The control stages are the stages at which steam is admitted to or extracted from the turbine. These "control" the output of the turbine.
Stall control when related to wind turbines is actually the angle of the turbine blade. This angle is adjusted with the direction and speed of the wind.Ê
in reaction turbine pressure compounding is employed as every stage has a set of nozzle ring nozzle control is not feasible.
Well Really It Would Depend On What Type Of Water Turbine You HAd Yuo Should Contact The Manufacturer.
DEH Means "Digital Electro-hydraulic Control System" mostly for steam turbine
Which actually Actuates the Steam Control Valve
MARK6 is used for the protection of steam and gas turbine in electrical generators and process plant applications The main function of Mark6 turbine control system are: -speed control during turbine start up -automatic generator synchronization -turbine load control during normal operations on the grid -protection against turbine -protection against turbine over speed on the loss of land The mark6 system is available as a simplex control or a triple modular redundant (TMR) control with single or multiple racks, and local or remote I/O. The I/O interface is designed for direct interface to the sensors and actuators on the turbine, to eliminate the need for interposing instrumentation, and to avid reliability and maintenance issues associated with that instrument. NOTE : to obtain a highest reliability, MARK6 uses a TMR architecture with sophisticated signal voting techniques.
The function of the wasegate valve is to divert exhaust gases away from the turbine in the engine system. This enables it to control the speed of the turbine.
By throttling the amount of fuel delivered to the combustion chamber
this might helpsteam-temperature-control
The device which control the speed of Turbine is Governor. The Governing system sense the speed of shaft & regulate the Fuel/ Motive fluid flow to the Turbine to maintain the set shaft speed.
The fuel control is adjusted to set idle and maximum speed.
