Power quality in distributed generation system based on fuel cell technology - a case study

This paper presents a case study involving one of the main technologies of distributed generation - dg, commercially available, fuel cell, focusing the aspects related to the quality of the electric power supplied by such devices, especially harmonic and voltage imbalances, the measurements and evaluation were made in a fuel cell, PC25C™, 200 kW power plants, based on phosphoric acid fuel cells, installed in the LACTEC facilities, in Curitiba, PR, Brazil. Finally, the work will present the main obtained conclusions, indicating the main aspects of power quality, which must be considered in the application of this device to distribution networks.
