Real-Time Power System State Estimator within the National Control Centre of Serbia

This paper presents detailed architecture and implementation aspects of Network Topology (NT) and State Estimation (SE) applications integration with proprietary SCADA system. Site acceptance test (SAT) of such an integrated SCADA/NT/SE system performed in a real-time environment within the National Control Centre (NCC) of Electric Power Industry of Serbia (EPS) is also described. Test system and test environment are presented further. Finally, achieved results and SCADA/NT/SE real-time operation experiences within the NCC of EPS are discussed.
