CHAPTER 5: SETTINGS
5.3.4.12 IEC 61850 protocol
The C30 is provided with optional IEC 61850 communications. This feature is specified as a software option at
the time of ordering. See the Order Codes section in chapter 2 for details.
The IEC 61850 settings are accessible in EnerVista software or a substation configuration language (SCL) generating tool.
The path is Settings > Product Setup > Communications > IEC 61850 or Settings > IEC 61850. The settings are not
accessible from the front panel of the device.
IEC 61850 messaging can form part of protection schemes. Consider IEC 61850 settings with the same criticality as
protection element settings. To ensure reliable performance of protection schemes utilizing IEC 61850 messaging,
route IEC 61850 traffic on a separate port from SCADA communications, or use redundant, independent ports, and
a high-speed network recovery method, such as PRP.
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.
EnerVista setup for IEC 61850
The EnerVista UR Setup software provides the interface to configure C30 settings for the IEC 61850 protocol. This section
describes this interface. The software also supports import/export and merging of IEC 61850 Substation Configuration
Language (SCL) files as documented in the UR Family Communications Guide.
The IEC 61850 protocol configuration settings cannot be accessed through the UR front panel and are instead accessible
with the EnerVista software, via MMS query, read, and write services, or via 61850 SCL file transfer. Accordingly, whereas
other settings are presented in this manual as they appear on the front panel, IEC 61850 settings are presented as they
appear in the software. See the UR Family Communications Guide for MMS and SCL access. Note that if you update the IEC
61850 settings in the EnerVista software by writing to them by MMS while the corresponding IEC 61850 panel is open in
EnerVista, you need to close then open the panel in EnerVista for the correct readings to display.
IEC 61850 protocol configuration settings are accessed through software panels that are selected either in the Online
Window area (see figure) or the Offline Window area in the EnerVista software.
The EnerVista software also includes an interface that is compatible with firmware versions 5.0 to 7.2 to configure
subscribers. Use the Simplified GOOSE Configurator in the Offline Window area.
