Digitalising Operations: Innovation at Substations

New switchgear designs focus on digitalisation of substations.

 

Cutting Edge Innovations include digitalization of substations, application of Gas-Insulated Switchgear (GIS), combination of GIS with Air Insulated Switchgear (AIS) in hybrid switchgear, wider adoption of vacuum switchgear, as well as application of Solid Insulation Switchgear (SIS).

Emerging Trends

  • 3D Modelling: 3D modelling software for substations ensures efficient management of complex infrastructures, including large substations with different voltage levels. It includes tools for lightning protection calculation, phase checking, clearance calculation, and short-circuit current effect assessment.
  • Condition Monitoring Systems: These systems acquire and analyze transformer data to predict potential failures. They are rugged, compact, cost-effective, and support advanced communication protocols like IEC 61850 and MODBUS for seamless integration with control rooms.
  • Eco-Friendly Construction: Using bamboo as an alternative to steel reinforcement in concrete construction is an advancement in eco-friendly building methods. Bamboo-reinforced columns exhibit significant improvements in axial compression capacity compared to plain concrete.

Growth Drivers

  • Urbanization and Industrialization: Increasing electricity demand due to urbanization and industrialization drives the need for reliable power transmission and distribution infrastructure.
  • Government Initiatives: Programs like the Revamped Distribution Sector Scheme (RDSS) enhance grid efficiency and reliability, driving demand for new and upgraded substations.
  • Renewable Energy Integration: The growing focus on integrating renewable energy sources into the grid promotes the demand for modern substations and switchgear.
  • Technological Advancements: Adoption of digital substations, smart switchgear, and advanced protection systems enhances operational efficiency and attracts investments.

Conclusion

The substation and switchgear market is evolving with innovations that address utilities’ needs for compact, reliable, and environmentally sustainable solutions. Upgrading infrastructure and digitizing operations are essential for ensuring a reliable power supply and reducing costs. As renewable energy integration increases, the demand for modern substations and switchgear will continue to grow, supporting the expansion of transmission and distribution networks.
