Study Notes
Hydropower Generation
- Hydropower generation is based on the potential energy of water at height, which can be harnessed from lakes, reservoirs, and rivers.
- The potential energy of water is referred to as water power, and the height is referred to as the head.
Characteristics of Hydropower Energy
- Hydropower energy is a clean, renewable, and reliable energy source.
- It serves national environmental and energy policy objectives.
Hydraulic Potential and Hydraulic Resource
- Hydraulic potential is the combination of possible flow and the distribution of gradients.
- Hydraulic resource is the fraction of hydraulic potential that is still accessible after considering economic factors.
Hydropower Generation Process
- Hydropower energy is derived from falling water, either from rivers and streams flowing downhill to the sea or to lakes and dams.
- The force of gravity drives the movement of water, which releases kinetic energy through friction as it flows over rocks and sediments on the riverbed.
- By harnessing the kinetic energy, hydroelectricity can be generated using turbines driven by the force of flowing water.
Factors Affecting Kinetic Energy
- The amount of kinetic energy stored in moving water is directly related to the volume of water and the velocity due to pressure with which the water flows.
Classification of Hydropower Generation Systems
- Hydropower Generation Systems are mainly classified into two types: conventional and pumped storage systems.
