Interconnection Libya-Tunisia

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.
