    Study Notes

    Hydroelectric Power Generation: How It Works and Key Components

    • Hydroelectric power is generated by converting the potential and kinetic energy of water into mechanical energy and then electrical energy.
    • The process involves storing water at high altitudes in a dam, controlling its flow through penstock to a turbine, and then to an alternator for power generation.
    • The amount of power generated depends on the height of the water reservoir, the flow rate of water, and the head (height from which the water falls).
    • A surge tank is a small reservoir located near the beginning of the penstock that serves as a supply tank to the turbine during increased load conditions and as a storage tank during reduced load conditions.
    • A trash rack is a part of the intake structure that prevents debris from entering the penstock.
    • A spillway is a passage that allows excess water to flow away from the dam to prevent overflow and maintain stability.
    • The blade-angle adjustment and water flow must be adjusted continuously to maintain a constant speed and frequency.
    • The criteria for selecting an appropriate site for a hydroelectric power plant include high water availability, convenient dam and reservoir construction, large catchment area, rocky land, minimum distance to load center, and adequate transportation facilities.
    • The potential energy of the water increases due to the height of the dam, and the high position of water in the reservoir enables it to move downwards effortlessly.
    • The turbine rotates due to the pressure of the water, and the rotation of the shaft inside the generator produces a magnetic field that is converted into electricity.
    • The total amount of power generated depends on the height of the water reservoir and the amount of water flowing through the penstock.
    • The dam should be built on a large river with abundant water throughout the year, and the controlled pressured water is fed to the turbine through controlling valves as per requirements.
