GOOSE is used in substation automation for fast horizontal communication between protection relays. GOOSE can be used for direct data exchange, for example, of interlocking and blocking information between the protection relays. According to the IEC 61850-8-1 standard, GOOSE uses a publisher/subscriber profile in which information is shared from one device to one or several devices by using Ethernet multicast messages. A message is an image of a sent IEC 61850 data set that is defined in the configuration.
PCM600 or any other communication configuration tool can be used to configure the vertical and horizontal communication properties of the protection relays.
The protection relay can send any type of status or measurement data in the GOOSE messages from its IEC 61850 data model.
When the protection relay is configured to send measurements, the analog, integer or counter type data should be placed in its own data set to minimize the bandwidth consumption in the network and to avoid unnecessary publishing of unchanged status data. The triggering of analog data sending is controlled by deadband handling, zero-point clamping and limit supervision.
The horizontal communication configuration consists of the protection relays' GOOSE control block, data set and GOOSE input configuration. The result of the configuration work is a system configuration which is used for the protection relays. The used files in the workflow are IEC 61850 standard format SCL files.
