The structure of electro- hydraulic controller is comprises of following sub-control loops: Responsible for Mechanical Turbine tripping and their function 3. Generates Trip systemm Aux Trip Oil. Valve Characteristic changing Device 2. Governing system can, therefore be preliminary defined as the system designed to achieve functional requirement of turbo-generator operation by controlling and regulating steam turbine input parameters viz.
Between 40 to mw the turbine load is varied by changing the HP foverning valve throttling alone. To drain IP Sec Oil 3.
