IEC 61850 für Smart Grids in Deutschland

BDEW und ZVEI empfehlen acht “reife” und notwendige Technologien für den unmittelbaren Einsatz für Smart Grids:

Smart Grids in Deutschland – Handlungsfelder für Verteilnetzbetreiber auf dem Weg zu intelligenten Netzen (27. März 2012)

“Um die Verteilnetze effizient zu gestalten, erhöht sich der Bedarf an
Messung, Regelung und Automatisierung. Aus Sicht eines Verteilnetzbetreibers kommt es jetzt darauf an, die wichtigsten Technologien und deren Wirksamkeit zu identifizieren. Es stellt sich die Frage, welche Technologien bereits heute zur Verfügung stehen und welches Potenzial diese zur Lösung der verteilnetzspezifischen Probleme mitbringen.”

Von 25 Smart-Grid-Komponenten gelten acht als „erfolgversprechend“:

• Sensorik im Netz,
• Netzleittechnik,
• Kommunikations- und Dateninfrastruktur,
• regelbare Windkraft,
• regelbare Photovoltaik,
• kleinere KWK-Anlagen,
• Pumpspeicherkraftwerke sowie
• Komponenten zur Blindleistungskompensation.

“Als etablierte Kommunikationsstandards in der Energieverteilung liegt die Verwendung der IEC 61850 nahe. Die IEC 61850 erlaubt einen sicheren und effektiven Datenaustausch zwischen den Smart IEDs und das übergreifende Nutzen von Sensoren und Aktoren. … Die konsequente Umsetzung des gemeinsamen Systemstandards IEC 61850 über alle Spannungsebenen hinweg, bietet die Voraussetzung für einheitliche Kommunikations- und Datenstrukturen. Dies ist eine Voraussetzung für den wirtschaftlichen Ausbau der Verteilnetz-Automatisierung.

Flexible und intelligente Stromnetze sind in aller Munde - die dafür nötigen Kommunikationssysteme und Normen werden allerdings gerade erst entwickelt. Experte Karlheinz Schwarz wird die globalen Entwicklungen von nationalen und internationalen Roadmaps und Normen vorstellen.

Im Rahmen der nachhaltigen Weiterentwicklung der Versorgungssysteme muss mit den verfügbaren Ressourcen (Energiequellen, technischen Einrichtungen und Menschen mit Erfahrung) sowie den physikalischen Gesetzmäßigkeiten verantwortungsvoll und "smart" umgegangen werden. Smart Grids helfen, die Physik zum Wohl der Menschen sicher und zuverlässig nutzbar zu machen - gestern, heute und morgen.

Es werden globale Entwicklungen von nationalen und internationalen Roadmaps (DIN, CEN/CENELEC/ETSI, NIST, Chinese State Grid, IEC usw.) und Normen (IEC 61850, IEC 61968/70 CIM usw.) vorgestellt, die helfen werden, die Energieversorgungsnetze auch unter geänderten Randbedingungen sicher und zuverlässig zu erhalten.

Smart Grids – A 19th century invention

Intelligent, safe electrical power distribution networks were invented at the start of electrification and have been further developed up to the present day. Electrical fuses, protective devices and monitoring devices have been phenomenal in the protection of life and technical installations for more than 100 years. Without these "smart" devices a fault-free, fail-safe electrical energy supply system would be inconceivable and the supply of electrical energy much too dangerous.

Since the 19th century engineers have developed, tested, used on a large-scale and continuously improved suitable solutions for the safe and reliable operation of the rapidly growing supply of ever more applications with electrical energy. During the sustained further development of the supply systems, it is necessary to handle the available resources (energy sources, technical installations and individuals with experience) as well as the laws of physics both responsibly and in a "smart" manner.
Smart grids help to make it possible to use physics safely and reliably for the benefit of man – in the past, today and in the future.

A new paper discusses some aspects of the development of Smart Grids.

IEC 61850 Gateway And Programmable IED

These days many vendors that have to develop devices for the electric power delivery are interested in applying a third-party Gateway that map the commonly used protocols like DNP3, Modbus, IEC 60870-5-10x, or CAN bus to an IEC 61850 Server. There are ready-to-go gateway available.

Usually the gateways map between one other protocol and an IEC 61850 Server – if you want to have two or three protocols to be mapped to IEC 61850 you likely have to pay a license for each protocol. The gateways usually are just gateways and do not allow any other application running on the same platform providing application data through IEC 61850 models and services.

The Gateway provided by SystemCorp is quite different as the following figure depicts:

In addition to the Gateway functionality any other application programmed on the very same platform can provide data exchange with the IEC 61850 server through the simple API of the IEC 61850 stack. Various embedded controllers like the Beck IPC Chip provide these possibilities.

This allows with one IEC 61850 license to implement gateway functionalities AND let any other application functionality “speak” IEC 61850.

Wireless Temperature Sensors for Switchgears and IEC 61850

Monitoring the temperature of likely failure points within electric power switchgear provides invaluable data on the health of that piece of equipment. Wireless solutions for temperature monitoring of medium-voltage and high-voltage switchgear are appropriate means to get critical information about the health of switchgears – especially for aging switchgears that have an ever more crucial impact on the reliability of the electric power system.

Ruggedized passive wireless radio-based temperature sensor and monitoring systems are a great answer for medium-voltage and high-voltage electric power switchgear. The access to the these measured temperature values through IEC 61850 is now available by Intellisaw.

Access the Intellisaw website to read the benefits of their Wireless sensors.

IETF Energy Management WG (EMAN) inspired by IEC 61850 and CIM

IETF EMAN, Energy Management, is an active WG that is modeling (in the MIB) a lot of power related real world objects “connected” one way or the other to a network.  SNMP is used to access this information. The objective of Energy Management (EMAN) is to provide an energy management framework for networked devices.

Networked devices could be Ethernet switches, routers, battery controller, other storages,  gateways, … more or less anything that is connected to a network!

http://tools.ietf.org/wg/eman/

The WG sees IEC 61850 as the most applicable standard to EMAN. Concepts from IEC 61850 and CIM have been reused (somehow) by the EMAN WG. A closer cooperation of the models would be appreciated by the next generation of engineers and programmers …

There is ONE real world – many models could be thought of to describe that single real world. I hope that for energy applications we will prevent to get too many models. IEC 61850 models should be used as default solution in all devices closely connected to the physical level of energy systems … different notations and protocols may be used BUT the content/semantic should be identical!

A MMXU should model the 3-phase electrical system – all over and in all models.

Australia: The Dutch Disease and IEC 61850!?

Dustin Tessier suggests in his paper the increased application of IEC 61850 in Australia as a means against the Dutch Disease – a very interesting paper. He states:
“With a bit of sponsorship from the government, this cost saving technology [IEC 61850] established in 2004 - could immediately translate into production efficiencies throughout the utility, LNG, and industrial sectors. This is but one example of low lying fruit that have yet to be picked in the Australian productivity domain.”

The Dutch Disease is a serious threat against nations that have a high dependency on their exportable resource commodities; which explains the apparent relationship between the increase in exploitation of natural resources and a decline in the manufacturing sector.  Nations that are victim to low productivity rates, are more vulnerable than others, and it is these nations that must first seek the "low lying fruit" when trying to stimulate efficiencies within their economy. The answer? IEC 61850! This is an attractive technology, as it applies across most industries, be it utilities, LNG, metals and mining, desalination plants, etc. With a bit of sponsorship from the government, this cost – saving technology established in 2004 – could immediately translate into production efficiencies throughout the utility, LNG, and industrial sectors. This is but one example of low lying fruit that have yet to be picked in the Australian productivity domain. This is likely true for Canada, Brazil, …

According to Wikipedia “the Dutch disease is a concept that explains the apparent relationship between the increase in exploitation of natural resources and a decline in the manufacturing sector. The mechanism is that an increase in revenues from natural resources (or inflows of foreign aid) will make a given nation's currency stronger compared to that of other nations (manifest in an exchange rate), resulting in the nation's other exports becoming more expensive for other countries to buy, making the manufacturing sector less competitive.”

New Release of NIST Framework and Roadmap for Smart Grid Interoperability Standards

DoE (U.S. Department of Commerce) and NIST (National Institute of Standards and Technology) have published an updated roadmap for the Smart Grids (Release 2.0) the other day.

The general direction and objectives of the framework and roadmap described in the first release have been approved by release 2. Several topics of Release 1.0 have been improved and extended. IEC 61850 (and other IEC TC 57 standards like 60870-6 TASE.2/ICCP, IEC 61968/70 CIM, and IEC 62351 Security) are still understood as key standards for Smart Grids.

New aspects covered:

• Developments related to ensuring cybersecurity for the Smart Grid, including a Risk Management Framework to provide guidance on security practices;
• A new framework for testing the conformity of devices and systems to be connected to the Smart Grid—the Interoperability Process Reference Manual; and
• An overview of future areas of work, e.g.,electromagnetic disturbance and interference.

You can read between the lines that the people in charge for smart(er) grids have understood that the implementation of new devices and systems is more a marathon than a sprint. Take a look at the process of standardization of IEC 61850 which started in 1995, released first complete set mainly in 2004-2005, and extended the standard since then. It took many years before the market saw a bunch of vendors and users that implemented the standard (2007 - 2010). But: The pace in implementing and using the standard has increased steadily all over since 2010 – 15 years after IEC 61850 standardization work started, some 20 years after UCA 2.0 was initiated, and 25 years after the MAP project started.

Don’t worry if you see a lot of legacy stuff still running and commissioned. Keep in mind: Haste makes waste. Take your time.

Easy, Affordable and Fast Integration of IEC 61850 in Small Devices

High financial and time expenditures for the implementation of IEC 61850 in control systems and other devices prevented so far a broad market penetration of the standard in the lower voltage levels and in distributed power generation. A reasonable and cost effective solution is now available with the Beck IPC@CHIP. The development of IEC 61850 conformant interfaces in power delivery systems – particularly renewable and decentralized power producers and consumers – can now be realized within very short time to market.

The stack and API used on many platforms has been developed by SystemCorp (Bentley, Western Australia), e.g., on the Beck IPC Chip.

A new paper has been written about the benefits of using ready-to-go solutions. The paper discusses embedded controller with IEC 61850 stack and API, DLL and other libraries with IEC 61850 stack and API, … You will find also a brief discussion of the information models for PV inverters (IEC 61850-90-7).

Video on the Use of IEC 61850-6 SCL to configure a server and a client

This presentation explains the use of two IED specific SCL files to configure IEDs. One is used to configure a server and the second (with the same model - but different bindings between the model and the real data) is used to configure a client. The API "Write call " at the client and the "Write callback" at the server are briefly explained. The API is provided by SystemCorp (Bentley, Western Australia). The API is available at the Beck IPC Chip and other embedded controllers, or for Windows (DLL) and Linux.

Click HERE for an evaluation kit running on a PC (with DLL and applications). The evaluation package runs for six months. It uses two SCL files for configuring the server and the client (as shown in the video).

Video with brief Introduction to IEC 61850 and IEC 61400-25

IEC 61850 and IEC 61400-25 comprise some 25 documents. Part IEC 61850-7-1 contains some basic modeling concepts that may help to get a few ideas what IEC 61850 is about. I guess that just a few people have read that part. In my training courses with almost 3.000 attendees I have gained a lot of experience on how to explain the basic concepts. In 2011 I have conducted more than 30 training sessions (from one to 12 days). Today I am starting a new service to the industry: providing videos that explain basics with animated up-to-date slides.

The first video is a brief presentation of the key concepts of IEC 61850 (one slide): modeling methods, models, configuration language, communication, and mappings. The demonstration shows how these concepts are used to compose a system. Of course, this slide is just showing the basics of a “small system”. This slide is part of the introduction of my commercial training curses.
