This part of IEC 61968 specifies profiles that can be used to exchange Network Models in a
Utility or between a Utility and external applications to the utility. This document provides a list
of profiles which allow to model balanced and unbalanced distribution networks in order to
conduct network analysis (Power flow calculation). Therefore, it leverages already existing
profiles (IEC 61970-45x based on IEC 61970-301 (CIM base) or profiles based on
IEC 6196811
CIM extension for Distribution). This document reuses some profiles without any
change, or eventually extends them or restricts them. Moreover, it proposes other profiles to
reflect Distribution needs.
Use of CIM in Distribution is not a new topic. Several documents can be of interest
[13][17][18][19][20]. This document includes informative parts, as CIM model extensions, which
could be integrated in future versions of the IEC CIM Model. These extensions have been used
by some utilities for utility internal information exchange use cases and to support information
exchanges between different market participants like Transmisstion System Operators (TSO),
Distributed System Operators (DSO), Distributed Network Operators (DNO) and Significant Grid
Users (SGU) including generators and industry (see Annex J for example).

IEC 61000-6-3:2020 is a generic EMC emission standard applicable only if no relevant dedicated product or product family EMC emission standard has been published. This part of IEC 61000 for emission requirements applies to electrical and electronic equipment intended for use at residential (see 3.1.14) locations. This part of IEC 61000 also applies to electrical and electronic equipment intended for use at other locations that do not fall within the scope of IEC 61000-6-8 or IEC 61000-6-4. The intention is that all equipment used in the residential, commercial and light-industrial environments are covered by IEC 61000-6-3 or IEC 61000-6-8. If there is any doubt the requirements in IEC 61000-6-3 apply. The conducted and radiated emission requirements in the frequency range up to 400 GHz are considered essential and have been selected to provide an adequate level of protection of radio reception in the defined electromagnetic environment. Not all disturbance phenomena have been included for testing purposes but only those considered relevant for the equipment intended to operate within the locations included within this document. The emission requirements in this document are not intended to be applicable to the intentional transmissions and their harmonics from a radio transmitter as defined by the ITU. This third edition cancels and replaces the second edition published in 2006 and its Amendment 1:2010. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) alternative method for measuring conducted emissions on DC ports;
b) limits and requirements applicable only to equipment intended to be used in residential locations;
c) more stringent limits for DC power ports.
NOTE 1 Safety considerations are not covered by this document.
NOTE 2 In special cases, situations will arise where the levels specified in this document will not offer adequate protection; for example where a sensitive receiver is used in close proximity to an equipment. In these instances, special mitigation measures can be employed. NOTE 3 Disturbances generated in fault conditions of equipment are not covered by this document.
NOTE 4 As the requirements in this document are more stringent or equivalent to those requirements in IEC 61000-6-4 and IEC 61000-6-8, equipment fulfilling the requirements of this document comply with the requirements of IEC 61000-6-4 and IEC 61000-6-8.

This part of IEC 61000 is applicable to the immunity requirements of electrical and electronic
equipment to radiated electromagnetic energy. It establishes test levels and the required test
procedures.
The object of this document is to establish a common reference for evaluating the immunity of
electrical and electronic equipment when subjected to radiated, radio-frequency
electromagnetic fields. The test method documented in this part of IEC 61000 describes a
consistent method to assess the immunity of an equipment or system against RF
electromagnetic fields from RF sources not in close proximity to the EUT. The test environment
is specified in Clause 6.
NOTE 1 As described in IEC Guide 107, this is a basic EMC publication for use by product committees of the IEC.
As also stated in Guide 107, the IEC product committees are responsible for determining whether this immunity test
standard should be applied or not, and if applied, they are responsible for determining the appropriate test levels
and performance criteria. TC 77 and its sub-committees are prepared to co-operate with product committees in the
evaluation of the value of particular immunity tests for their products.
NOTE 2 Immunity testing against RF sources in close proximity to the EUT is defined in IEC 61000-4-39.
Particular considerations are devoted to the protection against radio-frequency emissions from
digital radiotelephones and other RF emitting devices.
NOTE 3 Test methods are defined in this part for evaluating the effect that electromagnetic radiation has on the
equipment concerned. The simulation and measurement of electromagnetic radiation is not adequately exact for
quantitative determination of effects. The test methods defined in this basic document have the primary objective of
establishing an adequate reproducibility of testing configuration and repeatability of test results at various test
facilities.
This document is an independent test method. It is not possible to use other test methods as
substitutes for claiming compliance with this document.

This part of IEC 62541 defines the OPC Unified Architecture (OPC UA) Services. The
Services defined are the collection of abstract Remote Procedure Calls (RPC) that are
implemented by OPC UA Servers and called by OPC UA Clients. All interactions between
OPC UA Clients and Servers occur via these Services. The defined Services are considered
abstract because no particular RPC mechanism for implementation is defined in this
document. IEC 62541‑6 specifies one or more concrete mappings supported for
implementation. For example, one mapping in IEC 62541‑6 is to XML Web Services. In that
case the Services described in this document appear as the Web service methods in the
WSDL contract.
Not all OPC UA Servers will need to implement all of the defined Services. IEC 62541‑7
defines the Profiles that dictate which Services need to be implemented in order to be
compliant with a particular Profile.

This part of IEC 62541 defines the OPC Unified Architecture (OPC UA) Profiles. The Profiles
in this document are used to segregate features with regard to testing of OPC UA products
and the nature of the testing (tool based or lab based). This includes the testing performed by
the OPC Foundation provided OPC UA CTT (a self-test tool) and by the OPC Foundation
provided Independent certification test labs. This could equally as well refer to test tools
provided by another organization or a test lab provided by another organization. What is
important is the concept of automated tool-based testing versus lab-based testing. The scope
of this standard includes defining functionality that can only be tested in a lab and defining the
grouping of functionality that is to be used when testing OPC UA products either in a lab or
using automated tools. The definition of actual TestCases is not within the scope of this
document, but the general categories of TestCases are within the scope of this document.
Most OPC UA applications will conform to several, but not all, of the Profiles.

The common information model (CIM) is an abstract model that represents all the major objects
in an electric utility enterprise typically involved in utility operations. By providing a standard
way of representing power system resources as object classes and attributes, along with their
relationships, the CIM facilitates the integration and interoperability of network applications
developed independently by different vendors, between entire systems running network
applications developed independently, or between a system running network applications and
other systems concerned with different aspects of power system operations, such as generation
or distribution management. SCADA is modelled to the extent necessary to support power
system simulation and inter-control centre communication. The CIM facilitates integration by
defining a common language (i.e. semantics) based on the CIM to enable these applications or
systems to access public data and exchange information independent of how such information
is represented internally.
The object classes represented in the CIM are abstract in nature and can be used in a wide
variety of applications. The use of the CIM goes far beyond its application in an EMS. This
document should be understood as a tool to enable integration in any domain where a common
power system model is needed to facilitate interoperability and plug compatibility between
applications and systems independent of any particular implementation.
Due to the size of the complete CIM, the object classes contained in the CIM are grouped into
several logical Packages, each of which represents a certain part of the overall power system
being modelled. Collections of these Packages are progressed as separate International
Standards. This document specifies a Base set of packages which provide a logical view of the
functional aspects of Energy Management System (EMS) and power system modelling
information within the electric utility enterprise that is shared between all applications. Other
standards specify more specific parts of the model that are needed by only certain applications.
Subclause 4.3 of this document provides the current grouping of packages into standards
documents.

This part of IEC 61850 specifies a method of exchanging data through any kinds of network, including public networks. Among the various kinds of services specified in IEC 61850-7-2, only the client/server and time synchronization services are considered so far.
NOTE Client/server services of GOOSE and SMV models are mapped as well (see Table 1). For the client/server services, the principle is to map the objects and services of the ACSI (Abstract Communication Service Interface defined in IEC 61850-7-2) to XML messages transported over XMPP. The mapping description includes mainly three aspects:
• The usage of the XMPP protocol itself, describing in details which features are really used and how they are used by the mapping (see Clause 6).
• How to achieve end-to-end secured communications (see Clause 7).
• The description of the XML payloads corresponding to each ACSI service thanks in particular to the XML Schema and XML message examples (starting at Clause 9).
NOTE 1 This document does not address the detailed usage of the XMPP protocol.
NOTE 2 This document does not address system management services.
NOTE 3 For the information of people familiar with the mapping defined in IEC 61850-8-1, the XML messages defined in the present document are derived from those defined in IEC 61850-8-1 but with an XML encoding instead of a binary one. In this way implementing gateways between IEC 61850-8-1 and IEC 61850-8-2 is very straightforward in both directions. However reading IEC 61850-8-1 is not necessary to understand the present document except when it is used in conjunction with one of the GOOSE mappings described in IEC 61850-8-1.

applies to electrical and electronic apparatus intended for use in industrial environments, as described below. Immunity requirements in the frequency range 0 Hz to 400 GHz are covered. No tests need to be performed at frequencies where no requirements are specified. This generic EMC immunity standard is applicable if no relevant dedicated product or product-family EMC immunity standard exists. This standard applies to apparatus intended to be connected to a power network supplied from a high or medium voltage transformer dedicated to the supply of an installation feeding manufacturing or similar plant, and intended to operate in or in proximity to industrial locations, as described below. This standard applies also to apparatus which is battery operated and intended to be used in industrial locations. The environments encompassed by this standard are industrial, both indoor and outdoor. The immunity requirements have been selected to ensure an adequate level of immunity for apparatus at industrial locations. The levels do not, however, cover extreme cases, which may occur at any location, but with an extremely low probability of occurrence. Not all disturbance phenomena have been included for testing purposes in this standard, but only those considered as relevant for the equipment covered by this standard. These test requirements represent essential electromagnetic compatibility immunity requirements.
