Design of an underwater oil-electric hybrid energy storage and replenishment system

Underwater operating platform has the typical characteristics of complex energy system, and its energy supply efficiency is significantly different from the traditional single energy system. Existing researches mainly focus on specific energy types or independent subsystem design, and lack of systematic research on the overall synergy of oil-electric hybrid energy systems. This paper first clarifies the working principle and workflow for the requirements. From the perspective of complex system engineering, the framework of underwater hybrid oilelectric energy system is constructed, and the functional relationship between energy storage unit, energy conversion device and dynamic supply interface is deconstructed based on modular design. Then, the technical and construction risks are analyzed, and the special design is carried out for the specific working conditions, and the overall design of the system is finally realized. The research results provide a new technical path for the design of hybrid energy systems for complex underwater operating systems.
