In addition to highly trained, skilled and experienced man power, National Grid Dispatching (NGD) department makes extensive use of dedicated telecommunication infrastructure, developed and operated within the electric power industry, with primary purpose of providing necessary services for Monitoring and Control (Dispatching) functions.
The SCADA/EMS facility at national System Control center (SCC), and Area Operating Centers (AOC) in nine regions in electric power transmission network, provide NGD with necessary hardware and software tools and applications to perform its tasks and discharge its responsibilities through a decentralized hierarchy of “Monitoring and Control” (Command and Control) procedures (Fig. 3).
There are plans for upgrading and replacement of the existing SCADA/EMS facility in the System Control Center with a state-of-art technology, employing advanced functionalities and capabilities. The overall architecture of the new SCADA/EMS/WAMS and the two concurrently active control centers (national System Control Centers (SCC) and Backup System Control Centers (BSCC)) is based on a centralized approach to monitoring and control procedures.
