Open Source Synchrophasor Framework for IEC 61850-90-5 under development

On October 02, 2011, I announced that the IEC TR 61850-90-5: “Use of IEC 61850 to transmit synchrophasor information according to IEEE C37.118” is on its way for official publication; expected by end of 2011.

To accelerate the application of the technology defined by IEC 61850-90-5, Cisco, Inc. (CSCO) and Systems Integration Specialists Company, Inc. (SISCO) have begun an open source project intended to provide an implementation framework for synchronized phasor measurement communications.

They expect that an “open source project will foster innovation and faster adoption of the standards using IP-multicast and a scalable security architecture´. … For the open source project, Cisco will provide source code for the Group Domain of Interpretation (GDOI) protocol. This protocol provides the type of advanced cyber key management services that are needed to secure communications for power system automation applications, including substation automation and protection, as well as for Smart Grid applications such as metering and demand response. SISCO will provide the source code for the IEC 61850-90-5 communication profile and the integration of that profile with the GDOI code. …”

It is very likely that this project will push the application of IEC 61850 in North America and all over.

IEC 61850-90-5 defines How to Use IEC 61850 to transmit synchrophasor information according to IEEE C37.118

The new Technical Report IEC TR 61850-90-5: “Use of IEC 61850 to transmit synchrophasor information according to IEEE C37.118” is on its way for official publication.

Synchrophasor information are measured and calculated by PMUs (Phasor Measurement Units) are used to assess the condition of the electrical power delivery system. The synchrophasors and related message formats transmit synchrophasor information over long distances. The payload is defined in IEEE C37.118.

IEC 61850-90-5 will provide a way of exchanging synchrophasor information between PMUs and WAMPAC (Wide Area Monitoring, Protection, and Control), and for and between control center applications.

IEC 61850-90-5 also provides communication profile extensions to allow to route GOOSE and sampled value messages (IEC 61850-8-1 and IEC 61850-9-2) using UDP/IP. These routable messages can be utilized to transport any IEC 61850 information as well as synchrophasor information.

Applications comprise:

• Synchro-check
• Adaptive relaying
• Out-of-step (OOS) protection
• Situational awareness
• State Estimation and on-line security assessment
• Archive data (event & continuous)
• Special Protection Schemes
• Predictive Dynamic Stability Maintaining System
• Under Voltage Load Shedding
