Coupling of the ALSTOM S900 RTUs to the control center is implemented via
four protocol converters. The ABB protocol ADLP-80 is used for the uplink
communication from the converter to the control station. Communication with the
RTUs is based on IEC 60870-5-101 in balanced mode.
Redundant lines are used to connect the communication terminal devices to the
protocol converter. The protocol converters and telecontrol transformer TCT
are installed at stations #1 - #4.
The Roweis and Abu Kammash stations in Libya are to supply electricity to the
Medenine and Tatouine stations, securing the growing energy demand in neighboring Tunisia. This is achieved with the help of ALSTOM RTUs installed at
these stations and linked to the national Libyan control system via IPCOMM
protocol converters. From here energy distribution will be monitored.
GECOL (General Electric Company of Libya) is the government run electricity
provider and operator in Libya.
Power generation is primarily based on combined power stations (oil and gas). In
1999 Libya generated a total of 19.5 billion KW, 90% of which were consumed.
