Web Services for Fault Analysis in Smart Grid Applications

Abstract This paper presents a novel approach for fault and disturbance analysis in electrical power systems. A new software framework for analysing faults and disturbances in smart grid applications based on web services technology is proposed. The fault analysis system is designed to comply with the IEC 61850 standard, which is a core enabling technology for the smart grid. The data for analyses are obtained via a substation local area network from intelligent electronic devices complying with IEC 61850 on ethernet. Demonstrations of the following services currently implemented in the web services are presented: signal segmentation, signal modelling, fault type classification and fault location service. Such services are designed to enhance manual investigations performed by engineers.
