Experimental stand-alone self-excited induction generator driven by a diesel motor

This paper presents an experimental work to design and size a diesel generator (DG). The basic system is equipped with a 1.5 kW self-excited induction generator (SEIG), a diesel motor (DM), a static voltage compensator (SVC) and controllers. A proportional integral controller is used to meet the requirement of the SEIG frequency regulation. A controlled voltage source is performed by using an SVC with a fuzzy controller, which adjusts voltage by varying the amount of the injected reactive power. An experimental set-up is used to identify the SEIG parameters and select the convenient bank of capacitors that minimize the SEIG starting up time and fix the convenient margin of voltage. The system has been tested by simulation using models implemented by Matlab/Simulink software. The simulation results confirm the efficiency of the proposed strategy of voltage regulation.
