Simulation of dynamic modes of power supply systems equipped with diesel generators, at inferior power quality

The article provides results of studies aimed at implementation of power supply systems (PSS) computer-based models in conditions of inferior power quality, where the PSS include backup diesel generators. The main aim of the study was to research these generators synchronization with the PSS network. The simulation was performed in the MATLAB environment using the Simulink and SimPowerSystems software packages. Based on the results obtained, it can be concluded that the self-synchronization method can be used for turning on diesel generators for parallel operation with PSS. After the synchronization processes completion, an improvement in the quality indicators of electricity in the PSS network and at the interfaces with the power supply system in terms of asymmetry and harmonic distortions.
