The power grid simulation technology began to output continuously. On June 15, China Southern Power Grid Research Institute and Brazil National Power Dispatch Center formally signed the “Multi-DC Feeding System Simulation Analysis Technical Consultation” cooperation agreement. According to the agreement, China Southern Power Grid will A one-year HVDC power transmission technology training was carried out. This is followed by real-time simulation training and exchanges with technical personnel of the Korea Electric Power Institute, and will once again undertake international business by directly signing foreign-related contracts, which fully demonstrates China's power grid simulation technology. international influence.
Large grid simulation technology
Luis Blatar, president of Brazil's National Electric Power Dispatch Center, said that similar to Brazil’s grid and South Grid’s grid structure, long-distance and direct-current projects are needed to connect the sending end and the receiving end. China Southern Power Grid is very experienced in DC operation. Hopefully, In the future, China Southern Power Grid can share its HVDC transmission operation experience and make progress together. According to reports, HVDC transmission technology is widely used in Brazil's power grid. It is expected that by 2024, Brazil will form a 8-10 dc centralized deposition point in Rio and São Paulo region. The southeastern regional network of the South China Sea has its grid characteristics very similar to those of the South China Power Grid. It also has features such as parallel operation of AC and DC, multiple DC infeed, etc. It faces technical challenges in system operation, simulation analysis, and security prevention and control.
At present, China Southern Power Grid has formed eight channels of eighteen straight and ten straight routes from West to East. The scale of power transmission exceeds 47.5 million kilowatts. The main grid adopts AC and DC hybrid operation. It has become one of the most complex power grids in the world. After years of in-depth Research and analysis, China Southern Power Grid has formed the world's most advanced and complete HVDC transmission technology and AC/DC complex large-scale power grid operation analysis technology, creating a number of world firsts.
