Resumen
OLALDE ESTUCH, Rasiel; TORRES BREFFE, Orlys Ernesto; ESPINOSA DOMINGUEZ, Julio y CABALLERO MENA, Alvaro Jesús. Improvement to the Generators Sets Protections of MAN technology. Study of case Ariguanabo. Energética [online]. 2021, vol.42, n.1 Epub 01-Mar-2021. ISSN 1815-5901.
The electrical protections of Fuel Oil Ariguanabo generator set not working appropriately. Total breakdowns have ocurred in the engines and generators as well as numerous unnecessary protection trips due to external faults. Using mathematical modeling, the main faults were simulated with the new relays settings, in addition new protection functions were added to obtain new proposed protection strategies. The internal logic of the relays were modified. At present the PLC no longer participates in the protections ruth of trips and not all the faults disconnect the engines but some of them trip only the generator circuit breaker. All this problems mencioned are the same in other electrical generator central of the same MAN technology because the original project are identic and there for, this solution are totally applied in those centrals.
