Communication networks and systems for power utility automation – Using IEC 61850 to transmit power quality data
| Published By | Publication Date | Number of Pages |
| BSI | 2017 | 96 |
This part of IEC 61850, which is a technical report, provides a way of exchanging power quality data between instruments whose functions include measuring, recording and possibly monitoring power quality phenomena in power supply systems, and clients using them in a way that is compliant to the concepts of IEC 61850.
The main goal is the interoperability of power quality instruments.
NOTE 1 The measurement of PQ phenomena maybe provided by communication e.g. IEC 61850-9-2 or instrument transformers. Their application is outside of the scope of this document.
NOTE 2 This document does not set any limits for power quality values, but only repeats limits from other sources (e.g. EN 50160, IEC TS 62749) as suitable examples.
NOTE 3 This document provides recommendations for naming conventions for PQ measurements provided by power quality instruments to manifest the usage of Power quality measurement methods and to ensure interoperability.
This document provides
-
Guidelines for using of IEC 61850 for power quality domain,
-
Name space extensions based on power quality function assessment,
-
Profile for using IEC 61850 in the specific context of IEC 61000-4-30.
Specific power quality requirements that cannot be wholly covered with existing Logical Nodes (LN) or Common Data Classes (CDC) (e.g. LN for continuous power quality recorders, LN for RVC, etc.) will be addressed and added in the next editions of IEC 61850-7-3 and IEC 61850-7-4.
NOTE 4 This document references to/is compliance with the future 61850 amendment 2.1, and also bring the needed elements which are mandatory to understand the document; at least the new presence conditions rules, as well as the enumeration models.
The namespace introduced by this document in Clause 7 has the following properties:
-
Namespace Version: 2016
-
Namespace Revision:
-
UML model file which reflects this namespace edition: wg10uml02v20draftPQ00- wg18uml02v11b-wg17uml02v17c-jwg25uml02v04c-tc17umlv0-tc38umlv0.eap, UML model version WG10UML02v20DraftUpdate
-
Namespace release date: 2017-01-17
-
Namespace name: “(Tr)IEC61850-90-17:2016”
This name space is considered as “transitional” since the models are expected to be included in future editions of IEC 61850-7-4xx. Potential extensions/modifications may happen if/when the models are moved to International Standard status. Only the new data objects and CDCs which are represented in bold-italic will be tagged with this namespace name. The others still refer to the namespace where they are primarily defined.
The Profile (set of additional rules) for using IEC 61850 in the specific context of IEC 61000-4-30, introduced in this document in Clause 6 is named “Profile_61000-4-30_(Tr)IEC61850-90-17:2016”.
