Abstract:

The aero-engine, with the multi-electric technology as its new feature, optimizes the system’s multiple energy architectures and significantly improves system maintainability and reliability, which is now a core component of the multi-electric aero-engine research field. As the power generation system jumps from the hundred kW level to the MW level, the high-power, highly integrated multi-node power distribution system and the power-using system including high-power pumps and actuators together constitute a complex multi-electric control system. This system is characterized by multi-nodes and superposition of dynamic and static changes, and is facing the challenges in different application environments. Based on the electrification foundation, this paper firstly classifies the source-grid-load architecture of the aero-engine multi-electrical control system, and elaborates on the basic concepts, compositional characteristics, and challenges of the source, grid, and load systems. Then, the source-grid-load integrated system is analyzed, and the research status of four key technologies, the lightweight and high-reliable motor technology, power conversion topology and motor drive control, multi-node microgrid networking and control research, and electromagnetic compatibility modeling analysis and suppression methods, is comprehensively analyzed. Finally, the development trend of source-grid-load system and the layout of multi-position architecture are summarized and the prospects are discussed to promote the development of aero-engine multi-electrical control system.
