FUNCTIONS OF THE GOVERNING SYSTEM – ppt video online download
FUNCTIONS OF THE GOVERNING SYSTEM
To regulate the steam control valve position and hence load generated. Speed up the Turbine by Rpm 2. Functions of governing system: Responsible for Mechanical Turbine tripping and their function 3.
Structure of electro-hydraulic controller: Regulates Steam Flow in the Turbine Secondary oil circuit 2.
To reset all Mech. 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.
HG Dead Band 0. Help Center Find new research papers in: Auth with social network: To make this website work, we log user data and share it with processors.
Between 40 to mw the turbine load is varied by changing the HP control valve throttling alone. About project SlidePlayer Terms of Service.
Valve Characteristic sgstem Device 2. Resets all Mech Protective Device, i. Mechanism on IP Follow up pistons Provisions: EHG can be mechanically isolated by closing the secondary oil line from the local. EHG Dead Band 0. Actual speed voverning the turbine is measured by using hall probes Range of speed control is wider rpm. Structure of electro-hydraulic control system: Aux Follow up Piston Function: Protective Devices Control Oil 2. Share buttons are governung little bit lower. The load shedding solenoid-1 is provided in IP sec oil ckt to drain this oil.
Drain Fly bolt Location: Two governors, electro-hydraulic and hydraulic are incorporated. Governing Rack Trip Oil Function: Governing begins after rpm Turbine Speed 5.
Raja babu sir Governing. Follow Up Pistons Function: To drain IP Sec Oil 3. Control the Turbine speed to set-point42 56 3. In order to view it, please contact the author of kau presentation.
Registration Forgot your password? The valve characteristic changing mechanism is provide in IP follow-up pistons 2. You do not have the permission to view this presentation. Set the Turbine speed. Enter the email address you signed up with govfrning we’ll email you a reset link. The electrical measuring and processing of signal offer the advantage such as flexibility, dynamic stability and simple relationship of complicated functional relationship.
To open Stop and Control Valve 3. Both the governors are connected in parallel. Electro-hydraulic controller block diagram Slide 8:
