Draft TR IEC 61850-7-6 published: Guideline for definition of Basic Application Profiles (BAPs) using IEC 61850

IEC TC 57 just published the 68 page draft Technical Report IEC 61850-7-6:

57/1986/DTR

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

Voting closes 2018-06-08.

"The IEC 61850 standard series offers a broad basis for communication networks and systems in power utility automation. Due to its broad coverage of power utility automation applications, it is up to the standard’s user (utility, vendor, system integrator…) to pick and choose specific options from the standard in order to meet the requirements of the intended objective. As a consequence, implementations of IEC 61850 represent specific subsets of the standard.
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 - subset covering a specific application or function (e.g. substation interlocking)

These profile types target on reducing complexity and facilitate interoperability for their specific scope and during engineering and device / substation lifetime. In order to achieve both these goals - a properly defined profile and appropriate implementations (processes, tools, products) that support the profile are required."

Note that IEC 61850 is not that complex - but it is very comprehensive!!
Comprehensiveness with regard to:

  1. Number of parts: some 50 inclusing drafts
  2. Number of Logical Nodes
  3. Number of Data Objects
  4. Configuration language
  5. Number of task forces working on new stuff
  6. Number of applications that can be covered
  7. ...

The most crucial challenge is this: How can I find what may be of interest for my application? I hope somebody will do a good job in preparing an overview of models published and under preparation.
Let me know if you are aware of some good document or website ...

Configuration Description Language for Extensions for Human Machine Interfaces

IEC TC 57 just published a very interesting committee draft for machine support of automatic mapping the SCL models to HMIs:

IEC 61850 (57/1984/CD):
Communication networks and systems for power utility automation –
Part 6-2: Configuration description language for extensions for human machine interfaces

Closing date for comments: 2018-06-01 

"This International Standard describes how the graphical components and their interactions
found within HMI applications are to be described using the Graphical Configuration
Language (GCL) and the HMI Configuration Language (HCL). It will describe how the
graphical elements – described in GCL – are to be bounded to the IEC 61850 elements
defined by IEC 61850’s System Configuration Language (SCL). ..."

The following excerpt from the CD gives an impression on how the HMI configuration is intended to be automatically derived (supported) by a new graphical configuration namespace:



Wow, this is really a major step forward!

New Merging Unit Development Kit

A new Merging Unit Development Kit based on the NovTech IoT Smart Grid Platform with Intel Cyclone V SoC Core is available for your next project.
Utility companies are adapting their infrastructures to support bidirectional energy flow to handle the emergence of DER (Distributed Energy Resources) via microgrids, photovoltaic panels, and local energy storage. As distributed energy generation increases, new intelligence of sensors, measurement and protection equipment will be required to process data at the edge. Also with the increase in variable DER, it is more challenging for substations to deliver sinusoidal and predictable steady-state voltage and current. Utility companies rely on substation metering of secondary voltage (VT) and current transformer (CT) circuits to detect performance issues and to provide vital information in real time to distributed digital protection nodes.

To satisfy this need, SystemCORP and Intel developed an IEC 61850-9-2LE compliant merging unit solution in form of a demonstrator/development platform.

This development kit consists of 6 parts:

  1. NovTech IoT Octopus Smart Grid IoT Platform
  2. SystemCORP VT/CT Interface board
  3. SystemCORP IEC 61850-9-2LE Sample Value software stack (PIS-11) on ARM Cortex A9 core 1
  4. SystemCORP IEC standard 61850 server/client software stack (PIS-10) on ARM Cortex A9 core 2 (optional)
  5. Flexibilis embedded FPGA analogue front-end IP core
  6. Flexibilis Ethernet PRP/HSR FPGA IP core (optional)

How many employees will drive an electric vehicle?

A German manager recently said that 500 employees of his company drive by car to the company every workday. He expects that in the future 250 will use electric cars and will charge their cars within the first hour after they arrived. The company would need 10 times more power than today!
Ok! Hm!?
What do you think about these assumptions? 250 EVs charging in the first hour!?
As an engineer I am wondering that experts come up with such examples. First of all, I do not expect that 50 per cent of the car owners will buy an electric car in the next years. Even if they would do, why do 250 car drivers want to charge at the companies car park in the morning when they arrive?
He concludes that "we engineers have not yet thought through to the end".
I guess a lot of engineers have thought through to the end - but not many engineers or politicians are listening!

Click HERE for the report "Netzstabilität braucht Digitalisierung und Automatisierung" in the vdi nachrichten (German).

These discussions remind me of the situation in the early 80s when we had the discussion on CSMA/CD (Ethernet, IEEE 802.3) versus Token Passing (IEEE 802.4). Under the assumption that we have a shower of messages to be sent by all attached devices at the same time, we found that Ethernet could not efficiently manage the communication due to many collisions. Token Passing was understood to manage such a situation very well. Ok.
Another assumption, high load from one device only, could easily be managed by CSMA/CD - but Token Passing would end up in very low throughput ... many other assumptions could be made.
So, what is the realistic assumption for communication? Nobody knows - it all depends.
Finally Switched Ethernet (a major new development) solved the collision problem ... and Token Passing more or less became obsolete in the automation world.

In the energy domain we need first to find the future new mix of power generation and how to store, transmit, distribute, and use the power - then we can think about automation and communication. The most crucial issue may be: Who is paying for all the changes?

By the way: We (many engineers) know how to communicate: IEC 61850 is one of the most crucial solution ... and how (not yet what) to automate.

First Amendment of IEC 61850-4: System and Project Management

IEC TC 57 just published the IEC 61850-4 Amendment 1 (57/1922/CDV)
– Communication networks and systems for power utility automation
Part 4: System and project management

The main extensions of the edition 2 are:
  1. New sub-chapter 5.3.6 describes the engineering tool workflow and its chronology (which SCL files are exchanged in between configuration tools) through 3 use cases: the classical use case, the change of system tool and the interaction between 2 projects.
  2. New sub-chapter 6.4 talks about backward compatibility and deals with replacement or extension whatever the component is provided by the same or different manufacturer. To do so, it scrutinizes through 4 use cases, what kind of impacts could be acceptable for IED or tools.
The ballot closes 2018-02-02.
The CDV (committee draft for vote) is accessible for PUBLIC comments by every interested person.

Note that the amendment has already been blended into the edition 2 document for easier reading: 57/1923/INF

These extensions answer a couple of questions that come up during every seminar and in many discussions. They are extending the explanations of SCL (part 6).
The document is worth to study.

What happens during a blackout - Comprehensive Report of the German Parliament's study

The OFFICE OF TECHNOLOGY ASSESSMENT AT THE GERMAN BUNDESTAG
published in 20111 a very comprehensive report:

What happens during a blackout - 
Consequences of a prolonged and wide-ranging power outage

"THE COMMITTEE’ S PREFACE
Infrastructures such as a reliable energy supply, functioning water-supply and wastewater-disposal systems, efficient modes of transport and transport routes and also information technology and telecommunications technology that can be accessed at all times represent the lifeblood of high-technology industrialised nations. The Committee on Education, Research and Technology Assessment therefore commissioned the Office of Technology Assessment at the German Bundestag (TAB) to investigate the possible effects of a prolonged and widespread power blackout on highly critical infrastructures such as drinking water, wastewater, information and communications systems, financial services and health services, especially against a backdrop where the blackout has a cascading effect spanning state and national boundaries.
In Germany, several recent natural disasters and technical malfunctions (Elbe and Oder floods in 2002/2005, power blackout in the Münsterland in 2005, the Kyrill storm in 2007) have highlighted the population’s dependence on such (critical) infrastructures. Supply bottlenecks, public safety problems and disruptions to road and rail transport have revealed the vulnerability of modern societies and made extreme demands on health, emergency and rescue services...."

Click HERE for the 250 page report [English].
Click HERE for the German version.

The report is one of the best descriptions I have seen. It is really worth to read, to understand and to follow.

If you want to understand what power outages could mean to a society (in a warm region - not in c(o)ld Germany), study the following reports:
Click HERE for the report "Puerto Rico 'heartbreaking' five weeks post-storm"
Click HERE for the report "Puerto Rico Struggles With Power Recovery ..."

I hope something like that will not happen during winter time in Germany.
Note that we have more than natural disasters: Man-made aging infrastructures and aging workforce.

Port Scanning in a Substation - May be a No-Go

Security is more than a buzzword these days. You should be very serious about the security of your substation protection and automation system.
Joe Weiss asked yesterday:
Are the Good Guys as Dangerous as the Bad Guys – an Almost Catastrophic Failure of the Transmission Grid
What happened? A port scanning tool in an IEC 61850 GOOSE based substation protection system had a very negative impact on the GOOSE publisher and subscriber: The Relays stopped to operate!! They had to be manually rebooted.
Port scanning may provide a lot (too much) of stress to the devices and communication system. Such a crucial load has to be taken into account during the design of the devices and of the whole system. Theoretically this payload should be taken into account as part of the system engineering ... part of the System Configuration Description (SCD). Any unexpected traffic avalanche may have a serious impact on the stability of the system!
Click HERE for Joe's report.

I guess that the GridEx network monitor would have raised the red flag seeing the message avalanche in the transmission substation.

Lesson to be learned:
Any non-operational load on a critical network should be treated very careful. IT and OT people have to work together and make sure that such test tools do not put too much stress onto the devices connected in a substation or any other system:
Teamwork makes the dream work - and keeps the power flowing!

Click HERE for a discussion of port scanning ... written long time ago (2001 !!)
Click HERE for a worth to read report on how to apply IEC 62443.

My friend Andrea Bonetti (FMTP) responded as follows:

Dear Karlheinz!
What you have described is unfortunately a known problem.
It is really not at all the first time that it happens in the last 10 years, but it is maybe the first time that it is presented to the public.
I would like to stress-out that this problem is NOT related to IEC 61850 but it is related to the correct usage of digital technology.
Similar situations happened also “before” when proprietary digital technology was used. Maybe they were just more difficult to disclose because also the tools were proprietary.
Regarding GridEx, it would have detected the loss of communication among the devices, as it performs the supervision of the GOOSE messages. This would have been written in its report.
GridEx performs also network load calculations, but in the case you have described this would not have helped probably. Anyway that information would also have been written in the report.
Let me point out that GridEx is an “IEC 61850 passive tool”.
GridEx does not talk to any device, does not send any IEC 61850 message…. it can only listen to what happens, without interacting with the system.
Also the time synchronization of GridEx can be performed completely independently from the system, with its own independent GPS receiver accessory.
Also GridEx works without a PC, so you do not connect the PC to the substation network system.
As GridEx doesn’t interact to the system where it is connected to, it cannot cause any damage and it can be connected to the network while the system is in service.

Wow: IEC Goes XML and PSON

IEC provides access to crucial standardized information by modern web technologies:
The content of the Electropedia (The World's Online Electrotechnical Vocabulary) is now made accessible by XML documents and PSON (REST) through the opendata gateway.
“A json version of all subject areas (or IEV parts) in the Electropedia is available by calling the REST endpoint: “ https://opendata-api.iec.ch/v1/opendata/areas/ 



I expect that the PSON option will be made available for the complete vocabulary soon.
Enjoy!
More to come!

Draft TR IEC 62351-90-2: Deep Packet Inspection (DPI) of Encrypted Communication

IEC TC 57 just published the document 57/1939/DTR:

Power systems management and associated information exchange –
Data and communications security –
IEC TR 62351-90-2: Deep Packet Inspection (DPI) of encrypted communications

This technical report analyses the impact of encrypted communication channels in power systems introduced with IEC 62351. As defined in IEC 62351 an encrypted channel can be employed when communicating with IEDs and encryption can be adopted at message level as well. For example, the use of encrypting TLS setups according to IEC 62351-3 introduces some issues when Deep Packet Inspection (DPI) is needed to inspect the communication channel for monitoring, auditing and validation needs.
In this report we analyze different techniques that can be employed to circumvent this issues when DPI of communications is required.

The voting closes 2017-12-22

ABB Presents the Benefits of Substation Digitalization with IEC 61850

A nice video by ABB (Steven Kunsman) explains "all the benefits of substation digitalization ... it’s little wonder there’s so much interest in the shift to this technology. Supported by the open communication capabilities derived from IEC 61850’s, substation assets are providing a growing volume of health and operational data that’s enabling higher levels of both reliability and performance. This excerpt from an ABB Automation & Customer World Workshop provides key highlights of how the digital substation is also safer, smaller, and simpler to commission and operate than traditional substations."

IEC TC 57 published Two Documents Related to Security Measures (IEC 62351)

IEC TC 57 just published the following two documents:

57/1928/NP
IEC 62351-100-3: Conformance test cases for the IEC 62351-3, the secure communication extension for profiles including TCP/IP

The scope is to specify common available procedures and definitions for conformance and/or interoperability testing of the requirements of IEC 62351-3, the security extension for profiles including TCP/IP.

57/1931/DC
Proposed revision of IEC TS 62351-6 ED1 and conversion into an International Standard (Power systems management and associated information exchange - Data and communications security - Part 6: Security for IEC 61850)

Both documents indicate that the security measures defined by the series IEC 62351 are becoming more important! Hope that more experts in the power delivery domain will understand the impact!
