High Voltage Substation (HV Substation)

High Voltage Substations play a critical role as the connection point between solar power plants, Battery Energy Storage Systems (BESS/ESS), and the national grid. They ensure reliable power transmission, voltage transformation, protection, and control of the system.

Advantages:

• Stable transmission of generated power to the national grid

• Voltage transformation from MV up to HV levels of 400 kV

• Comprehensive protection against short-circuits, overloads, and voltage fluctuations

• Capability to integrate renewable energy sources and energy storage systems

• Expandability for future capacity upgrades

Applications:

• Utility-scale solar and wind power plants

• Large industrial and commercial complexes with high energy demand

• Microgrid and BESS integration with the national grid

• Regional and national transmission & distribution projects

Key Features:

• High-efficiency power transformers

• Modern circuit breakers and disconnectors with automation capability

• Advanced and intelligent protection relays

• SCADA monitoring and control systems for precise operation and maintenance

• Robust design for diverse environmental and climatic conditions

• Seamless integration with PV and BESS for grid stability

  • Choice of two technologies:
    • o AIS (Air Insulated Substation): cost-effective, suitable for open outdoor spaces
    • o GIS (Gas Insulated Substation): compact, safe, and ideal for limited-space or sensitive environments
