Recently, Dongfang Electric Machinery Co., Ltd. successfully passed the in-plant type test for the first 400 MW steam turbine generator produced by the Eastern Power Plant in Shenzhen with the F-class gas turbine, which filled the large-capacity all-hydrogen external cooling heavy-duty gas turbine in China. The blank of the machine.
In January 2003, Japan’s Mitsubishi Heavy Industries Group and Dongfang Electric Group formed a consortium to win the supply contract for 10 F-class gas turbine power generation equipment in the first international bidding project for 23 heavy-duty gas turbine combined cycle power plants in China; In the month, Dongfang Electric and Dongfang Electric signed a subcontract for gas turbine generators and their auxiliary systems. In July 2003, Dongfang Motor signed a 100% transfer of the world's leading gas turbine generator manufacturing technology with Mitsubishi Electric Corporation of Japan. Technical service contract. Through the introduction, digestion and absorption of this technology, Dongfang Motor hopes to get out of a Chinese road that independently bids, independently designs and independently manufactures large-capacity heavy-duty gas turbine generators.
Due to historical reasons, before the introduction of heavy-duty gas turbine power generation equipment technology, the production of China's gas turbines is still at a very backward level. The largest gas turbines and their associated generators that can be produced in China are only only 20,000 to 50,000 kilowatts. In order to achieve a qualitative leap, the Chinese government decided to use the market for technology, through the introduction of tenders, the introduction of heavy-duty gas turbine design and manufacturing technology from abroad, Dongfang Motor became the first challenger.
In the world, generator technology is basically divided into two types: Westinghouse School and GE Genre. The technology of Dongfang Motor is similar to GE Genre, while the 400MW generator of Mitsubishi Corporation of Japan belongs to Westinghouse School. Dongfang Motor is designing and manufacturing. There is a lack of matching experience in all aspects of testing and testing. Together with the 400 MW gas turbine generator, it is one of the world's largest single-capacity all-hydrogen externally cooled turbine generators. It has high technical content and technical difficulty. In order to fully grasp the technical requirements of heavy-duty gas turbine generators, Dongdian people carried out difficult introduction work, and more than two years of efforts finally filled the gap of China's large-capacity all-hydrogen external cooling heavy-duty gas turbine generators. In the process of manufacturing this gas turbine generator, Dongfang Motor basically mastered the technology and manufacturing process of this type of machine, and became the only manufacturer in China that can independently bid and independently manufacture hydrogen externally cooled heavy-duty gas turbine generators.
