Basic research and cutting-edge technologies are important bases for researching, aggregating and cultivating outstanding scientific and technological talents and for conducting academic exchanges.

First, it tackled many key hydraulic design technologies. Combining the needs of domestic and foreign power generation equipment markets and technological development trends, Haji Electric has taken the lead in developing a 1000MW Francis turbine generating unit with world advanced level, and has carried out a full-scale unit of millions of kilowatts in Wudongde and Baihetan. Air cooling simulation test, test results fully meet the requirements.

At present, the development of hydropower units with millions of kilowatts of Kazakhstan Motors has reached the international advanced level. It is gratifying that the efficiency of the Turbine Runner of the Udongde Mega Hydropower Station developed by the company reached 94.7%, the efficiency of the Turbine Runner of the Baihetan Hydropower Station reached 94.9%, and the performance indicators were of international advanced level. At the same time, the key technologies of the large-scale hydropower units with a million kilowatts of power and the design of key insulation technology tests and electromagnetic solutions have all been completed. Among them, the domestic and foreign advanced level of the 24kV/26kV hydroelectric stator bar main insulation technology of millions of units has laid a solid foundation for the adoption of air cooling for the 1000MW giant water turbine generator.

Secondly, to achieve a breakthrough of “zero” in large-scale pumped storage units in China. For many years, the turbine runners of most large-scale Francis turbine units in China have adopted foreign technologies. Although domestic enterprises have a large share of subcontract manufacturing, due to the high cost of technology transfer and the extremely low profitability of enterprises, they are actually working abroad. In order to change this situation, using the advantages of the laboratory's development, Harbin Motors has adopted advanced digital technology for system integration through technical cooperation and introduction. In a relatively short period of time, it mastered the development technology of the Francis runner and developed a suitable The high-performance runner required by the power station has realized the independent design and manufacture of large-scale Francis turbine units in China.

At the same time, Haji Motors established the digital platform for China's first research on innovative turbine runners, which integrates research and development, design, manufacture and testing of hydropower equipment. The research results have been further promoted and applied. So far, the National Laboratory has successfully developed the runners of large-scale mixed-flow power stations, such as Gongboxia, Sanxia, ​​Xiangjiaba and Xiluodu, and entered the United States, as well as Pakistan, Vietnam, Iran, and Myanmar.

Third, ventilation cooling technology has reached the international advanced level. In the development of new large-scale hydropower products, Haji Motors seized the opportunity to enter the right bank of the Three Gorges Project and devoted troops to crack down on the world's problems such as excessive temperature rise caused by poor air cooling performance, and completed electromagnetic calculation and ventilation cooling for all-air cooled motors. The overall coordination of the system, such as design and optimization, successfully completed the development of the Three Gorges air-cooled unit with independent intellectual property rights.

With the "unique skills" developed through technological innovation, Harbin Motors has taken over this type of domestic hydroelectric generator market. The Three Gorges unit has been operating for three years and has created the world record of air-cooled units with the largest single rated capacity and the longest continuous safe operating time in the world. At present, Haji Motor has formed the industrialization advantages of large-scale air-cooled units. The large-scale hydropower units such as the Longtan, Xiaowan, Laxiwa, Xiluodu, Xiangjiaba power stations that were signed have also adopted full air cooling technology.

Fourth, the research results of the large-capacity turbine generator high-efficiency energy-saving circulating pump were introduced. This action better solved the problem that circulation pumps of large-scale turbo-generators in China generally have the problems of low unit efficiency, severe cavitation erosion and poor stability, which seriously affect the stable operation of the power station.

People in the technical radiation center generally believe that the national laboratories have become the base for the transformation of hydropower equipment technological achievements and the origin of advanced technologies, and form radiation.

In order to enhance the overall level of national hydroelectric power generation equipment, Harbin Motors has been engaged in scientific research and has also communicated with many parties and shared technical resources. Through the effective organization and use of social and technological resources for corporate innovation services. During the construction of the national laboratory, its high head test bench, ventilation cooling test bench, 3000T thrust bearing test bench, etc. are all included in the open sharing platform of the equipment and equipment of the relying unit to realize resource sharing nationwide.

First, units and individuals that need to use key equipment can carry out scientific research, industrialization, and engineering scientific tests of new products through sharing platforms, and improve the utilization rate of experimental platforms. Second, through the joint research with other domestic large-scale enterprises, scientific and technological economic entities, universities and research institutes, a technical consulting service system for hydroelectric power generation equipment was established to accelerate the transformation of scientific and technological achievements. The third is to provide technical support and services to foreign countries, such as the cavitation test of axial-flow turbines in Tsinghua University, the development of high-head hydraulic turbines in Zhejiang private enterprises, and the model acceptance tests for export projects in Fujian Nanping Electrical Machinery Factory.

The research results have also been applied to the Longmentan II power station and the Sanjiangkou hydropower station in Yunnan, and established a strategic partnership for technical transformation and technical support with more than 20 medium-sized power generation equipment manufacturers. The efficiency of turbines and the stability of turbines under market economy conditions require escalation of technological sources and technologies.

At present, the use of scientific research results from the National Laboratory has completed the upgrading of 30 small and medium-sized hydropower stations, including the reconstruction of 6 international hydropower stations; completed 5 types of small and medium wheel model spectrum engineering, industrialization promotion This will further increase the competitiveness of China's hydropower equipment in the international market.

The talent training platform uses the national laboratory as a technology platform to cultivate and cultivate high-level technical research, management, and management talents that are market-oriented, familiar with technology, production, and applications, making it an important base for personnel training.

Harbin Motors attracts talents from home and abroad to the laboratory for research through various methods such as internal induction and outreach, technical lectures, and course training. A powerful technical team has carried out 54 research projects on key technologies for hydro-generator units, pumped storage, power generation equipment, and test technologies in the past three years. Among them, five are national science and technology support programs and 49 are industries. Research projects, the results of some scientific research projects have reached the international advanced level, won the national, provincial and ministerial level scientific progress award.
