In the eyes of colleagues, Li Qingsheng likes to taste new things and work rigorously. He is a three-level technical expert of China Southern Power Grid Corporation. He is the deputy chief engineer of the Power Grid Planning and Research Center of Guizhou Power Grid Corporation, the director of the System Technology Research Office and the secretary of the Party branch. He is also the first person in Guizhou Province to “innovate for the first time and science and technology role modelâ€. These positions and honors are not completely familiar to everyone, but many of his colleagues know that he is the head of the National 836 Program and is committed to researching the “Integrated Renewable Energy Active Distribution Network Research and Demonstration†project, striving to break through China. The intermittent optimization of distributed power supply access to the distribution network and the bottleneck of control technology, to demonstrate the application of intelligent distribution network.
Reporting the first national key science and technology project of Guizhou Power GridLi Qingsheng was a small repairer in the community since he was a child. He likes to drum up electronic products. There are nearly 30 small programs, human-computer interaction, database, and drawing programs written in middle school.
He walked to the job with this kind of eagerness. At that time, Li Qingsheng, who was the person in charge of the dispatched duty, was troubled by the inconvenience of scheduling records. He is determined to develop a convenient and efficient dispatch management system. After hundreds of revisions and debugging, the system was successfully developed and went online. The paper data is turned into electronic, which greatly improves the work efficiency. "Innovation is not only to make earth-shattering changes, but more to focus on exploring new ways to improve efficiency." Li Qingsheng said.
After coming to the System Technology Research Office of the Planning and Research Center of Guizhou Power Grid Corporation, Li Qingsheng established a research team for power grid planning technology innovation. In April 2013, when the Ministry of Science and Technology released the “propositional composition†of the research project in the energy field of the National 863 Program, Li Qing vividly declared his thoughts.
While applying to the Guizhou Power Grid Corporation, he led the staff of the department to non-stop to the famous domestic universities and enterprises such as Tsinghua University and Shanghai Jiaotong University to carry out active distribution network technology exchange. Li Qingsheng said that renewable energy has been transformed into centralized large-scale development and decentralized development. It is urgent to study key technologies such as active flow management and active control of distributed energy that meet the characteristics of modern distribution networks. In the end, Guizhou Power Grid Corporation decided to set up a project reporting team by Shanghai Jiaotong University, Tsinghua University and Beijing Sifang, and Li Qingsheng was the project leader.
"Can such a big problem be declared successfully?" "Do our technology keep up?"... In the face of various doubts, he shielded the noise to lead the team to learn advanced technology and carefully organize the application materials.
From the preparation of the project recommendation book to the successful application, it took 10 months for Li Qingsheng to strictly check every link to ensure that it is reported after correctness. In the defense, as the main reply, he repeatedly simulated more than 10 days and nights, finally conquered more than 10 smart grid experts, and successfully won the National 863 Program. This is the first time that Guizhou Power Grid Corporation has undertaken national key science and technology projects.
3 years to overcome 8 difficulties, put forward 4 innovative technologiesIn the past three years, Li Qingsheng led the team to open the work mode of “White Plus Black†and “5+2â€, which solved one problem after another and achieved many zero breakthroughs.
Li Qingsheng organized technical exchange meetings in Guiyang, Shandong, Beijing and other places to study and discuss the best solution for the core part of the project, "Cooperative thermoelectric coupling cooperative control of cold and heat electricity triple-units under active distribution network conditions". In the preparation of the active distribution network demonstration project island and off-grid scheme, Li Qingsheng determined the “big island†experimental scheme of hydropower as the main FM power supply and the “cool island†as the main FM power source according to the characteristics of the demonstration project. "Experimental program. The FCE control scheme in the source-load interaction mode under the island mode is designed, and the distributed power supply and flexible load and the cooperative mode of participating source network load are controlled.
“Director Li led us to overcome 8 difficulties and proposed 4 key innovation technologies.†Tang Xueyong, a member of the research team. In the eyes of team members, the team touched the stones and crossed the river. Overcoming many difficulties was inseparable from the leader who was tireless and dared to attack.
In the end, the project passed the acceptance of the Ministry of Science and Technology. "The subject breaks through the technical bottleneck of coordinated optimization and control of various intermittent distributed power supply distribution networks in China, improves the R&D and innovation capability of intelligent distribution equipment for active distribution networks, and promotes the upgrading of distribution intelligent industries. Relevant experts from the Ministry of Science and Technology said that the research and development results of this project have a strong demonstration role for the application of smart distribution network in China, and have high promotion value and social benefits.
Li Qingsheng believes that the scientific research road is long and still needs to continue to work hard. His wish is that the research results can contribute more to the construction of the smart grid of China Southern Power Grid Corporation.
This scratch-resistant TPU Film protects your new AirTag from daily wear and tear. It can be easily glued to the back to keep the shiny silver in its original condition. In addition, the AirTag screen protector with "self-healing" function can automatically repair small scratches and bubbles within 24 hours. This means you can continuously enjoy the new look and appearance of AirTag without worrying about serious scratches and dents.
The Apple Airtag TPU Film can perfectly fit your AirTag skin. It is designed to provide the maximum coverage for your AirTag metal panels. Compatible with most AirTag shells. Leave extra space around the frame so that your shell can wrap the edges of the AirTag without interfering with the film.
The 0.14mm ultra-thin AirTag Screen Protector allows you to enjoy the maximum resolution while being thin enough to make the AirTag sensitive to the original signal response, ensuring that it will not affect any user experience. You won't even notice that the screen protector is there, so your Apple logo can still be displayed.
The AirTag Tracker Screen Protector is very easy to apply and is specially designed for your AirTag. Just clean your AirTag and install it on the surface to eliminate all bubbles and get the job done!
