be applied to the Hualong 1 and AP1000 optimization designed and manufactured by Harbin electric turbine. In May this year, the fully autonomous design and manufacture of vver1000 nuclear power turbine - unit 3 of Tianwan phase II project has been successfully put into operation, and unit 4 is under installation and commissioning
