摘要
建立了脉宽调制型交直交变速恒频电源系统的数学模型,研制了仿真软件,并给出了仿真实例.研究表明,本文的方法和软件可以进行变速恒频电源系统部件级和系统级的仿真分析,为设计和分析该系统提供了有力的工具.文中的方法和软件也可以用于分析恒速恒频和高压直流电源系统,为开发一套完整的飞机电源系统仿真软件奠定了基础.
The pulse-width-modulation DC link variable speed constant frequency (VSCF)electric power generating systems (EPGS) are the important trend in modern aircraft ACEPGS. Mathematic simulation can be used to analyse the steady state and dynamic characteris-tics of EPGS, to research the relationship of parameters of every parts, to select the design da-ta and to analyse the trouble shooting. The mathematic model of DC link VSCF system hasbeen established. The simulation software has been developed and simulation examples havebeen made. The research shows that the simulation software and method developed can beused to both the components and the system for the simulation of VSCF systems, and have be-come a powerful equipment to design and analyse the VSCF systems. The method and soft-ware also can be used to analyse the CSCF EPGS and the HVDC EPGS. A foundation hasbeen established to develop a set of softwares of analysis and design for aircraft electric powergenerating systems.
