GOOSE CONFIGURATION VIA THE 3 SERIES MENUS

GOOSE Rx

4-6
• 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 ensure interoperability as some
vendors require valid range of destination MAC addresses in GOOSE messages.
• Quality Flags: In order to ensure interoperability with some vendors, there is a quality
flag associated with 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 3 Series relay, including:
• Alarm elements
• Protection elements (Pickup, Dropout and Operate of all available protection elements)
• Control element (all available control elements)
• Status of digital inputs
• Status of digital outputs
• Status of virtual inputs
• Status of virtual outputs.
The destination multicast address for GOOSE messages is composed of the MAC address of
the device, with the least significant bit in the most significant byte, set to 1.
The 3 Series relay relay does not generate ICD files that describe the format of transmitted
GOOSE items. EnerVista 3 Series Setup software is used to generate these files, and the
files must contain at least the following information:
• Mandatory Nodes: LLN0, LPHD, GGIO, etc.
• GOOSE Configuration: Control Block, Dataset, etc.
• Dataset configuration.
Once a GOOSE message is transmitted, it will be retransmitted at an increasing time
interval as follows: 4ms, 8ms, 16ms, and then 1 second.
The 3 Series relay firmware allows the user to configure up to 8 separate GOOSE
messages for reception. One GOOSE message consists of 2 parts: Header and Dataset. The
Header is used for identification and the Dataset for data handling.
At this point , it is convenient to clarify the difference between Remote GOOSE and Remote
Device. One Remote Device can send more than one GOOSE, so from the reception point of
view, it is not very useful to handle Remote Devices. Instead, it is simpler to deal with
Remote GOOSE messages.
The 3 Series relay firmware is able to receive up to a total of 8 remote GOOSE messages
transmitted from up to a maximum of 8 remote devices.
