IEC/TR 61850-90-5:2012 provides a way of exchanging synchrophasor data between PMUs, PDCs WAMPAC (Wide Area Monitoring, Protection, and Control), and between control center applications. The data, to the extent covered in IEEE C37.118-2005, are transported in a way that is compliant to the concepts of IEC 61850. However, given the primary scope and use cases, this document also provides routable profiles for IEC 61850-8-1 GOOSE and IEC 61850-9-2 SV packets. These routable packets can be utilized to transport general IEC 61850 data as well as synchrophasor data.

IEC 61850 in Papers at the CIRED 2011 Conference in Frankfurt (Germany)

One of the topics presented and discussed at the CIRED 2011 Conference in Frankfurt (Germany) was IEC 61850. 15 papers were about IEC 61850 with different objectives and scope.

There seems to be a lot of applications which people have not thought about some five or ten years ago.

One of the key needs seems to be all over to USE the standard for many applications in a FAST TO MARKET approach – instead of discussing one or the other protocol issues. The use of WIMAX applications demonstrates what we have said many times: the layered architecture of IEC 61850 can leverage the progress in communication systems. The same is true for 1 GBit/s Ethernet and time synchronization according to IEC 61588 (IEEE 1588).

The last two papers introduce IEC 61850 for condition monitoring – quite interesting and good examples for the application of IEC 61850 in power distribution.

The last but one paper from ABB (On-line condition monitoring …) says:

“This new circuit breaker (CB) is a highly integrated device that combines measurement, protection and control capability with the primary power disconnection, switching and interruption technology. The CB embeds a protection and control Intelligent Electronic Device (IED) designed to unleash the full potential of the IEC 61850 standard for communication and interoperability. …

Fast delivery
The high technology production line and component standardization enable to guarantee the same delivery time for the new CB series as the standard circuit breaker.”

Fast delivery means fast development. Embedded Controllers with IEC 61850 software already integrated into the platform could provide an easy to use and fast to go API (Application Program Interface). You can start right away with your application development – skip the IEC 61850 software integration that usually may take six to 12 months!!

The first small footprint embedded controller with an integrated IEC 61850 stack providing a simple API is the Beck IPC 61850@CHIP. There will be two other controllers running LINUX available soon that have the same IEC 61850 stack from SystemCorp and the same simple API.

Many IED vendors are already developing their HW and SW applying the Beck IPC Chip for various applications (protection, control, measurements, charging stations, …).

Stay tuned to this Blog to get information on the two new powerful LINUX based embedded controllers with IEC 61850. Product announcements will be released this summer (2011). More to come.

Last but not least: There is still confusion what the Edition 1 and Edition 2 of IEC 61850 mean.

Draft Technical Report - IEC 61850 for Synchrophasor

Draft IEC 61850-90-5 TR Ed. 1 – Use of IEC 61850 to transmit synchrophasor information according to IEEE C37.118 has been published as draft Technical Report (57/1086/DC). Comments by 2010-10-01.

This technical report describes how to use IEC 61850 to transmit synchrophasor information according to IEEE C37.118. Later, once the report is approved and published, results will be integrated as amendments in the relevant parts of the IEC 61850 standard.
This document contains a first draft of that report. As a significant part, it includes new mappings of the IEC 61850 GOOSE and sampled value services that can be used for a wide area communication.

Two new control blocks are defined for IP networks:
• The sending of stream information (e.g. Sampled Values)
• The sending of event driven information (e.g. GOOSE)

Two possibilities are drafted:

The streams for SMV and GOOSE will be transmitted over a transport profile that utilizes IPv4 or IPv6, and TCP as well as UDP.

Once these models are extended in the ACSI (IEC 61850-7-2) they may also be used for Reporting over UDP.
