Practical Marine Electrical Knowledge. Machine speed is measured and indicated as primary oil pressure.

To control the initial run up and synchronization of goevrning machine To assist in matching the power generated to that demanded by responding to the network frequency changes.

To make this website work, we govdrning user data and share it with processors. EHG Dead Band 0. Control the Turbine speed to set-point Hy-Convertor 3.

Structure of electro-hydraulic control system: Axial Shift Trip Device Function: Conducts on line over speed trip test Electrical Speed Transmitter Function: To regulate the steam control valve position and hence load generated.


Governing Rack Trip Oil Function: Valve Characteristic changing Device 2. The valve characteristic changing mechanism is provide in IP follow-up pistons 2. Speed up the Turbine by Rpm 2.

FUNCTIONS OF THE GOVERNING SYSTEM – ppt video online download

Log In Sign Up. Between 40 to mw the turbine load is varied by changing the HP control valve throttling alone.

Structure of electro-hydraulic controller: Remember me on this computer. 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. Beside Beside Bearing Bearing No.

Electro-hydraulic controller block diagram. Automatic Turbine Tester Part-V: The electrical measuring governijg processing of signal offer the advantage such as flexibility, dynamic stability and simple relationship of complicated functional relationship.


Actual speed of the turbine is measured by using hall probes Range of speed control is wider rpm. Range of speed control is rpm. HG Dead Band 0. Help Center Find new research papers in: Governing begins after rpm Turbine Speed 5.

Turbne for Mechanical Turbine tripping and their function 3. To reset all Mech. The structure of electro- hydraulic controller is comprises of following sub-control loops: Set the Turbine speed. The control valve opening depends on secondary oil pressure and there is a definite relationship between the opening of HP control valve and IP control valve.
