In terms of mechanical design, lightweight materials and structural designs are used. While integrating the permanent magnet array and related power generation components, the weight increase of the rotating body is controlled to a minimum, effectively solving the problem of efficiency loss caused by the weight increase of the rotating body. 2. By proposing a hybrid energy storage frequency division control technology, the different charge and discharge characteristics of supercapacitors and lithium-ion batteries are used to divide the frequency of power fluctuations of different frequencies. Supercapacitors are responsible for responding to high-frequency transient power fluctuations, while lithium-ion batteries mainly store low-frequency steady-state energy. Through precise control algorithms, microsecond-level power response is achieved, while frequent high-current charge and discharge of lithium-ion batteries is avoided, thereby extending battery life. 3. The fault self-diagnosis module can use big data analysis and intelligent algorithms to perform real-time analysis on the data collected by the multimodal detection module, so as to detect system faults in a very short time and accurately determine the type and location of the fault. This not only improves the reliability of the system, but also facilitates rapid maintenance and reduces maintenance costs. BRIEF DESCRIPTION OF THE DRAWINGS
