SGT-800 for grid stability

• At a grid black out event, the SGT-800 goes into house load condition

• Full load rejection easily handled

• No restart of the gas turbine required, just re-synchronize to the grid when ready

SGT-800 keeps spinningwhen grid goes black

• Large instant load steps, up to 70% of full load power, can be balanced by SGT-800

• During first seconds, the large inertia of the SGT-800 damps the ROCOF (Rate Of ChangeOf Frequency). Compared to e.g. an aero-derivate GT of similar size, SGT-800 has severaltimes higher inertia, leading to much smaller frequency deviations at a step load adding

Large instant load steps

• Extremely strong primary response rate, up to 600 MW/minute during the first 10 seconds.

• The large single shaft inertia allows fast and strong control response to frequency deviationswithout causing oversensitivity. No spool that needs to change speed at load changes
