Abstract:Shipboard Integrated Power System (IPS) represents the third revolution in marine power platforms. It realizes unified energy management and control by combining power generation, daily load supply, propulsion, high-power pulse supply, and intelligent energy distribution. With the rapid development of shipboard IPS, the system has faced many serious challenges, including complex system protection, a strong demand for high-capacity, fast-response energy storage, and high requirements for high power density and high efficiency in propulsion devices. High-temperature superconducting (HTS) technology offers low loss, high current density, small size, and light weight, which is a new approach to overcoming the performance limits of traditional electrical equipment in shipboard IPS. This paper first introduces the structure, technical features, and key challenges of future shipboard IPS. Then, regarding key IPS equipment, this paper reviews global research progress, technical benefits, existing shortcomings, and major challenges across seven aspects: second-generation HTS materials, HTS motors, superconducting magnetic energy storage, flywheel energy storage supported by superconducting magnetic bearings, superconducting cables, superconducting fault current limiters, superconducting wireless charging, and the combined application of superconductivity with other energy sources. Then, this paper discusses the key problems that require urgent attention. Regarding improvements in economic efficiency, functional integration, and near-limit design capability, three main obstacles are identified: an unclear HTS quenching mechanism under extreme working conditions, insufficient multi-physics coupling design ability for operating superconducting equipment, and poor reliability of cryogenic cooling systems. Finally, to meet the demand for high-efficiency energy use in future shipboard IPS, this paper proposes a development plan for HTS-based shipboard integrated power equipment. It also summarizes key common technologies and potential solutions, providing a reference for the engineering applications in future IPS and unmanned marine equipment. The results show that HTS devices can greatly improve the performance, efficiency, and power density of key equipment. This equipment includes propulsion motors, power cables, energy storage systems, and wireless charging devices. HTS technology also helps reduce equipment size and weight and improve installation adaptability. However, the large-scale engineering application of HTS technology still needs technological breakthroughs, including in situ testing of HTS materials under extreme conditions, multi-physics coupling and near-limit design of superconducting equipment, and high-reliability design of cryogenic cooling systems. Digital twin and intelligent monitoring technologies support the smart operation and optimal management of superconducting facilities. Furthermore, advanced superconducting materials and near-limit system design can realize the application potential of high-temperature superconducting equipment. The combination of artificial intelligence, digital twin, and near-limit application of superconducting materials will effectively promote the engineering and large-scale application of HTS technology in future shipboard IPS.
