DSP control of variable speed integrated generator

This paper is focused on the industrial development of a novel type variable speed power generating system that can be used for the supply of electrical loads in the range 10 kVA to 100 kVA. Variable-speed-integrated-generating (VSIG) sets consist of a diesel engine, an axial type permanent magnet generator and high frequency power converter that is IGBT based. The axial type PMG has proved to be the best candidate for variable speed application. The unique feature of the control system based on DSP ensures fast system response to load application, accurate mapping of engine torque with load current and is a very versatile platform. The high quality sinusoidal output voltage from VSIG sets under different load conditions is presented.
