IEC/TR 61850-90-5:2012(E) provides a way of exchanging synchrophasor data between PMUs, PDCs WAMPAC (Wide Area Monitoring, Protection, and Control), and between control center applications. The data, to the extent covered in IEEE C37.118-2005, are transported in a way that is compliant to the concepts of IEC 61850. However, given the primary scope and use cases, this document also provides routable profiles for IEC 61850-8-1 GOOSE and IEC 61850-9-2 SV packets. These routable packets can be utilized to transport general IEC 61850 data as well as synchrophasor data.

IEC TR 61850-90-4:2020(E), which is a Technical Report, is intended for an audience familiar with network communication and/or IEC 61850-based systems and particularly for substation protection and control equipment vendors, network equipment vendors and system integrators.
This document focuses on engineering a local area network limited to the requirements of IEC 61850-based substation automation. It outlines the advantages and disadvantages of different approaches to network topology, redundancy, clock synchronization, etc. so that the network designer can make educated decisions. In addition, this document outlines possible improvements to both substation automation and networking equipment.
This document addresses data transfer over the network in IEC 61850, such as transmitting tripping commands for protection via GOOSE messages, and in particular the multicast data transfer of large volumes of sampled values (SV) from merging units (MUs).
This document considers seamless redundancy to increase the network availability under failure conditions and the high precision clock synchronization that is central to the process bus and synchrophasor operation.
This document is not intended as a tutorial on networking or on IEC 61850. Rather, it references and summarizes standards and publications to assist the engineers. Many publications discuss the Ethernet technology but do not address the networks in terms of substation automation. Therefore, many technologies and options have been ignored, since they were not considered relevant for a future-proof substation automation network design.
This document does not address network-based security, which is the subject of IEC 62351 and IEC 62443.
This document does not address technologies for wide area networks; these are covered by IEC TR 61850-90-12. Guidelines for communication outside of the substation that uses exclusively the routable Internet Protocol have been published, especially in documents IEC TR 61850-90-1 (substation to substation), IEC TR 61850-90-2 (substation to control center) and IEC TR 61850-90-5 (synchrophasor transmission). However, data flows used in substation-to-substation communication, or substation-to-control centre communication such as R-GOOSE and R-SV are covered when they transit over Ethernet links within the substation.
This document does not dispense the responsible system integrator from an analysis of the actual application configuration, which is the base for a dependable system

IEC TR 61850-90-3:2016(E) addresses communication aspects related to specific sensor networks that are widely used as well as information exchange towards asset management systems. Since the outcome of this work will affect several parts of IEC 61850, in a first step, this technical report has been prepared to address the topic from an application specific viewpoint across all affected parts of IEC 61850. Once this technical report has been approved, the affected parts of the standard will be amended with the results from the report. This approach is similar to what is done as an example with IEC 61850-90-1 for the communication between substations.
The contents of the corrigendum of November 2020 have been included in this copy. -

Methodologies for IEC TR 61850-90-11:2020(E), which is a Technical Report, describes the methodologies for the modelling of logics for IEC 61850 based applications in power utility automation. In particular, it describes the functional view of logic based on existing logical nodes for generic process automation and the operational modes of the logic. Furthermore it includes the specification of the standard language to be applied to specific the logic as well as the related data exchange format between engineering tools and their application as well as the mapping of logic elements to IEC 61850 data types.
The examples or use cases given in this document are based on the class model introduced in IEC 61850-7-1 and defined in IEC 61850-7-3. The logical node and data names used in this document are defined in IEC 61850-7-4, the services applied in IEC 61850-7-2. The naming conventions of IEC 61850-7-2 are applied in this document also.
If extensions are needed in the application examples, the normative naming rules for multiple instances and private, compatible extensions of Logical Node (LN) Classes and Data Object Names defined in IEC 61850-7-1 are considered.
This document describes the use of IEC 61850 extensions for modelling logics, therefore it implies some tutorial material. However it is advisable to read IEC 61850-6 and IEC 61850-7-1 in conjunction with IEC 61850-7-3 and IEC 61850-7-2 first and IEC 61131-3 as reference for the programming language of logic.
The different logics included in any IED in an IEC 61850 based system can be classified into two groups:
• Fixed Logic: These logics are predefined mostly for critical and complex functions. They are typically included in the IED´s defined application, potentially implemented in software, firmware or hardware, and are not modifiable with IEC 61850 tools and services. These logics are implementation specific. Fixed logic is out of the scope of this document.
• Editable Logic: These are user configurable / programmable logics which shall be modelled through IEC 61850 configuration tools and be accessible by IEC 61850 services. These logics can be application specific.
The major goal of this document is to adopt the given functionality of an IED to fit to specific application function demands. This is to provide a definition of the methodology for describing and exchanging logics using an IEC 61850 compatible solution. As a benefit the same logic description will be valid and vendor-independent, so it could be used for different IEDs. It is up to the tools to understand this standard description in order to be able to manipulate the logics and to properly configure the IEDs.
Graphical representation of logic is currently out-of-scope of the IEC 61850 series, even if it is part of the PLCopen XML specification. The representation is subject to the engineering tools.
Modelling logics requires some extension of the currently defined data model and / or an extension of the content in the SCL files which is described and which needs to be considered in later editions of IEC 61850-6 and IEC 61850-7-4. of logics for IEC 61850 based applications -
