Implementation requirements for automated fault data analytics in power systems

This paper addresses implementation requirements for a fully automated substation data integration and fault analysis for power system transmission lines. The approach is based on measurements from substation intelligent electronic device recordings. The proposed architecture provides a transparent approach to substation data management, analytics functions, as well as the visualization of the integrated data and analytics results. When combined with an efficient communication and data collection scheme, the solution bridges the gap between traditionally separated non-operational and operational data. The fault analytics results, traditionally obtained through off-line manual process, can now be used in an automated way to support on-line decisions when operating or restoring the power system. The solution is open for further expansions and interfacing to third-party systems. The paper illustrates implementation examples and provides initial in-house and field test results.
