摘　　要：舰船或陆用柴油发电机通常采用压缩空气、电起动和液压等专门的起动装置进行机组起动,起动成功后,这些装置停止运行,致使起动装置存在占用空间大、使用率低、效益不高等问题;鉴于无刷同步起动/发电一体化技术在国外航空发动机中的成功运用,本文在对多级无刷发电机电动模式和发电模式运行机理分析的基础上,通过梳理、对比当前国内外提出的单相交流励磁、两相交流励磁、三相交流励磁三种技术方案的优缺点,并对其在柴油发电机中的应用进行了可行性研究,得出了各方案所适用的领域,为后续研究提供借鉴。Ship or land diesel generator usually uses compressed air,electric starting,hydraulic and other special starting devices to start the unit.After successful starting,these devices stop running,resulting in large space occupation,low utilization rate and low efficiency of the starting device;In view of the successful application of brushless synchronous starting/power generation integration technology in foreign aeroengines,this paper,based on the analysis of the operation mechanism of multi-stage brushless generator in electric mode and power generation mode,combed and compared the advantages and disadvantages of three technical schemes currently proposed at home and abroad,namely single-phase AC excitation,two alternating current excitation and three-phase AC excitation,and conducted a feasibility study on its application in diesel generator.The applicable fields of each scheme were identified,providing reference for subsequent research.
