Abstract

Special protection systems (SPS) play an important role in the improvement of power system reliability. SPS help to prevent blackout of power systems. SPS offer other benefits and their use may represent more profits for utilities. For instance, the installation of a SPS can help to relax some constraints for the operation of a power system. SPS offer also benefits to customers. Hydro Quebec used SPS for more than 20 years. This SPS is composed of remote load shedding system and underfrequency relays installed in 140 substations. This system has improved the reliability and robustness of the Hydro Quebec power system. This experience has proved that both utility and customers can get benefits from SPS
