Initial Setting Group
Range: 1 to 6 in steps of 1
Default: 1
The entered value sets the initial value of the non-volatile register normally controlled by the service SelectActiveSG. This
initialization occurs only on the UR reboot immediately following the receipt of a valid CID file.
This setting is not mapped into the IEC 61850 information model, but sets the value of SettingControl element attribute
actSG in SCL files.
Overview
IEC 61850 is a series of international standards and technical reports applicable to power utility automation systems. It
includes semantics, abstract communication services, specific communication services, performance specifications,
network engineering guidelines, configuration description methodologies, and engineering processes. The standard
enables interoperability among intelligent electronic devices (IEDs) from different suppliers and interoperability among
software configuration tools from different suppliers. Interoperability in this case is the ability for IEDs to operate on the
same network or communication path sharing information and commands, and for configuration tools to understand
each other's configuration files.
The UR family supports a large subset of IEC 61850 features. These are detailed in the UR Family Communications Guide
and include the information model, GOOSE publish, GOOSE subscribe, buffered report server, unbuffered report server, and
Manufacturing Message Specification (MMS) query, read, write, and control services. In addition, the URs and their
EnerVista UR Setup software support IEC 61850 Substation Configuration Language (SCL) file import/export and merging.
Whereas prior UR releases used edition 1.0 of IEC 61850, this release uses edition 2.0, with certain modifications according
to IEC/TR 61850-90-5. Only edition 2.0 61850 configuration tools can interoperate with edition 2.0 devices, such as the UR
7.3x release. This UR release uses edition 2.0 SCL, which differs from edition 1.0 SCL. GSSE, fixed GOOSE, and fixed report
services of previous releases are no longer supported, and thus UR devices of previous releases using these features have
to be converted to configurable GOOSE to communicate with a 7.3x or later device.
Many settings of UR protection, control, and monitoring elements, that is to say elements that are not concerned with the
IEC 61850 protocol, can nevertheless be accessed via IEC 61850. These settings are documented elsewhere in this Settings
chapter. This section of the Settings chapter deals solely with the settings that configure the IEC 61850 protocol itself.
The maximum number of simultaneous clients supported by the UR family is five.
