National Load Dispatch Centre

The project involves supply and installation of OPGW/ADSS OFC on over 2500 km of existing 132kV transmission lines replacing existing earthwire, integration with OFC on existing 230kV Transmission lines, and provision of an SDH STM-1/4 backbone transmission network over this infrastructure. The telecommunication network comprises a STM-4 transport layer linking 6 primary SDH loops with subnetwork (SNC) and redundant multiplex protection. The network provides 10 Mbits/Ethernet services to all SCADA RTUs, IP Telephones, provides primary protective relaying channels and supports a large administrative telephone system with 20 state of the art digital telephone exchanges (SOPHO), Over 110 substations and generating stations are linked via RTUs to a comprehensive SCADA/EMS system. Existing SCADA and Automation system will also be connected to NLDC. SCADA. Protection and telephone services are backed up over the existing PLC radio network. The telecommunication network also comprises STM-1 microwave link between two stations, Trunk Mobile Radio network for service purposes and underground OFC cable for linking some stations. The main and back control centre comprises with HP servers, workstations, Cisco Router, switch, IP telephone, Cisco Call Manager, Philips SOPHO telephone exchange etc. This project was funded by ADB and the contractor for this project was Consortium of Areva, France & Furukawa, Japan. The project cost was about $100 million US dollar.
