Study on Mathematic Simulation of VSCF Electric Power Generating Systems

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.
