[China's largest fusion power supply system semi-physical simulation platform was put into trial operation and passed final acceptance] On October 28, CNNC revealed that China's largest fusion power supply system semi-physical simulation platform was officially put into trial operation on October 26 and passed final acceptance. Its comprehensive performance has reached the leading level of similar international platforms, marking that China has established a complete technology chain from fusion power supply system algorithm research and development, semi-physical simulation verification to the implementation of complete equipment. It is reported that the platform relies on a fully autonomous real-time simulation architecture, and under operating conditions with more than 10,000 model switches, the core solution step can reach up to 0.8 microseconds. After comprehensive verification and review by the expert group, all performance parameters of the platform's full-link software and hardware have reached the preset design indicators, and all system construction tasks have been completed with high quality. After the platform is put into use, the R&D and debugging cycle of fusion special power supplies can be shortened by more than 40%, significantly reducing the number of physical prototype iterations. At the same time, it supports parallel verification of special power supply algorithms with different parameters and topologies, can accurately capture the nanosecond-level transient process of fusion power supply switching actions, fully matches the verification needs of extreme dynamic conditions in fusion scenarios, and fully adapts to the customized testing needs of multi-route fusion experimental devices.
