Software tool for verification of sampled values transmitted via IEC 61850-9-2 protocol

Nowadays is increasingly used process bus for communication of equipments in substations. In addition to signaling various statuses of device using GOOSE messages it is possible to transmit measured values, which can be used for diagnostic of system or other advanced functions. Transmission of such values via Ethernet is well defined in protocol IEC 61850-9-2. Paper introduces a tool designed for verification of sampled values generated by various devices using this protocol.
