Abstract :
Two methods are presented for the analysis of operation of a self-excited induction generator that also provide a procedure for the computation of the required external capacitance. With this procedure the minimum and maximum values of speed, frequency, voltage, and output power can be easily determined. The analysis is only valid for different steady-state conditions. One method makes use of the basic equivalent circuit of the asynchronous generator and its associated equations, together with the magnetization curve of the machine. As long as the frequency is no longer constant in stand-alone operation, the second method analyzes the generator in the frequency domain, thus making it possible to determine the conditions for self-excitation under different loads.<>
