INTEGRATEC'S SYSTEM IN LUZ Y FUERZA DEL CENTRO

Luz y Fuerza is a state-owned utility that handles all the power distribution to Mexico City and the metropolitan area. It serves a population in excess of 23 million people.
Electricity is supplied by the Comisión Federal de Electricidad (CFE) using a 400KV ring. LyF then uses 230KV, 115KV and 85KV sub-rings to distribute the power to the urban 23KV system.
LYF handles the distribution using 214 sub-stations and has the capacity to distribute up to 8,000MVW.

PROBLEM DESCRIPTION AND SYSTEM REQUIREMENTS:

Most of these sub-stations are old and not automated, LyF has an ambitious program to modernize the infrastructure and automate most of the operation at the sub-station level.

Integratec de México developed a solution for the automation of sub-stations in LyF. This solution is based on the RealFlex SCADA system and has been in use in several stations since the mid 90s. There are three layers of control in the system, Integratec is involved in the first two (see diagram). LyF has standardized in Integratec's solution and now all new sub-stations that are being added to the system include the Integratec system.

LyF plans to automate up to 20 sub-stations per year until the whole system is updated.
