Abstract :
This paper discusses the steady-state analysis and performance of self-excited induction generators (SEIG) driven by regulated and unregulated turbines. For constant-speed operation, a simple technique is used for the determination of the electrical frequency. Where for SEIG driven by an unregulated turbine, The turbine characteristics and the SEIG speed-torque characteristics are experimentally verified. The effectiveness of the suggested method and experimental results are compared with MATLAB simulation. Experimental investigations on a 1.5-kW three-phase induction machine confirm the accuracy of the proposed methods of analysis.
