2. Hydraulic System

Reservoir → Intake → Trash Rack → Headrace (canal/tunnel) → Forebay → Penstock → Surge Tank → Turbine → Draft Tube → Tailrace → River

3. Mechanical System

Water Flow → Runner Blades → Shaft Rotation → Generator Coupling → Rotor Rotation → Electrical Energy

4. Electrical System

Generator → Step-up Transformer → Switchyard → Transmission Line → Grid

5. Control System

Sensors → PLC/RTU → SCADA → Operator Interface

• Governor: Speed/Load Control
• AVR: Voltage Control
• Protection: Fault Detection & Isolation

Pelton Turbine (Impulse)

• Principle: Kinetic energy of water jet
• Head range: 300-2000m
• Components: Nozzle → Jet → Buckets → Runner → Shaft
• Energy conversion: Pressure → Velocity (nozzle) → Mechanical rotation (buckets)
• Efficiency: 88-93%

Francis Turbine (Reaction)

• Principle: Pressure and kinetic energy
• Head range: 25-350m
• Components: Spiral case → Stay vanes → Guide vanes → Runner → Draft tube
• Energy conversion: Pressure drop across runner + velocity change
• Efficiency: 90-95%

Kaplan Turbine (Reaction)

• Principle: Axial flow, adjustable blades
• Head range: 2-40m
• Components: Spiral case → Stay vanes → Guide vanes → Runner (adjustable) → Draft tube
• Energy conversion: Low head, high flow
• Efficiency: 90-93%

Losses:

• Intake and trash rack losses (0.1-0.3m)
• Headrace friction losses
• Penstock friction losses
• Turbine hydraulic losses (secondary flows, separation)
• Mechanical losses (bearings, seals)
• Generator electrical losses (copper, iron, stray)
• Transformer losses
• Draft tube losses (recovery inefficiency)
