The Chief Professional Technical Expert of Southern Power Grid Corporation, Director of DC Transmission Technology, Rao Hong.
Southern Power Grid Corporation is available on November 18th, the Chinese Academy of Engineering announced that the list of candidates in 2021, the Chief Professional and Technical Expert of Southern Power Grid, Rao Hong, director of the National Key Laboratory of DC Transmission Technology, was elected as Academician of the Chinese Academy of Engineering.
For more than 30 years, Rao Hong has always been rooted in the first line of scientific research technology, engaged in power system research, DC transmission design and major engineering construction, DC grid operation technology. He led the DC transmission technology team to create a number of special high pressure flexible DC technology, leading the innovation of DC transmission.
In his opinion, scientific research has no routine, the right technology route, teamwork, professional cooperation is the exclusive "secret" of scientific research.
Strive to be a self-reliant practitioner, "External project manager told me that debugging immediately begged, please leave the staff." After many years, Raohong recalls the scene of Tianguang DC project power-on debugging the scene is still alive. In the purpose. At the beginning of the 21st century, the national Xidong Dongfeng sent strategy kicked off.
In order to continuously send a large-scale large-capacity western cleaning power source to the eastern part, DC transmission is the best technique. However, in my country, six high-voltage DC projects were all households. In 2000, the first DC project of Southern Power Grid-Tianguang DC Project was built and put into operation, the full set of projects introduced foreign products, and the engineering autonomy rate was almost zero.
When the engineering power-on commissioned, a "unrelated personly invited the field", let the Chinese technical personnel in the scene stunned, and let Rao Hong realize that the real core technology is not available.
In 2005, Guigui two returned to ± 500 kV DC transmission line construction, which is the first independent design of DC transmission project in China. As a head of the design technology, Rao Hong is a little bit of speaking. "At that time, the pressure was really large, because all designs such as design software, main loop structure, and equipment parameters were completed by us, and a little error will cause huge losses to the country.
"Two years later, the research team came out of the autonomous road from the research information of the mountain, calculated the draft and experimental record, and came out of the DC transmission technology to be subject to people’s dilemma. The comprehensive autonomy rate reached 70%, of which the set design reached 100%.
Achieving the original innovation from 0 to 1 is the most often said that it is bold and innovation, careful attention.
We must dare to make new ideas, but the technical solution given must be a bamboo. "The researcher of the South Net Research Institute said." Encouragement and innovation "is not the sky, innovation is often coexisting with risk.
In particular, the construction of the power grid is a huge project. If there is an error in system parameters, key equipment norms, etc., it is often equivalent to the whole body, which may cause difficult to estimate. At the end of 2020, the world’s first special high pressure flexible DC transmission project – Udao Electric Station Power TV Guangdong Guangxi Special High Voltage Multi-Delive DC DC DC DC DC DC Model Project ("Kunliu DC Project") successfully put into production.
The production of Kunlilong DC project is an important milestone in the history of technology development technology technology. It has formed an independent intellectual property system in the "card neck" problem, showing the top level and energy equipment manufacturing of China Electric Power Industry Technology. Core competitiveness. Special high pressure, large capacity, overhead line, mixed DC, multi-end, these five keywords are the largest technological innovation points. Since 2016, Rao Hong leads the project team to rely on national key research and development plan – high-voltage large-capacity flexible DC transmission key technology research and engineering demonstration application to carry out joint research, five years, combined with the project, from systematic analysis, parameter selection The devices and demonstrations of the control strategy have given a complete set of technical programs, "implementing the original innovation from 0 to 1."
As the study, Rao Hong and his leading research team gradually found that the problem of unknown areas came one after another, the more it faces unknown, the more necessary determination is supported.
Before the Qunlong DC project was commissioned, Rao Hong and his team have already launched many "simulation run exercises", and each idea has experienced countless considerations, tests.
"He often reminds us to stay with any dead ends and blind spots. Some important reports, he will also check, make amendments, to ensure that there is no loss.
"The team member said. Eventually, in this project, Rao Hong led his scientific research team in the Kunli DC project in the first high-voltage flexible DC technology, realizing the original innovation from technical ideas to engineering technology, leading the global special High pressure technology entered the flexible DC era, affected future grid development pattern. Brought a strong team of fighting power, "The power grid is like the human body’s meridians, there is electricity, so we have to create a strong grid for the people. .
"Rao Hong often said.
Behind a strong grid is a strong scientist team. In the past 30 years, Raohong has been rooted in the first line, insists on the team wants together, dry together. "He will care about the difficulties encountered by the team, and it will often work with us to add some discussions." A member of the team said. At the same time, Raohong attaches great importance to the cultivation of young experts. In major scientific research, in engineering, the Youth Technical Orthodox Party will pay attention to the burden, it also gives the opportunity. "You need to investigate and interfere with scientific demonstration, give scientific recommendations." Rao Hong often said that it is necessary to support youth researchers to support a technical priority work environment, bring out a strong DC transmission youth technical expert team.
Under his leadership, the team has built 3 national innovation platforms, 8 provincial-level innovation platforms, and innovating "self-organized" form new research and development by launching the "Higher Mount" "Climbing Plan" and other talents training plans. The team, exploring the implementation of postal dividends and projects, etc., and actively creates a good working environment for "technical speaking" with techniques.
"As the academician cultivated by the party and the people, we must take advantage of the self-improvement of science and technology.
"Rao Hong said that the next stage will continue to do its own research work, service" double carbon "target, adhere to the innovation lead, strengthen research research on the field of front-edge technology and application technology, and speed up the construction of new energy as the main body Power Systems.
It is also necessary to use science and technology to self-strong as a mission, promote the innovation of institutional mechanisms, and cultivate more first-class scientific and technological talents, and create more excellent engineers.
