FGI has ensured the zero-fault operation of the National supercomputing center for over 1,700 days
1.Background
National Supercomputing Center
Today, with the explosive growth of computing power driven by artificial intelligence technology, global data centers are experiencing a period of rapid expansion. The National Supercomputing Center in Jinan (hereinafter referred to as "Jinan Supercomputing Center") was approved by the National Science and Technology Department and is a comprehensive research center engaged in the research and development of intelligent computing and information processing technologies as well as computing services. It is also the birthplace of China's first supercomputer that fully adopts domestically developed processors and achieves a trillionth operation. It has successively built supercomputers such as Shenzhou Blue Light, Shenzhou E-Class Computing Prototype Machine, Shanhe Super Computing Platform, and Shenzhou·Blue Light II. Its comprehensive computing power ranks among the top in the world, promoting supercomputing from research to industry, and leading the development of the world's supercomputing industry into the 2.0 era. Jinan Supercomputing Center has continuously served over 3000 units of research institutes, high-tech enterprises, government agencies, etc. in fields such as weather forecasting and climate prediction, marine environment simulation analysis, information security, industrial simulation, engineering computing, financial big data analysis, new materials and new energy analysis, etc. It has truly become a computing power engine for the development of major projects such as new and old kinetic energy transformation in new and old industrial sectors like new-generation information technology, medical and elderly care health, high-end equipment, new energy and new materials, and smart ocean in the province and even the country.
2.Join hands with major projects to promote in-depth integration
As an important scientific research infrastructure, the power supply reliability of the Jinan National Supercomputing Center is of utmost importance. The center is supplied with power through a 110kV dedicated line. To ensure the stable and efficient operation of the entire power supply system in the park, FGI Company specially designed two sets of 10kV/6Mvar high-voltage dynamic reactive power compensation system solutions. These two sets of SVG devices are respectively deployed on one busbar and another busbar of the center's power distribution system. They adopt advanced IGBT power modules and instantaneous reactive power theory control technology, enabling rapid response in milliseconds and dynamic compensation of the system's reactive power. Since its commissioning, this system has continuously operated stably for over 1700 days, successfully increasing the power factor of the park's power supply system to above 0.98, effectively reducing line losses by 15%, and providing a strong power guarantee for the scientific research work of the supercomputing center.
3.Sunshine Service Initiative, deepening customer cooperation
Recently, there has been a persistent hot weather. To ensure the stable operation of the customers' equipment, FGI Company organized a professional technical team to carry out a special "Sunshine Service" follow-up visit campaign. The technical service team went deep into the customer's site, conducted a comprehensive inspection of the equipment's operating status, meticulously identified potential risks, and provided professional maintenance and care for the equipment. At the same time, for the technical questions that customers encountered during use, the technical service personnel provided one-on-one solutions and professional technical guidance to ensure that FGI'SVG could continuously maintain its optimal operating performance.
4.The power supply system is facing challenges
Voltage flicker: Intensified instantaneous power fluctuations leading to voltage fluctuation risks;
Harmonic pollution: The superimposed effect of harmonics caused by nonlinear loads;
Load mutation: The response speed of reactive power compensation is difficult to match the dynamic changes of the load.
5. Compared with the traditional LC filter + SVC compensation scheme, the high-voltage SVG has obvious advantages:
Millisecond-level dynamic response, achieving 100% reactive power compensation within 10ms, perfectly matching the second-level fluctuation characteristics of AI loads.
Precise harmonic control, automatically detecting system harmonics and promptly compensating for and managing them, ensuring the purity of the power supply waveform for precision chips.
High power density, with a smaller footprint for the same capacity, saving space.
Stable compensation capacity, less affected by system voltage fluctuations.
Flexible configuration options, adaptable to on-site application requirements.
6.Looking to the future, comprehensive solutions
Based on its core technological advantages, FGI continuously leads the forefront of power electronics integration innovation, and can provide comprehensive solutions such as power quality management, motor frequency conversion energy saving, and energy storage emergency power supply for global data centers. It not only offers outstanding intelligent power quality guarantees, but also builds the core support for the future data center power system. FGI uses forward-looking technologies and overall value delivery to help enterprises lay a solid digital foundation and accurately seize the strategic development opportunities bestowed by the AI era.
