Resumen
This present study develops a proposal to upgrade protection functions of various Intelligent Electronic Devices (IED’s) with digital technology, which protect generators and transformers of Saucay, Saymirin, El Descanso and Ocaña power plants belonging to Elecaustro S.A.
Also a proposal to activate new protection functions is made, especially on Saucay, Saymirin III, IV and El Descanso plants, where electromechanical relays were replaced by IED’s in the past.
To know which protection function needs to be updated or activated, it is carried out a comparison between the recommended protection functions by the standards: IEEE Std C37.102-2006 for AC generator protection, IEEE Std C37.91-2008 for transformer protection and the protection functions that currently have the installed IED’s.
Also a new proposal for coordination of overcurrent functions that protect generators, transformers and transmission lines is performed, considering that all plants belonging to Elecaustro S.A are embedded in the 69kV subtransmission system belonging to EERCS.
Finally, with the help of the software DIgSILENT PowerFactory, various failures are simulated at different points of the grid to make a contrast between existing and proposed trip times.
