Hydro Power Plant Diagram
Classification of hydroelectric plants.
Hydro power plant diagram. In the conventional type water is collected in the dam and its head is used for the rotation of turbine. Trol and public water supply. This resulted in upgrading of. Hydro power continued to play a major role in the expansion of electrical service around the world.
From the dam water is fed to a water turbine. Posted on november 5 2016 by admin. Hydroelectric dam 1 dam. In hydropower plant potential and kinetic energy of the water is used to rotate the turbine and hence generator to generate electricity.
The water turbine converts hydraulic energy into mechanical energy and the generator. Working principle of hydroelectric power plant. In a hydro power plant water head is created by building a dam across a river or lake. Hydroelectric power plants are generally located in hilly areas where dams can be built easily and large water reservoirs can be made.
A schematic diagram of a hydroelectric power plant is shown in figure 16. The water from the dam is led to the water turbine through the penstock and the potential energy of the elevated water is transformed into kinetic energy. There several important components of the hydroelectric power plant which we will go over in this brief and informative article. The constructional cost of a hydroelectric power plant maybe higher than that of other conventional thermal power plants because of construction of a huge dam across the flowing river.
The dam is the most important component of hydroelectric power plant. Hydro electric power plants generate from few kw to thousands of mw and are much more reliable and efficient as a renewable and clean energy source than fossil fuel power plants. Half wave rectifier circuit diagram working. The engineering cost in addition to the constructional cost is also high in a hydroelectric power plant.
Hydroelectricity is the most widely used form of renewable energy. Although a hydro electric power station simply involves the conversion of hydraulic energy into electrical energy yet it embraces many arrangements for proper working and efficiencythe schematic diagram of hydro electric plant is shown in the figure belowthe dam is constructed across a river or lake and water from the catchment area collects at the back of the dam to form a reservoira. Generation of electricity by hydropower potential energy in stored water is one of the cleanest methods of producing electric power. In 2012 hydroelectric power plants contributed about 16 of total electricity generation of the world.
