Monitoring of Power Quality at Small Hydropower Plant ? Case Study

Boris CFARKU ^[2] | Nako HOBDARI | Astrit BARDHI ^[3]

Abstract: In recent years, the interest of building small hydropower plants by operators working in the field of energy production in Albania is increased. These generations unit, which usually are connected at medium or low voltage line transmission of power system are built in all Albanian area and not coordinated with planning of distributed system. Due this reason, small hydropower plants in some cases have been caused some problem such as overvoltage, overloaded of transmission line, switch off of power line etc. The capacities of transmission line are limited and often the new hydropower generations are forced to work with under their capacities. In this paper, we have presented the data of monitoring of a small hydropower station and analyzed them in order to find the reasons that caused anomalies and the ways to overcome them. Based on the analysis we recommend that in the substation must be installed power transformer and building new transmission lines are necessary in order to create ring/loop system instead of radial distribution system.
