Factors Affecting the Plant Capacity & Discipline of Engineering in a HydroPower Plant
Total Installed Capacity
- Head difference (vertical height) in water levels between two points
- Flow: the volume of water flowing through a area-cross section per unit time
No. of Units and Unit Capacity
- Accessibility and Transportation Limitations
- Availability of Technology
- Operation and Maintenance consideration
Power Developed by a Turbine
Pt = 9.81 x Q x H x η (KW)
Q = Discharge, m3/sec
H = Net Head, m
h = Efficiency of Turbine
ηtur = efficiency of turbine ( 89 % to 95 %)
ηgen = efficiency of generator (96% to 99%)
Discipline of Engineering in a HydroPower Plant
- Civil Engineering - Mechanical Engineering - Electrical Engineering
Civil Engineering further can be categories into Geological Engineering, Hydrological Engineering, Environmental Engineering and Structural Engineering.
Intake Structure and Water Conducting System
- Barrage/Dam - Diversion Structure - Intake Channel - Dislting Chamber - Tunnel - Surge & Drop Shaft - Pressure Shaft - Penstock - Powerhouse - Tail Race Structure
Mechanical Engineering aspect involve design , engineering, manufacturing, testing, selection of turbine and various equipment
Hydro-Mechanical, Power Generating Machines & Auxiliaries
- Intake Gates - Spillway Gates - Trash Rack - Disilting Valve/Gates - Penstock Protection Valve - Surge & Drop Shaft - Turbines & Auxiliaries - Main Inlet Valve - EOT Crane - Fire Protection System - Air Conditioning and Ventilation System - Cooling Water and Compressed Air System - Tail Race Gates
Electrical Engineering aspect involve design , engineering, manufacturing, testing, selection of generators, control systems, switchgear, transmission lines etc.,
Power Evacuating and Transmitting Systems
- Generators and Auxiliaries - Transformers - Control and Protection Systems - Switchyards - Circuit Breaker - Isolators - Current and Potential transformer - Communication Systems - Transmission Lines / Towers
