Web Services for Automated Fault Analysis in Electrical Power Systems

Web Services for Automated Fault Analysis (WS-AFA) in Electrical Power System are described in this paper. WS-AFA is a new Information Technology solution for automated investigation and analysis of fault and disturbance records obtained from Digital Fault Recorders (DFRs) or other Intelligent Electronic Devices (IEDs) in substations. The paper describes the overall system architecture as well as the implementation of the services. C # and Dot NET technology has been successfully used for efficient implementation of the web services. WS-AFA is composed of signal segmentation, signal analysis, fault type classification, COMTRADE viewer and fault location services. Such services are designed to enhance manual investigation performed by engineers in power utilities
