Field-Circuit Modelling of Self-Excited Induction Generators
Abstract
In the paper computational models of aninduction self-excited generator are presented. Circuit
models taking into consideration nonlinearity of the
magnetic circuit enable calculations of the generator static
characteristic at an autonomic operation. The field-circuit
model using Maxwell 2D software allows determination of
time curves of any electrical variable in different conditions
of the generator operation. There are presented basic
determined static characteristics using both models and
time curves of currents, voltages, torque during self
excitation and under symmetrical load and one-phase short
circuit, in cooperation with a rectifier system and during
connection of the excited generator to network.
