No.49International Exhibition of Inventions of Geneva（International Exhibition of Inventions of Geneva）Yu2022Year3month16Sunday20Held on Sunday。The "Wind Turbine Digital Twin System" and "Wind Farm Digital Twin System" projects completed by the team led by Professor Zhao Haoran of the School of Electrical Engineering both won silver medals in the competition，This is the first time our institute has won the honor of this international invention exhibition competition。
The "Wind Turbine Digital Twin System" project is aimed at the current situationUnit design、Refined simulation、Problems in operation and maintenance and other work，Developed a unit-level digital twin software and hardware system，Refined digital mapping of units has been achieved。The R&D team proposed a high-precision unit simulation model that considers multi-physics coupling and full life cycle characteristics，Developed a heterogeneous real-time hardware simulation platform and host computer software、Three-dimensional dynamic model and other software systems。This project can assist wind power equipment manufacturers in unit structure and control system design、High-precision real-time simulation、Operating status monitoring and analysis、Energy Efficiency Assessment、Intelligent diagnosis and other work，Has broad application prospects。
The "Wind Farm Digital Twin System" is a complete software and hardware solution for realizing digital mapping of wind farms。It can accurately capture the main dynamic characteristics of the wind farm on a wide scale，Including inter-unit wind field aerodynamic coupling (wake effect)、Electrical coupling (concentrated system) and information coupling (control system)。simultaneously，The system has the ability to interact synchronously with the actual wind farm，Wind farm parameters can be updated and corrected in real time based on measured and simulated data。This system can assist wind farm operators through optimized operation control throughout the life cycle，Increase power generation、Realize intelligent operation and maintenance；Can assist the grid to reproduce and analyze wind farm grid connection stability issues，Promote in-depth research on high-proportion new energy power systems。
The International Exhibition of Inventions of Geneva was founded in1973Year，By the Swiss Federal Government、Geneva Cantonal Government、Co-organized by the City of Geneva and the World Intellectual Property Organization，It has the longest history in the world，The largest invention exhibition。2022, due to the new crown epidemic, the invention exhibition was changed to online judging, total 25 approximately countries and regions 800 projects participated in the exhibition.
