World-first disaster recovery solution

8 September 2020

Hitachi ABB Power Grids has pioneered what it believes is a ground-breaking modular mobile substation solution which greatly reduces the time to restore power in the case of major disruptive events such as natural disasters.

This world-first 400 kV multi-voltage modular mobile substation system can be rapidly deployed and installed to restore power from an average duration of 18 months – required for the new build of a conventional substation – to only seven days. Each mobile substation, equipped with high-voltage hybrid switchgear and protection and control solutions, is compact in design and ready for fast energisation. 

Niklas Persson, managing director of the Grid Integration Business Unit at Hitachi ABB Power Grids commented: “Disruptions to energy provision can result in severe consequences, which is why we are continuously innovating technologies, such as this modular mobile substation disaster recovery solution, to enable customers to provide stable and competitive sources of power and further reduce carbon emissions.”

The substation concept has been designed to ensure long-term grid stability and power quality to regions particularly prone to unpredictable events and natural disasters, such as storms, flooding and earthquakes. Hitachi ABB designs and builds the modular solution, providing ongoing preventive maintenance to ensure the equipment is ready 24/7 to replace an existing substation in a rapid timeframe.

The modular concept means the unit is highly configurable according to a customer’s specific needs, which means it can replace different voltage range and standards of the grid. The factory-tested unit can be installed and deployed within hours, proving a fast solution for utilities and industries that need to quickly provide interim grid connections and temporary power supplies.

These modules require no civil works, have reduced site activities, pose lower risks and come in the form of ready-to-connect, complete assemblies that are designed for grid code compliance and easy mobility. They exhibit limited space requirements, says their maker, and easy transportation from warehouse to site on trailers that are part of the modular system.
