Project description
OETC monitor and control the whole electricity transmission network from their load dispatch centre (LDC) in Muscat. In order to achieve this OETC use an ABB SPIDER SCADA/EMS. 66 substations are connected to their load dispatch centre (LDC) through substation control systems (SCS) with RTUs using the IEC 60870-5-101 protocol.
