To serve industrial customers in the Monterrey,
México area, Iberdrola Energía Monterrey completed a project
that consisted of building five 115/13.8 kV substations, several
115 kV lines, and the protection and control system for the
115 kV and 13.8 kV networks. In this paper, we describe the
protection and control system of the 115 kV network, which uses
multifunction relays with communications and logic
programming abilities. We describe an adaptive protection and
control logic that allows operators to reconfigure the network for
some permanent faults and adapts relay settings to the new
network configuration. We show the results of a PCS factorystaged
test, provide system operation statistics, and describe the
protection scheme operation for an actual fault event.
