The paper presents the analysis of power quality characteristics at the 10 kV grids supplying a modern hotel complex in Montenegrin Adriatic coast. The consumer is characterized with different type of loads, of which some are with highly nonlinear characteristic. For example, smart rooms, lift drives, modern equipment for hotel kitchen, public electric lighting, audio, video and TV devices, etc. Such loads in the hotel complex may be source of negative effects regarding power quality at MV public distribution network (10 kV and 35 kV). In the first part of the paper, results of harmonic measurement at a 35/10 kV substation are presented. The measurements lasted one week in real operating conditions (in accordance with EN 50160). The results were the basis for developing a simulation model. The measurement results were analyzed and compared with simulation ones. Application of harmonic filter is simulated. Filter effects on harmonic level is calculated and discussed using simulation results.
