Energy cooperation between Chinese and German energy companies has steadily progressed around heavy gas turbines. On June 11, during the video meeting between the prime ministers of China and Germany, under the joint witness of Chinese Minister of Industry and Information Technology Miao Wei and German Minister of Economic Affairs Altmeyer, Qian Zhimin, Chairman of State Power Investment Group Co., Ltd., and Siemens AG President and Chief Executive Officer Joe Kaeser video signed “China Heavy Fuel Gas Turbine Test Power Station Project #2 Guarantee Unit Supply and Service Contract for Machine Island Equipment”. Recently, Siemens won the public bidding for the unit and will provide a set of H-class heavy-duty gas turbine island equipment and corresponding technical services for China Heavy United Gas Turbine Technology Co., Ltd. (hereinafter referred to as China Reburning), a subsidiary of SPIC.

On the same day, Qian Zhimin, chairman of the State Power Investment Corporation, signed a contract with Siemens CEO Kai Sa Video. Since last year, the two companies have entered the “honeymoon period” of heavy gas turbine cooperation.

H-class gas turbines are currently the world’s highest combustion temperature, single power and highest efficiency gas turbines, and are also the main products for Siemens, GE and other major market players competing for the Chinese gas power generation market. According to the tender announcement, the No. 2 guarantee unit machine island equipment includes gas turbines, steam turbines and generators. China’s reignited pilot power plant project will land in Shanghai, and this single supply contract becomes the fourth H-class gas turbine order that Siemens has won in Greater China after Hong Kong and Guangdong.

Since last year, State Power Investment Corporation, one of China’s largest power generation central enterprises, has been in a “honeymoon period” with Siemens. The two parties signed the “Heavy Gas Turbine Technical Cooperation Agreement” and “Strategic Partnership Framework Agreement” in March 2019, and the “Memorandum of Understanding on Green Hydrogen Energy Development and Comprehensive Utilization Cooperation” in September 2019. On this basis, the two sides continue to deepen all-round strategic cooperation in the fields of heavy gas turbines, hydrogen energy development and comprehensive utilization, and third-party market cooperation. According to the news released by the State Power Investment Corporation, after the contract comes into effect, the two parties will rely on the heavy gas turbine test power plant project to cooperate in advanced H-class heavy gas turbine engineering design, intelligent heavy gas turbine test verification base construction and other fields.

And another point deserves more attention: in heavy-duty gas turbinesThe main line behind frequent interaction and close cooperation in the field is to promote China’s independent research and development of heavy-duty gas turbines.

Ultra-large gas turbines are recognized as the most difficult mechanical equipment in the world, and they are hailed as “the jewel in the crown of the manufacturing industry”. It is no exaggeration. Taking the world’s largest gas turbine as an example, its weight is equivalent to a refilled Airbus A380, and its output is equivalent to the sum of the turbocharged engine power of 1300 Porsche 911 cars, but the accuracy error of the core components is only up to Tens of microns. It has been the dream of China’s gas turbine industry for more than sixty years to create a heavy-duty gas turbine with independent design and international level. As a latecomer to the industry, for more than a decade, China’s gas turbine autonomy has been a thorny road: subject to the lack of core technology, the development of the gas turbine industry has been ups and downs.

In 2012, China’s high-level organizations established a special demonstration committee for “two engines” (aeroengines, gas turbines) to start special demonstration work. In order to integrate and work together to overcome the difficulties of autonomy of heavy-duty gas turbines, in 2014, China Electric Power Group Heavy Duty Gas Turbine Technology Co., Ltd., a consortium formed by the former China Power Investment Corporation and Harbin Electric Group, Dongfang Electric Group, Shanghai Electric Group, Datang Group, etc. Established in Shanghai, mainly engaged in gas turbine design, R&D, test verification and assessment, gas turbine related technology development, technology transfer, technical consulting and technical services, etc. The goal is to “overcome key bottleneck technologies and form gas turbine core technologies with independent intellectual property rights.” After the reorganization of China Power Investment Corporation and the State Nuclear Power Technology Corporation, the company became the holding company of State Power Investment Corporation. In December 2016, the second meeting of the “Two Engines” special leading group was held. The meeting specified that SPIC as the main responsibility for the implementation of the “Two Engines” special heavy gas turbine project, and China Heavy Gas Turbine Technology Co., Ltd. was specifically responsible for the implementation. In 2017, SPIC and Tsinghua Holdings Co., Ltd. signed a cooperation agreement for the reorganization and reorganization of Huaqing Gas Turbine Company by China Reburning. The two reached the integration of resources in R&D team, intellectual property and other aspects.

Since then, China has once again focused on the goal of independent research and development and manufacturing of heavy-duty gas turbines. Through independent design, development, and technical cooperation, “Walking on Two Legs”, China’s heavy-duty gas turbines The process of independent innovation has significantly accelerated.

In July 2018, SPIC successively signed a memorandum of understanding on cooperation with Siemens Germany and Ansaldo Energy Company of Italy, which clarified the two parties’ technology in the field of heavy gas turbines Intention to cooperate. Eight months later, SPIC and these two major heavy-duty gas turbine suppliers formally signed a technical cooperation agreement for heavy-duty gas turbines. According to Peng Mei News, SPIC and SiemensThe Saldo Company has negotiated on different degrees of technology transfer for heavy-duty gas turbines. Both have become partners of SPIC’s independent research and development of a new generation of domestically produced gas turbines.

In 2019, SPIC successfully completed the conceptual design of 300MW class F heavy duty gas turbine, the overall design of 400MW class G/H heavy duty gas turbine and the conceptual design of three major components. Since the beginning of this year, China Reburning is fully promoting the realization of the main goals of the reburning project in 2020: 300MW class F heavy duty turbines will complete the preliminary design transition before the end of the year, and 400MW class G/H heavy duty turbines will complete the conceptual design transition before the end of the year. The compressor and high-temperature component test bench will be double-started during the year.
