Tidal Power Plant – Types and Working Principle: Introduction to tidal power plant – Gravitational force between the moon, the sun and the earth causes the rhythmic rising and lowering of ocean water, around the world that results in tide waves. The moon exerts more force (twice) on the tides as the sun exerts, due …
Wind Energy and Wind Power Plant: Wind is a form of solar energy. It is caused by the uneven heating of the atmosphere by the sun due to the irregularities of the earth’s surface, and rotation of the earth. Wind flow patterns are modified by the earth’s terrain, bodies of water, and vegetative cover. The …
Turgo Turbine Working Principle: The Turgo turbine is an impulse water turbine designed for medium head applications. Operational Turgo Turbines achieve efficiencies of about 87%. It works with net heads between 15 and 300 m. It is a modification of the Pelton wheel, the Turgo Turbine has some advantages over Francis and Pelton designs for …
Micro Hydel Power Plant – Components and its Workings: Micro Hydel Power Plant was the most common way of electricity generating in the early 20th century. The first commercial use of hydroelectric power to produce electricity was a waterwheel on the Fox River in Wisconsin in 1882 that supplied power for lighting to two paper …

Selection of Hydraulic Turbines: It is very important to select the type of Hydraulic turbine which will give maximum possible efficiency. The Selection of Hydraulic Turbines always match specific conditions under which it has to operate and attain maximum possible efficiency. The choice of Selection of Hydraulic Turbines depends upon given head and discharge at …
Oil Pressure Governor and its Working Principle: The primary purpose of a governor for a hydro electric unit is to control the speed and loading of the unit. It is accomplished by controlling the flow of water through turbine. In Normal conditions the turbine should run at constant speed irrespective to changes in load. This …
Kaplan Turbine Working Principle: Kaplan Turbine Working Principle – The water from the scroll casing flows over the guide vanes. It is deflected through an angle of 90° in between guide vanes and runner. Then it flows axially into the runner. The blades are shaped such that water flows axially in the runner. It can …
Classification of Hydraulic Turbines: The important classification of hydraulic turbines are: 1. According to the type of energy Impulse turbine, and Reaction turbine If the energy available at the inlet of the turbine is only kinetic energy, the turbine is known as impulse turbine eg. Pelton wheel. An impulse turbine operates under atmospheric pressure throughout …
Site Selection for Hydroelectric Power Plant: The Site Selection for Hydroelectric Power Plant includes several structures like dam, conduits intakes, surge tank, power house and many others. It requires several investigation and study to determine the most economical solution. The following factors must be considered while on site selection for hydroelectric power plant. Water availability …
Components of Hydroelectric Power Plant: Components of Hydroelectric Power Plant (or) Hydel power plant are Reservoir Dam Trash rack Surge tank Fore bay Pen stock Spill way Power house Draft tube Reservoir: The main purpose of a reservoir is to store the water during rainy season and to supply the same during dry season. Reservoir …
