Implementación de mensajería Goose bajo la norma IEC61850 en relés Sel para esquemas de protección de barra

Abstract

This work has the purpose of providing to the electric power engineer, the necessary knowledge to implement the command IEC61850 into the relays of the brand SEL, due to the trending that exist nowadays about the automation and interoperability of the equipment of the electric substation; and a noticeable growth in the use of this brand at the new substations in the Ecuador.In the following work we expose a methodology, for the solution to a typical problem of an undesirable operation into a busbar protection system. We propose a protection scheme of busbar simple, based on the application of the logical programming techniques that every modern relays has (numerical relay) and the messenger service GOOSE (Generic Objetc Oriented Substation Event) based into the command IEC61850, used for the exchange of the protection signals of all the relays that intervene in the protection system, in such a way that it determinates if the failure in the system is found in one of the output feeders or in the bus. Proving that with the recent technology and the implementation of GOOSE messages we could provide a real time system control, making scans of the net each time that occur an incident, guaranteeing the reliability and selectivity of the protection scheme and all the Electric Power System (EPS).
