ipConv enables coupling between a Siemens XMAT control system and the superordinate control stations.
The protocol converters operate redundantly with reciprocal monitoring via the
RS232 connection (R). Communication to the control stations is based on various
26 protocol converters were used to connect 13
stations* at CFE (Comisión Federal de Electricidad).
CFE provides about 85% of the 4,270 MW power in
total which can be fed into the CFE power grid, while independent energy
providers contribute about 15% (as of March 2004). Generated power mainly
originates from combined power stations (approx. 73.5%), hydro power stations
(approx. 21.1%) and atomic power stations (approx. 3.1%).
The combined high, medium and low voltage network covers a total length of
660,852 km (as of March 2003).
