Excitation of isolated three-phase induction generator by a single capacitor

The author determines the steady-state performance of an isolated, self-excited, induction generator when a single capacitor is connected across one phase or between two lines. The work is concentrated on the case when the machine is supplying one or two loads. With the aid of the equivalent circuit, an analytical technique has been used to obtain nonlinear algebraic equations for operation frequency and magnetising reactance. A numerical solution method is applied to solve the nonlinear equations. Performances for different load configurations, and different load conditions are considered. Where possible, computed results are confirmed with experimental results
