Control of a blow-off valve responsive to a sudden de-loading of a gas turbine

For the sake of improving a control system for a gas turbine system having a compressor, a combustion chamber, a flue gas exhaust stage, a driveshaft and a blow-off valve assembly that selectively provides fluid communication between the compressor and the flue gas exhaust stage, the present disclosure teaches a control system comprising a controller configured and adapted to signal the blow-off assembly to provide the fluid communication in response to a sudden de-loading of the gas turbine.
