China's Largest Power Supply System Hardware-in-the-Loop Simulation Platform for Fusion Enters Trial Operation and Passes Final Acceptance

en.Wedoany.com Reported - On October 26, China's largest hardware-in-the-loop simulation platform for power supply systems in the fusion field was officially put into trial operation and passed final acceptance. Its comprehensive performance has reached the leading level among comparable international platforms, marking that China has established a complete technical chain from algorithm research and development for fusion power supply systems, through hardware-in-the-loop simulation verification, to the implementation of complete equipment sets.

It is reported that the platform, built on a fully independent real-time simulation architecture, achieves a core solving step size of up to 0.8 microseconds under operating conditions with more than 10,000 model switches. Following comprehensive inspection and review by an expert panel, all performance parameters of the platform's full-chain software and hardware met the predetermined design specifications, and all system construction tasks were completed with high quality.

After the platform is put into use, it can shorten the research, development, and commissioning cycle of fusion special power supplies by more than 40%, significantly reduce the number of physical prototype iterations, and simultaneously support parallel verification of special power supply algorithms with different parameters and different topologies. It can precisely capture the nanosecond-level transient processes of fusion power supply switching operations, fully matching the verification requirements of extreme dynamic operating conditions in fusion scenarios, and comprehensively adapting to the customized testing needs of multi-route fusion experimental devices.

The platform is a landmark scientific research achievement of China Fusion Energy Co., Ltd. under China National Nuclear Corporation (CNNC) after years of deep cultivation in the field of fusion special power supply verification. Its core technologies are fully independently controlled, and underlying secondary development permissions are open to fusion research teams to explore cutting-edge technologies such as AI intelligent optimization and digital twins for extreme operating conditions. Next, the team will take the platform's implementation and commissioning as a new starting point, continue to focus on tackling key challenges and strive at full speed to provide key platform support for China's controllable nuclear fusion power supply systems to achieve full-chain independent controllability.
