News from CIGRE Study Committee B5   Protection and Automation

Preparations are underway for the CIGRE Session 2022, which will take place from 28 August to 02 September 2022 at the Palais des Congrès in Paris. SC B5 will host 3 preferential subjects as follows:

  • PS 1:  Addressing Protection Related Challenges in Network with Low-Inertia and Low Fault-Current levels
    • Special Reporter – Sean McGuiness (IE)
  • PS 2: Applications of Emerging Technology for Protection, Automation and Control
    • Special Reporter – Tianshu Bi (CN)
  • PS 3: Integration of Intelligence on Substations (Common PS with B3)
    • Special Reporter – Peter Kreutzer (CH)

The full papers have now been reviewed and authors notified of the outcome and the Special Report is under preparation which will summarize the papers and raise questions for response at the session by way of contributions submitted ahead of the sessions.

PS1 and PS2 will be presented on Friday 2nd September whilst PS 3 will be a joint session with SC B3 (Substations and electrical installations) on the afternoon of Tuesday 30th August.

SC B5 will also host a tutorial on the morning of Tuesday 30th August, titled “System Integrity Protection Schemes in the Context of Evolving Power Grids” with three speakers:

  • Cedric Moors
  • Vladimir Terzija
  • Alex Apostolov

For the four new working groups decided at the SC meeting back in August, Terms of Reference have been drafted and one is already approved and seeking members.

This is B5.77 entitled “Requirements for Information Technologies (IT) and Operational Technology (OT) managed of Protection, Automation and Control Systems (PACS).”

The following two WGs have had their ToRs submitted for approval and will hopefully be able to start their work soon:

  • WG B5.78 – New requirements of network protection and control for renewable energy integration
  • WG B5.79 – Protection Roadmap for Low Inertia and Low Fault Current Networks

The fourth new WG proposal is still being finalized.

Work on the CIGRE ‘Green Book’ by SC B5 is progressing well. This will be titled “IEC 61850 Principles and Applications to Electric Power Systems.”

The draft has been submitted to the publisher, and chapter proofs are expected soon, with the aim of publishing the book in July ahead of the Paris Session, where the book will then be available to purchase or online
