Application of asynchronized generators (ASG) in distributed generation plants allows to obtain the following positive results: increase stability margins; expand reactive power adjustment ranges; simplify processes of synchronization to line due to possibility of frequency and EMF phase control; ensure the unit’s operation in synchronous mode when one of excitation windings is damaged. The work provides description of the developed ASG computer model and the system of excitation automatic control. The studies are conducted in the MATLAB system using the Simulink and SimPowerSystems software packages. Emergency modes were simulated for the mains with ASG-based distributed generation plants in conditions of inferior power quality. ASG influence on emergency modes and levels of harmonic distortions in the mains were determined.
