NEW: Embedded Linux Gateway supporting IEC 61850 and IEC 61400-25

SSV Embedded Systems (Hannover, Germany) offers the embedded Linux gateway module DIL/NetPC DNP/9265 now with a preinstalled IEC 61850 (IEC 61400-25)protocol stack. An easy to configure and use IEC 61850 API (application program interface) allows for a very short time-to-market development – within days and weeks. Program your application, model the IEC 61850 logical nodes and data object that expose your application data, bind them together, configure the communication services like data sets and control blocks (reporting and GOOSE) – and you can connect with other IEC 61850 devices. The model, the binding, and the communication services are described in a standard SCL file (System Configuration Language, IEC 61850-6) and uploaded to the module. Restart the module and you are done. It’s that easy.

The ARM9-based DNP/9265 is equipped with 32MB of SDRAM, as well as 32MB of NOR flash for holding the boot-loader and Linux O/S, says the company. I/O is passed through a 40-pin DIL socket, and includes three UARTs for COM functions, as well as 20-bit GPIO.

The module supplies one interface each for USB 2.0 Host, SD card, I2C, SPI, and CAN (ISO/11898A 2.0B), says the company. A 10/100Mbps Ethernet port is also supported. Additional features include a watchdog timer, power supervisor for VCC control, and in-system programming features.

Measuring 2.17 x 0.91 inches (55 x 23mm), the module runs on a 3.3 Volt power supply, with supply current at typically 300mA, with a maximum of 500mA. The module is said to support temperatures ranging from 32 to 158 deg. F (0 to 70 deg. C).

SSV also offers other DIL/NetPC-based gateway box products for smart grid and virtual power plant applications. These gateways allow to connect distributed generation installations (such as CHPs, wind-turbines, small hydro, back-up gensets etc.) directly via IEC 61850 with any other application like power grid monitoring or control centers.

In addition to Linux and the integrated IEC 61850 the SSV gateway solutions comes with drivers and protocol stacks for SSL- or IPsec-based VPNs (virtual private networks). This allows secure data communication with powerful encryption technologies over the public telecommunication infrastructure, such as the Internet.

The Aging Workforce in the Electric Power domain

The Electric Power Utility domain is looking for many electrical power engineers all over. One example can be found by searching the simplyhired.com:

Click HERE for a search on power system engineer

The search results in 38,329 hits for the U.S. allone !!
Some 6.000 hits are related to protection, 800 to SCADA, and 55 to IEC 61850, 12 to DNP3.

Click HERE for a search on electrical engineer

The search results in 86,596 hits for the U.S.
72 are related to IEC 61850 and 20 to DNP3.

Power systems require skilled and experienced engineers. How to become an experiences and skilled engineer? By education, training, learning-by-doing, …

During the year 2011 a lot more electric power engineers and IT experts have received one or the other education and training with regard to IEC 61850.

I see a lot more of interest on the radar screen for 2012.

Have you ever thought about to get a training that build up your skills in the application of IEC 61850 and related standards? Note that in many of the open positions you can read something like: experience in relevant protocols and interfaces (IEC 61850, IEC 60870-x, DNP, etc.).

Many people still expect that IEC 61850 is a protocol. It is definitely much more than a protocol.

IEC 61850 soon for Steam and Gas turbines

A New Work Item has been proposed by Sweden to use IEC 61850 for Steam and Gas Turbines (Document 57/1193/NP). IEC 61850-7-410 defines already extensions of the Information models for applications in Hydro Power Plants.

The draft second edition of IEC 61850-7-410 has been extended to cover power system stabilizer (PSS) functions, as well as complex excitation systems. In order to use the IEC 61850 communication system for thermal power plants, additional data models for e.g. steam turbines with ancillary equipment is required. In a further future work, additional models for boilers, burner management, flue gas cleaning could be added.

The ballot of the NP closes 2012-02-17.

If you are interested in getting involved contact your IEC TC 57 National Committee.

Integration of Renewables in the Grid – A Huge Challenge

Sometimes some experts expect that IT is one of the most crucial aspects of the future power delivery system – yes it is important … to some extent.

The Power System is STILL (and forever) an ELECTRICAL SYSTEM! Mark O’Malley writes in the 2011-11/12 issue of the IEEE Power & Energy magazine that the “Grid integration is, in his view, the most interesting and exciting area of research in the world today.” … and tomorrow and for the next decade at least.

After many years of low investments in the power industry (material, equipment, systems, human resources, …) it is expected that it will grow now. Some companies have already increased their budgets for education in Energy and IT related issues.

IEC 61850 Editions – Help to Prevent Confusions

After my recent Newsletter on IEC 61850 many experts visited the blog post of the first discussion on Editions which summarizes:

BUT there will be not an EDITION 2 of the standard SERIES IEC 61850 per se!! Various parts (of the first 16 parts) will be revised and extended and then published tagged as EDITION 2.

New parts will be published with the tag EDITION 1, e.g., IEC 61850-80-1 (Guideline to exchanging information from a CDC-based data model using IEC 60870-5-101 or IEC 60870-5-104) - IEC/TS 61850-80-1, Edition 1.0, 2008-12

Click HERE for the complete post.

There are a lot of confusions when people talk about Editions of IEC 61850.

In a new paper it is reported: “Edition 2.0 of IEC 61850 Standard has been released considering valid technical issues and future aspects of protocol usage. … compares the IEC 61850 Edition 2.0 specification to its predecessor Edition 1.0.”

Click HERE for that paper.

There is hope that experts will use more precise language when it comes to editions of the many parts of IEC 61850 and related documents.

In addition to the question of the Edition of the standard there is another question, when it comes to the Devices that implement IEC 61850: Does this or that Device conform to IEC 61850 Edition 1 or Edition 2?

Since there is NO EDITION 2 of the STANDARD, a Device could NOT be characterized as an IEC 61850 Edition 2 Device!!

We have to differentiate the various aspects of the Standard: Which Logical Nodes, Common Data Classes, Services, which subset of the Configuration Language Edition 2, et cetera are implemented.

Edition 2 of any part of IEC 61850 can mean the following:

  1. (Usually: Most) Definitions of parts tagged Edition 1 have been taken over in the same parts tagged Edition 2 without any change.
  2. (Some) Definitions of parts tagged Edition 1 have been taken over in parts tagged Edition 2 with fixes or minor changes. During the tissue process the parts tagged Edition 1 have already been “fixed” to some extend.
  3. (Less or more) New Definitions have been added in parts tagged Edition 2. [Service tracking in IEC 61850-7-2, many new LNs in IEC 61850-7-4, …]
  4. (Some) Definitions of parts tagged Edition 1 have been moved to parts tagged Edition 2 without changes. [e.g., LN STMP from IEC 61850-7-410 Ed1 to IEC 61850-7-4 Ed2; Substitution has been moved from IEC 61850-7-2 Ed1 to IEC 61850-7-3 Ed2, …] 

A Device A that implements those definitions from several parts tagged Edition 1 that have not changed in Edition 2 of these parts is compliant to edition 2 of these parts without any modifications! If a Device B implements some new features of one or more parts tagged Edition 2, then these new features have to be listed in some detail to understand the situation. Some detail means that the implemented features per part tagged Edition 1 and/or Edition 2 have to be listed.


  1. A Device may just implement a new LN from Edition 2 of part IEC 61850-7-2; the other definitions are used as defined in Edition 1 of the other parts like IEC 61850-7-3, 7-2, 8-1, … So, is this an Edition 1 or Edition 2 Device? Both! But we better do NOT TAG a Device being Edition 1 or Edition 2. It’s a Device implementing the services according to the PICS of part IEC 61850-7-2 Edition 1 (the subset used may be unchanged in Edition 2), IEC 61850-8-1 Edition 1, … and the STMP LN of IEC 61850-7-4 Edition 2.).
  2. The same Device could be understood as implementing the STMP LN according to a part that is tagged Edition1: The STMP LN is still officially published in IEC 61850-7-410 Edition 1. Edition 2 of 7-410 will not have the STMP LN any more – it is already moved to 7-4 Edition 2.

Users should not wait until a Device or the Communication Stack is compliant to Edition 2 of the Standard IEC 61850!! You will never get such a Device because there is NO Edition 2 of IEC 61850. You may want to use one or the other new service of IEC 61850-7-2 Edition 2 (like Service tracking of control block services) or a new LN from IEC 61850-7-2 Edition 2 or from IEC 61850-7-420 Edition 1 or IEC 61850-90-7 Edition 1 …

Always list some details what has been implemented from the various parts tagged Edition 1 or Edition 2 – if you want to prevent confusion. 

Additional discussions on this topic will follow – time permitted.

Stay tuned.

Distribution Company Vector’s Ten-Years Plan for IEC 61850

Vector Limited is the electric power distribution company in the Auckland (New Zealand) area. The company publishes every year an Asset Management Plan (AMP) – informing the public and others what the company is planning to do with their assets. The current plan covers a ten year planning period from 1 April 2011 to 31 March 2021.

One goal of the current AMP is to demonstrate innovation and efficiency improvements. What does this mean related to IEC 61850? A lot in the past and in the future:

  • Vector’s substation automation system is based on resilient optical
    Ethernet local area network running IEC 61850 compliant IEDs.
  • Vector’s current standard for internal and external communication systems is IEC 61850 standard. DNP3 is also used as an interim solution.
  • At present over 50% of Vector’s primary substation are equipped with IEC 61850 compliant IEDs.
  • Vector has been running an annual RTU replacement programme for a number of years, and is currently replacing approximately 10 RTUs per region per annum. To replace conventional RTUs, two approved solutions have been used, traditional RTUs with a migration path to IEC 61850, and fully compliant IEC 61850 solutions.
