Information Systems of Relay Protection for Power System Analyzing

The paper describes information systems of relay protection for analyzing disturbances in transmission systems, their upgrade by Internet technologies, and the systems in the immediate future according IEC 61850. The data for analysis are obtained from the relay protection intelligent devices, disturbances recorders and SCADA system in automated high voltage (HV) substations. The information systems are used for analysis of voltage and current circumstances during disturbances in the network.
