Program & Main Topics

The Colloquium will last for four days. Papers will be presented in the morning and afternoon, in oral sessions and poster sessions, and a CIGRE tutorial will be held as well. Papers regarding all aspects of rotating electrical machines (synchronous and asynchronous) and power generation are encouraged. The papers will be divided into seven main topics:

1. Advanced Design and Numerical Modelling of Electrical Machines

  • Electromagnetic, thermal, mechanical, and coupled-field analytical and numerical modelling
  • Virtual prototyping, and the development of digital twins
  • Design and optimisation of high-efficiency, high-speed, and superconducting machines
  • Multiphysics design challenges in specialised industrial and transport applications

2. Operation and Performance of Converter-Fed Rotating Machines

  • Impact of high-frequency power electronics and fast-switching transients on machine insulation systems
  • Loss evaluation, stray load losses, and advanced cooling system optimisation
  • Mitigation strategies for shaft voltages, bearing currents, and electromagnetic interference (EMI)
  • Operational behaviour of machines under non-sinusoidal supply conditions

3. Large Power Generators, Industrial Motors, and Grid Support Equipment

  • Development, factory testing, site commissioning, and revitalisation of large turbogenerators, hydrogenerators, pumped-storage units, and high-power industrial motors (including large induction and synchronous machines)
  • Synchronous compensators and high-inertia machine design and performance for grid stability and voltage support
  • Advanced excitation systems, automatic voltage regulators (AVRs), and auxiliary equipment for enhanced power system stability and fault ride-through

4. Advanced Materials, Components, and Manufacturing Technologies

  • Novel magnetic materials, including amorphous and nanocrystalline alloys, and high-performance electrical steels
  • Next-generation electrical insulation systems, high-temperature materials, and thermally conductive resins
  • Application of additive manufacturing (3D printing) and innovative winding technologies in electrical machines

5. Diagnostics, Monitoring, and Asset Management

  • Online condition monitoring, advanced sensor technologies, and non-destructive testing
  • Predictive maintenance strategies, remaining life prognosis, and AI-driven health index modelling
  • End-to-end lifecycle management, life extension, refurbishment, retrofitting, and uprating strategies for ageing assets

6. Sustainable Generation, Storage, and Hybrid Energy Schemes

  • Evolving design and operational requirements for power generation equipment in renewable energy systems (wind, hydro, solar, tidal, geothermal, and biomass)
  • Hybrid power generation and storage schemes, co-located battery integration, and electromechanical conversion in microgrids
  • Impact of high renewable energy integration on machine duty cycles, fatigue, and grid code compliance
  • Sustainability, recycling, circular economy practices, and environmental impact assessments for energy assets

7. E-Mobility and Specialised Traction Drives

  • High-power-density motor drives and advanced topologies (e.g., permanent magnet, synchronous reluctance) for electric vehicles, heavy transport, marine and aviation propulsion
  • Modelling, electro-thermal management, and safety optimisation of battery storage packs and fuel cell integration
  • Grid integration challenges, charging infrastructure dynamics, vehicle-to-grid (V2G) interactions, and future technology trends
