River Power Plants are two types: 1-Plants Which are fed directly by a river. D. Classification of Hydroelectric Power Plants Based on Installed Capacity: Apart from above classification, hydroelectric power plants can be classified, on the basis of installed capacity, as large, medium, small, mini, and micro hydro power plants. Hydropower plants range in size from small systems for a home or village to large projects producing electricity for utilities. Hydroelectric power plants are renewable sources of energy as the water available is self-replenishing and there are no carbon emissions in the process. 2 – Basic Block Diagram of Energy Conversion in Hydroelectric Power Plant. Let us … River Power Plants. Generally the mini, micro, and pico hydro come under the subcategory of small hydro plants. The plant can be used as a base load plant or as a peak load plant depending on the water stored in the reservoir, the rate of inflow and the system load. Run-Of-River plants that’s what they called in some countries, in this type of plants the natural and powerful flow and Elevation drop of the rivers is what it used through these kind of hydro plants to generate electricity. Low head power plants: When the head is less than 15 meters, the plant is named as Low head power plant. In this article, we’ll discuss the details and basic operations of a hydroelectric power plant. Medium head power plants: When the water ranges from 15 to 70 meters, then the power plant is known as a Medium head power plant. In this type of hydroelectric power plants the same water is utilized again and again by pumping back during the off peak hours. The classification of Hydroelectric Power Plant is done with various criteria. The sizes of hydropower plants are described below. Either by the storage capacity and the water flow or through the technologies applied. Hydroelectric power plants convert the potential energy of stored water or kinetic energy of running water into electric power.
Classification of Hydroelectric Power Plant. It uses Francis or Kaplan turbine as the prime mover. Classification based on storage By considering the availability of storage reservoirs, hydro electric power plants can be classified into power plants having storage reservoir and without storage reservoir. Grand Coulee of reservoir plants. It uses Francis Turbine. Fig. Impoundment. The most common type of hydroelectric power plant is an impoundment facility.
