Reconfiguración de los esquemas de protección y control mediante relés alfanuméricos para modernizar la Subestación Norte de la EEQ.SA.

摘要

Substations of EEQ.SA were designed and built with electromechanical control equipment and protection since the time when it was installed the technology, these teams census failure to send a disconnect signal to de-energize the electrical system power they are protecting, as a record of its operation have electromechanical only signaling phase in which the fault occurred, this does not allow to know the magnitude of the current that is provided to activate the relay, not to determine the time at which recorded failure information that would be useful to improve the maintenance program. The constant development of technology has demanded that implement and adjust control systems and protection alphanumeric relays, either system requirements or simply because of the absence in the market for a computer of the same type for replacement, creating a mixing technologies
