Megger Offers a Wide Range of IEC 61850 GOOSE Test Tools and Experiences


Megger (Sweden) offers a wide range of test tools and experiences for testing and commissioning of systems based on IEC 61850 GOOSE.

They just published a brochure that shares some light on IEC 61850 interoperability problems and solutions for the horizontal communication (GOOSE):

IEC 61850 - GOOSE Interoperability

Click HERE for the brochure.

This document (written by one of the most experienced senior protection engineers) is really worth to download and to read! Andrea Bonetti will give you a deep inside look into the use of GOOSE messaging and how to reach interoperability.

"Interoperability is one of the most misunderstood of all business terms. It is, however, one of the most important of all predictors of success or failure. In short, interoperability is the ability of diverse systems to work together effectively and efficiently. Interoperability is a property of a product or system, whose interfaces are completely understood, to work with other products or systems, present or future, without any restricted access or implementation.

There is absolutely no doubt that Interoperability facilitates valuable business connections—across
processes, between people and information and among companies. Interoperability yields improved
collaboration and ultimately increased productivity. Providing interoperability helps customers decrease complexity and better manage heterogeneous environments—while enhancing choice and innovation in the market. Importantly, the interoperability requirement of the IEC 61850 standard has beneficially increased the “interoperability among different engineers” working for companies that are formally in competition. This increased communication among different vendors has contributed to the fact that GOOSE messaging can today be considered a working technology, even if problems still arise, like in any other technology.

With more than six years of field experience with IEC 61850 GOOSE communication in protection and control applications, it is possible today to list the main reasons for interoperability problems for multi- and single-vendor systems; however, the list of causes of interoperability failures would be longer than what indicated in this document, especially if considering the cases found during the beginning of the use of GOOSE messages.

In order to commission substations with the new IEC 61850 technology, there is need to use some new tools and methods. The key for these tools and methods is, paradoxically, implicitly available in the IEC 61850 standard itself."

Enjoy!

IEC 61850-90-11 - Modelling of Logics for IEC 61850 Based Applications

IEC TC 57 just published a 50+ page proposal for a very interesting topic:

57/2001/DC

Proposed 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 to this draft are expected by 2018-07-27 at the latest.

This is likely the first time where application modelling (using a single configuration language!) integrates basic logic functions like AND, OR, Timer, ... including a Mapping of IEC 61850 data types and IEC 61131-3 / PLC Open XML data types.

The document introduces a couple of use cases describing mainly the control and monitoring of switchgears and electrical measurements.

Use case 1 – Busbar disconnector coupled in a double busbar arrangement
Use case 2 – Delayed breaker trip and blocking after 1st low gas pressure alarm
Use case 3 – Bay connected to busbar A
Use case 4 – Definite trip
Use case 5 – "Direct transfer open operation"
Use case 6 – Line outage detection in a breaker and a half scheme
Use case 7 – Unit trip logic
Use case 8 – Data quality management
Use case 9 – Switchgear control on the example of a busbar change-over

The modelling of logics could be of interest for many other applications.
