• CIGRE NGN presentation – how optimistic do you feel about your future career in the power industry and what challenges do you foresee?

12:30 –Networking lunch and end of hybrid session

13:15 – New upcomming challenges

• Gas handling and some other topics from the user’s perspective (like long term performance, asset management and risks, etc)| Matt Barnett
• UK specific DC time constants and alternative gas breaker compliance challenges| Mark Waldron
• Bus transfer, air core reactor and other possible enhancements to standards | Matt Illes
• CIGRE TB 898 Knowledge transfer of substation engineering and experiences | Hugh Cunningham | Knowledge Transfer of Substation Engineering and Experiences
• Open floor discussion – we welcome members to raise new issues or challenges. Are there opportunities that CIGRE should look at?

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

Mission

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

Mission

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.
