Figure 4-2: EnerVista SR3 GOOSE Transmission page
• GOOSE ID: A string of up to 40 characters that represent the IEC 61850 GOOSE
application ID (GoID). This string identifies the GOOSE Tx message to the receiving
device.
• VLAN Identifier/Priority: a two-byte value whose 3 most significant bits define the
user priority and the twelve least significant bits are for the VLAN identifier. I.e. 32768.
• ETYPE AppID ): to select ISO/IEC 8802-3 frames containing GSE Management and
GOOSE messages and to distinguish the application association.
• Update Time: time to delay transmission of the next iteration of a particular GOOSE
message if no value within the message has changed. I.e. 60. Measured in ms.
• Conf Revision Number: This number updates automatically after Tx data set has been
modified and the relay power has been cycled.
• Destination MAC Address: This setting is required to ensuring interoperability as some
vendors require valid range of destination MAC addresses in GOOSE messages.
• Quality Flags: In order to ensure interoperability with some vendors, it has been
added a quality flag associated to a data item. The quality flags item only can be set if
its associated data item is selected. The data type of the quality flags is Bitstring13
and the attribute will always set to value "0" at the protocol level.
All the elements in a dataset can be mapped by the user to any available digital value
within the 350 relay, including:
• Alarm elements
• Protection elements (Pickup, Dropout and Operate of all available protection elements)
