Sažetak

Various faults in ship’s electrical power system, primarily those connected with diesel-generators, governors and automatic voltage regulators, may lead to oscillations in generator load, voltage and frequency. If those transients are large enough, a partial or total blackout may occur. In order to prevent such events, it is very important to get an insight into dynamic behaviour of electrical energy sources on board vessel. In this paper, a dynamic model in the time domain of marine diesel-generator is presented. The model is realized in the MATLAB/SIMULINK environment and consists of three main parts: the synchronous generator model, diesel-engine governor model and voltage regulator
model. Simulation of a sudden loss of one generator when two generators are running in parallel is performed. Simulation results show that the presented model is fully applicable for the purpose of analysis of the marine diesel-generator dynamic behaviour during transient periods.
