Use of IEC 61400-25 to secure access to key O&M data

Vattenfall (one of the big European power utilities) plans to use IEC 61400-25 (an extension of IEC 61850) for operational and maintenance (service) applications.

Here is the conclusion of the paper:
”The IEC 61400-25 series of standards provides the means to get open and easy access to key O&M data [operation and maintenance data]. This data is a necessity for making the evaluations and analysis needed to improve operation and maintenance of the wind power plants. The paper has shown how the standard can be implemented and what benefits are associated with its use.
The standard does not restrict nor mandate specific customer-supplier roles, but provides a solution that supports the whole range of business cases where the different actors can cooperate. Both the customer and the supplier can benefit from IEC 61400-25 through decreased costs for data access and system integration. Time and money can instead be put on the development of applications, functions and methods that increase the performance of the wind turbines.
Vattenfall considers standards such as IEC 61400-25 to be an important part in the development of the wind power business. The IEC 61400-25 series of standards is therefore part of Vattenfall technical requirements for future procurements.”

The same is true for any other energy resource feeding electric energy into the grid – at any voltage level. The renewable resources and – more general – distributed energy resources (DER) are key for the future electric power delivery system. A government funded project in Germany (EUMONIS: Innovationsallianz zur Entwicklung einer Software- und Systemplattform für Energie- und Umweltmonitoringsysteme) is looking for accessing, storing and using information from the sheer unlimited number of power resources in the near future: PV, CHP, hydro, wind, flying wheels, … One objective is to have information about the status and availability of the resource in a central database, in order to operate and maintain the “distributed Power Plant”. This seems to be one of the crucial challenges in the years to come.

Did you know that IEC 61400-25 covers also Condition Monitoring needs?

IEC 61400-25-6 has been Approved as International Standard

The 6th part of IEC 61400-25 has been approved as International Standard on October 15, 2010. The final draft (FDIS) has been approved by 100 per cent of the IEC TC 88 national committees. The Standard will be published in some weeks.

IEC 61400-25-6 Ed.1: Wind Turbines - Part 25-6: Communications for monitoring and control of wind power plants - Logical node classes and data classes for condition monitoring

The new International Standard defines new information models.

IEC 61400-25-6 FDIS Ballot

The last step towards another International Standard for Information models (Logical Nodes; these LNs can be implemented using IEC 61850 compliant stacks) will start August 13, 2010:

IEC 61400-25-6 Ed.1
Wind Turbines - Part 25-6: Communications for monitoring and control of wind power plants - Logical node classes and data classes for condition monitoring
(88/377/FDIS)

The ballot is open from August 13 to October 15, 2010.

This part of the IEC 61400-25 series specifies the information models related to condition monitoring for wind power plants and the information exchange of data values related to these models.

Condition monitoring is mainly based on the following kinds of information:

• Time waveform records (samples) of a specific time interval to be exchanged in real-time or by files for analysis (e.g. acceleration, position detection, speed, stress detection).
• Status information and measurements (synchronized with the waveform records) representing the Turbine Operation Conditions.
• Results of Time waveform record analysis of vibration data (scalar values, array values, statistical values, historical (statistical) values, counters and status information).
• Results of analysis for example oil debris.

IEC 61850 for condition monitoring diagnosis and analysis

The IEC TC 57 (document: 57/1007/DC) has invited for a new project to extend IEC 61850 and use it for CMD (Condition Monitoring Diagnosis) to diagnose the power grid health status to improve the reliability of the power system by preventing a potential failure in advance. Too many different CMD solutions in various forms from many vendors are currently used - there is need to standardize the basic information models and information exchange within IEC TC57.

It is intended to first write a report that addresses communication aspects related to specific sensor networks that are widely used as well as information exchange towards asset management systems. It is proposed to publish that report as IEC 61850-90-3.

A task force within TC57 WG10 will prepare this report. The proposed project leader is: Mr Hyuk Soo Jang, Department of Computer Software, Myong Ji Univ. Yongin, 449-728 Korea.

The TC57 P-members are invited to submit comments to this proposal and nominate experts willing to participate in that work
by 2009-07-03.

Please contact your TC 57 National Committee to receive a copy of the Invitation (57/1007/DC).

The work will address condition monitoring of equipment handled by the following technical committees of IEC: TC11 (Overhead lines), TC14 (Power Transformers), TC17 (Switchgear), TC20 (Electrical cables) and TC38 (Instrument transformers).
In addition, coordination with the work done in TC88, IEC 61400-25-6 (Condition monitoring for wind power plants) is required.

Proposed Architecture:

Implementations of IEC 61400-25-6

Questions: I work at xx unit of utility-industry in xxx and help some energy companies with their future IT support for the handling of wind power production.
This also leads to some help with the requirements of the position before the contracts. I have a long background from both SCADA and maintenance systems.
Saw on the Internet that you are the project manager for IEC 61400-25-6 for Condition Monitoring and want to ask a few questions I hope you will be friendly to answer.

Question 1: What is the status of the expanded standard for Condition Monitoring IEC 61400-25-6?

The project team TC 88 PT is preparing the so-called FDIS document (final draft international standard). We have our next meeting scheduled for next week at DS in Copenhagen.

I hope that we reach the standard in June or so.

Question 2: How far has the commercial deployment come?

The part 25-6 uses parts 25-2 (many information models for WPP - some can be used for condition monitoring) and 25-4 (service mappings) and IEC 61850. The core software to be implemented is according to IEC 61850 ... IEC 61850 is widely deployed for substation automation systems. Most of the software etc can be re-used for 25 and 25-6.

IEC 61400-25 support is offered by e.g. Beckhoff:

and by Bachmann:

Question 3: Which vendors have implemented server and client?

Servers: see above.

Clients are available from various vendors: ABB, Siemens, ...

http://iec61850-news.blogspot.com/search?q=siemens

Question 3: Are there any deployed system? Operating Experience?

A lot with IEC 61850!! Siemens reported that they have installed 50.000+ devices and 1.000+ systems.

Most of these experiences could be applied for wind power applications and especially for condition monitoring.

There is a lot of very good experience!
