A3 -Transmission & Distribution Equipment and B3 -Substations and Electrical Installations Technical Liaison Meeting

University of Manchester | Wednesday 7th February 2024

in person 9:30 – 16:40 | Online 10:00-12:30

About this event

This meeting is to provide a high-level overview of the ongoing activities in CIGRE related to Study Committee A3 (Transmission & Distribution Equipment) and B3 (Substations and Electrical Installations) led by UK Regular Members Matthew Iles (A3) and Mark Osborne (B3). There will be presentations on a variety of topics including challenges with new gas SF6 alternatives, knowledge transfer and other topics pertinent to the industry.

The second goal of this session is to hold open discussions and to encourage sharing of challenges faced by members. Worldwide the power industry is changing quicker than ever, delivering a lot of stuff, delivering it quickly, and frequently adopting new technology faster than is comfortable, or where standards might be lacking or need changing. This is all happening against a backdrop of supply chain constraints, a changing supply market, challenges with non-standard products and requirements, not enough people to do things the way we have done in the past, and all while continuing to manage the old asset fleet. We are aiming to gain a common understanding of the UK challenges and identify potential new work streams or topics of interest for UK members and identify what can do Cigre do to help.

Joining the meeting in-person or online

The regular members for A3 and B3, would like to welcome you to the CIGRE UK A3/B3 Liaison Meeting 2024 taking place at the University of Manchester.

If you are unable to attend in-person, then there is an option to listen in to the morning session from 10am – 12:30 via a Webinar session. Please register ONLY for one or the other option.

Simply register from this page and you will be sent an email confirmation. Details of the Webinar session will be emailed to you 3 days before the event.

There is a small charge of £10 per person to attend to help towards catering costs, however if you are a university student, registration is free.

15:00 – Tea and coffee break

15:20 – Roundtable discussion – Based on the discussion throughout the day, we will put together 3 key topics for further focused discussion with the following aims:

  • How can we meet the challenge? Can we generate examples that can be shared more widely?
  • What would we like to see changing?
  • Can CIGRE be a major part of the solution?

16:20 – Wrap up and closing remarks

16:40 – Target Finish time

A3 – Transmission & Distribution Equipment

A3Mission

To facilitate and promote the progress of engineering and the international exchange of information and knowledge in the field of equipment for distribution and transmission equipment above 1KV. To add value to this information and knowledge by means of synthesizing state-of-the-art practices and developing recommendations.

Scope

SC A3 addresses topics throughout the asset management life-cycle phases; from conception, through research, development, design, production, deployment, operation, and end-of life. At all stages, technical, safety, economic, environmental and social aspects are addressed as well as interactions with, and integration into, the evolving power system and the environment. All aspects of performance, specification, testing and the application of testing techniques are within scope, with a specific focus on the impact of changing interactions and demands due to evolution of the power system. Life cycle assessment techniques, risk management techniques, education and training are also important aspects.

Main areas of attention

Study Committee A3 monitors the evolution of technology and socioeconomic factors in a changing Electric Power Industry. These factors have a direct impact on the progress and development of transmission and distribution systems and thus on Medium, High Voltage and Ultra High Voltage Equipment. The present trends, include the following:

  • Impact of inverter based technologies on T&D equipment.
  • Changing equipment requirements under bilateral power flows, increased stresses on T&D equipment.
  • Influence of severe weather on the equipment.
  • Impact of harmonics on T&D equipment.
  • Implementing the intelligence inside the equipment.
  • Reliability enhancement with advanced sensors and metering, lifetime management, virtual and augmented reality.
  • The interaction of T&D equipment with future High Voltage Networks including the increased introduction of distributed generation.
  • Deregulation and power trading requiring energy flow optimization in networks and increased focus on overload capabilities and properties.
  • MVDC and some HVDC equipment.
  • A growing demand for larger capacity equipment especially for UHV equipment.
  • An increasing maximum short-circuit power in networks.
  • The application of intelligent equipment that allows integration within advanced control and protection schemes.
  • New technologies and possible alternatives to High Voltage Equipment used presently including new switching devices, fault limiters, insulation systems and the measurement of voltage and current.
  • All aspects of Life Management, Condition assessment and Diagnostics.
  • A growing awareness of environmental issues, including the concern over SF6 as a greenhouse gas.
  • The reduced depth of expertise within the industry requiring greater international training and education cooperation.

B3 -Substations and Electrical Installations

B3Mission

To facilitate and promote the progress of engineering and the international exchange of information and knowledge in the field of substations. To add value to this information and knowledge by means of synthesizing state-of-the-art practices and developing recommendations.

Technological field of activity

  • Substations and similar electrical installations.

Scope

Study Committee B3 deals with issues in all phases of the substation lifetime; from conception, through research, development, design, production, deployment, operation and end-of-life. At all stages, technical, safety, economic, environmental and social aspects are addressed, as well as interactions with and integration into the evolving power system and environment. All aspects of performance, specification, testing and the application of testing techniques are within the scope, with particular emphasis on the impact of changing interactions and requirements due to the evolution of the power system. Life cycle assessment techniques, risk management techniques, education and training are also important aspects.

SC B3 maintains close relationships with SC A3 – Transmission and distribution equipment, SC B1 – Insulated cables, SC C3 – Power system environmental performance, C6 – Active distribution systems and distributed energy resources and D1 – Materials and emerging test techniques.

SC B3 members support CIGRE work and activities in extending the electricity system in sub-Saharan Africa and developing countries globally.

Within this framework additional specific areas of attention include:

  • New substation design concepts including new technologies and applications to support energy transitions (on-offshore wind, PV, hydrogen, energy storage, EV charging infrastructure, etc.) and reducing carbon footprint impacts.
  • Lifetime management of substation assets including refurbishment, maintenance, monitoring, reliability and sustainability issues.
  • Substation ownership issues including human resource and training needs, in-service support including quality control, environmental, health, safety and security.
  • Integration of intelligence for substation Digitalization, including new digital technologies (Artificial Intelligence, Internet of Things, 3D technology, etc.) and applications to be used in all types of substations, increased use of advanced information and communication technologies.
