New Variable Speed Integrated Generator for stand alone and support power generation

This paper is to present a novel type of variable speed power generating system that can be implemented to supply electrical loads in the range of 5kVA up to 100kVA. The Variable-Speed-Integrated-Generator (VSIG) set consists of a diesel engine, an axial type permanent magnet generator and high frequency power converter. The unique feature of the control system based on a robust digital signal processor (DSP) platform with accurate mapping of engine performance characteristic. The controller is optimised for rapid system response to load application and load demand. The high quality sinusoidal output voltage from VSIG set under various load types and conditions will be presented in this paper.
