Read One of the Best Papers on IEC 61850 ever Published

Eric A. Udren (a friend of mine) from Quanta Technology, LLC of Raleigh, North Carolina has written one of the best papers on the application of IEC 61850 in general and in the USA I ever read:

What Drives the Business Case for IEC 61850?
published in the December 2016 issue of the PAC World magazine.
This paper summarizes the experience of more than 10 years with the application of the standard series IEC 61850. It is a very easy to read and understand summary of the content of my training courses. After more than 230 training courses I conducted globally since 2003 and more than 4,200 experts educated in these courses I fully agree with the crucial recommendations of the paper:
Eric states at the very beginning (3rd sentence!): " ... one must first understand that IEC 61850 is not just a communications protocol." Well said. He lists many crucial facets.
The main part of Eric's conclusion is [highlights are added by myself]:
"The following action items can help the utility to achieve technical success and lowest life cycle costs:
  • Develop requirements for and relationships with product vendors, who must commit to support interoperable and sustainable products and designs over the service life of the PAC design.
  • Apply the sustainable design principles of the previous sections. If some of these seem unfamiliar, get expert help from vendors and from vendor-independent industry experts with experience in PAC system design and integration.
  • Create strong, rigid design standards; develop broadly useable documentation for new PAC design features like network configuration, data flows, and GOOSE messaging connections of functional points.
  • Set up rigid documentation and configuration management systems. With IEC 61850, much of the PAC design is no longer evident in the physical installation – this managed design information is the only tool to maintain the system.
  • Create a development laboratory to validate the performance of the design. Keep the laboratory throughout the installation life to train personnel, to troubleshoot bugs that arise in the field, and to test new product or firmware insertions in the existing design before authorizing those for field use.
  • Develop and run training programs for field maintenance personnel, including hands-on participation and feedback during the design and laboratory test phases.
  • Develop and run training programs for other enterprise stakeholders, including system planning, capital planning, purchasing, and operations teams.
  • After the pilot or trial phase, plan a crisp organizational transition to the new design at the fastest sustainable rate."

There have been a lot of misleading and strange statements on the benefits of IEC 61850 communicated ... trust the real experts like Eric Udren ...

One of the real show-stoppers of a beneficial application is the lack of education of many engineers. We offer the right experience and knowledge for your people to harvest the benefits of the application of IEC 61850 and other standards:

Animal "Attacks" on Power Systems - Worry About Squirrels

BBC news has published an interesting report on "Squirrel 'threat' to critical infrastructure".

According to the report "The real threat to global critical infrastructure is not enemy states or organisations but squirrels, according to one security expert.
Cris Thomas has been tracking power cuts caused by animals since 2013.
Squirrels, birds, rats and snakes have been responsible for more than 1,700 power cuts affecting nearly 5 million people, he told a security conference."

Are You Looking for Authenticated Encrypted Time Signals?

GPS-based time signals could be less robust and reliable - this has been discussed in various forums. Electric power systems rely on time synchronization you can trust.

In a new US DOE project (TASQC - Timing Authentication Secured by Quantum Correlations) experts are planning to develop authenticated encrypted time signals that mitigate known vulnerabilities in GPS-based time. The project aims to:
  • Develop and demonstrate a secure time distribution system using quantum-correlated signals over geographically wide area;
  • Develop and demonstrate protocols for time-stamp authentication for data reported from power systems;
  • Expand capability of the developed infrastructure for secure authentication of broadcast messages;
  • Evaluate the system for cyber- and physical-vulnerabilities;
  • Partner with industry to develop timing requirements for power systems and to refine design of system and protocols.
Phil Evans, Ph.D., TASQC Principle Investigator, Oak Ridge National Laboratory, respectfully requests your assistance for the TASQC project by both answering the questions in a brief survey, and distributing it amongst your colleagues in the electric power industry.

DTR IEC 61850-7-500: How to use IEC 61850 for SAS

IEC TC 57 has published a Draft Technical Report (57/1817/DTR; 84 pages) with guidelines on how to apply IEC 61850 for substation automation:

Communication networks and systems for power utility automation –
Part 7-500: Basic information and communication structure – Use of logical nodes for modeling application functions and related concepts and guidelines for substations

Voting closes 2017-02-17

This is a document that you MUST read when you are involved in substation automation.

This Technical Report of IEC 61850 describes the use of the information model for devices and functions of IEC 61850 in applications in substation automation systems but it may be used as informative input also for the modeling of any other application domain. In particular, it describes the use of compatible logical node names and data objects names for communication between Intelligent Electronic Devices (IED) for use cases. This includes the relationship between Logical Nodes and Data Objects for the given use cases. ...
Part 7-5 describes in examples the use of logical nodes for modeling application functions and related concepts and guidelines in general independently from any application domain respectively valid for all application domains in the electric power system (substation automation, distributed energy resources, hydro power, wind power, etc.). This part 7-500 describes in examples the use of logical nodes for application functions in substation automation including also line protection between substations. It implies also some tutorial material where helpful. But it is recommended to read parts IEC 61850-5 and IEC 61850-7-1 in conjunction with IEC 61850-7-3 and IEC 61850-7-2 first.

New: Modelling of Logics for IEC 61850 Based Applications

IEC TC 57 has published a very interesting proposal (57/1814/DC; 49 pages) for modelling logics:

IEC TR 61850-90-11, Communication networks and systems for power utility automation –
Part 90-11: Methodologies for modelling of logics for IEC 61850 based applications

Comments are expected by 2017-02-03

This part of IEC 61850 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 IEC 61131-3 PLC programming language is used to describe syntax of functions.

Example PLD (Programmable Logic Description): The PLD file contains the logic unit program code in PLC OpenXML format, representing the description of the logic programmable scheme that can then be mapped to a GAPC LN instance. Excerpt:



... more to come next year.

Guideline for definition of Basic Application Profiles (BAPs) using IEC 61850

IEC TC 57 has published a document for comments (57/1813/DC, 27 pages) on application profiles::

Draft IEC TR 61850-7-6, Communication networks and systems for power utility automation –
Part 7-6: Guideline for definition of Basic Application Profiles (BAPs) using IEC 61850

Comments are expected by 2017-02-03

This guideline is focused on building Application / function profiles and specifies a methodology to define Basic Application profiles (BAPs). These Basic Application profiles shall provide a framework for interoperable interaction within or between typical substation automation functions. BAPs are intended to define a subset of mandatory features of IEC 61850 in order to increase interoperability in practical applications.

In the context of standards the term “profile” is commonly used to describe a subset of an entity (e.g. standard, model, rules).
Accordingly an IEC 61850 standard profile contain a selection of data models (mandatory elements), communication services applicable and relevant engineering conventions (based on the Substation Configuration Language SCL defined in IEC 61850-6) for an application function of a specific use case in the domain of power utility automation.
Depending on the scope and objective different profile types can be distinguished:

  • User profile – defined subset that is valid for a specific user / organization (e.g. utility)
  • Product / Device profile – implemented subset in a specific vendor product /device
  • Domain profile – defined subset for a specific domain and relevant use cases (e.g. monitoring of substation)
  • Application / function profile
A nice example is contained in Annex A:
Example for BAP of distributed automation function “reverse blocking” using BAP template

CIM for Distribution Network Operations

IEC TC 57 has published the FDIS (57/1810/FDIS; 160 pages) of the future standard IEC 61968-3 Ed2:
Application integration at electric utilities - System interfaces for distribution management -
Part 3: Interface for network operations
Voting closes 2017-02-03

IEC 61968 provides utilities the means to supervise main substation topology (breaker
and switch state) and control equipment status. It also provides the means for handling
network connectivity and loading conditions. Finally, it makes it possible for utilities to locate
customer telephone complaints and supervise the location of field crews.
IEC 61968-3 specifies the information content of a set of message payloads that can be used
to support many of the business functions related to network operations. Typical uses of the
message payloads defined in IEC 61968-3 include data acquisition by external systems, fault
isolation, fault restoration, trouble management, maintenance of plant, and the commissioning
of plant.

This part is closely related to the Common Information Model (CIM).

OpenGridMap - Help to collect data and produce power grid approximations for CIM


OpenGridMap is a new open community that crowdsources realistic power grid data to be used for research purposes. Here you will find the tools for crowdsourcing power grid data. The goal is to create an open platform for inferring realistic power grids based on actual data. Our vision is to provide a tool to researchers and practitioners that is able to produce realistic input data for simulation studies. OpenGridMap will support the entire process from data collection to formatting grid data for various purposes. We explore innovative ways to capture data and produce power grid approximations, e.g., using smartphone apps, drones, expert classification, existing map APIs, and graph inference algorithms.

Click HERE to visit the OpenGridMap website.

The next step would be to convert the collected data into a CIM and SCL format ... it is underway for CIM (Common Information Model):

OpenGridMap: towards automatic power grid simulation model generation from crowdsourced data
By Jose Rivera, Technische Universität München

"OpenGridMap is an open source project that crowdsources realistic power grid data to be used for research purposes. In this paper, we propose an approach for the automatic generation of power gird simulation models from crowdsourced data. The proposed approach orders the crowdsourced data into a power circuit relation which is then used to produce a CIM description file and subsequently a power grid simulation model. ..." ... and I guess the modelling in IEC 61850-6 SCL (System Configuration Language) will follow soon - I am sure.

Draft IEC 62351-90-2 Deep Packet Inspection (DPI) of encrypted communications

IEC TC 57 just published a very crucial draft document proposing a new topic to the security of communication in power delivery systems applicable to DNP3, IEC 60870-5-104, IEC 60870-6 (TASE.2), IEC 61850 and the like:
57/1792/DC
Proposed draft for IEC TR 62351-90-2, Power systems management and associated information exchange – Data and communications security –
Part 90-2 Deep Packet Inspection (DPI) of encrypted communications

The standard series IEC 62351 comprises methods to secure communication channels between IEDs and between IEDs and SCADA systems. Complex communication networks have to be monitored and health-checked properly, both from an operational and from a security perspective.
The monitoring process used is called Deep Packet Inspection (DPI), and relies on the availability of the whole payload for inspection. The need for DPI on communication channels between IEDs and SCADA and/or between IEDs by an independent third party is really important.
This report serves as a guide for the implementation of DPI in encrypted communications. It is intended as an overview of existing and possible new solutions for DPI, analyzing the impact on several factors, including security, performance and cost.
