Power quality research in a modern mediterranean marine

The paper presents results of power quality (PQ) analysis of a Mediterranean marine electric supply in Montenegro. Impact of the marine activity on public distribution network and mutual impact some consumers into marine are analyzed in details. The analysis is performed in three main steps: 1. One week PQ (harmonics) measurements in real operating conditions; 2. Developing of a simulation model of the marine based on obtained measurement results.; 3. Designing a filter for harmonic mitigation using the simulation model. Measurement were performed according to EN50160 standard. Simulation model was designed in special software for power systems analysis, PSS VIPER. The measurement results were analyzed and compared with simulation ones. A good accordance has been reached. At the end, the effects of filter application on harmonics levels are presented and discussed.
