Data Centers and Uninterruptible Power Supply (UPS)

Stand-alone power plants in remote sites or on critical applications like data centers, need fast response generation sets that can provide a stable local grid if normal power supplies have faulted or if they are behind the meter (BTM) systems not connected to the utility power grid.

The SSS Clutch enables the generator to remain synchronised to the grid with the prime mover shutdown. The generator spins to provide immediate rotating inertia for frequency control, reactive power for voltage support and high fault current.

As the generator is already synchronised, the prime mover can start quickly and provide active power very fast with battery or flywheel energy storage to bridge the gap between grid interrupt and prime mover generation or where the load changes rapidly.

On BTM systems with multiple power plants, the prime mover on standby generation sets can be shutdown, saving fuel and reducing maintenance costs while keeping the respective generators spinning as synchronous condensers.

SSS Clutches have been used on more than 1200 UPS systems globally and can accept very fast acceleration rates. On sensitive load applications, where the supply changeovers must be seamless, low accelerations are adopted, in either case the SSS Clutch is fully mechanical and automatic.
