1. INTRODUCTION

One of the most broadly used renewable source of energy for generating electricity on enormous scale is hydropower.

Hydropower is a tremendously flexible technology for power generation. Hydro reservoirs provide built-in energy storage, and the firm response period of hydropower enables it to be used to optimise electricity production across grids, meeting sudden fluctuations in demands.

The power acquired from river or ocean water is called as hydropower.

Hydroelectric power, or electricity, is mostly electrical energy that has been generated using natural forces such as gravity or flowing water. It’s generally produced by dams, since dam can store and direct large volumes of water. Hydroelectric power is becoming increasingly popular.

Hydropower is the renewable source of energy since water is available in large amounts from rain, rivers, and oceans and this is will be available for limitless time to come.

According to the World Energy Council, about33 % of the planet water resources have been developed.

More than 90 % of the available hydropower potential have already

been technologically advanced in France, Switzerland, and Austria.

 65 to 90 % – in Japan, Germany, and Sweden,

 45 to 65 % – in the USA, Canada, Brazil and Spain,

 20-45 % – in China, India, and Argentina.

2. TYPES

i. Water wheels

ii. Hydro power plants

iii. Wave energy from oceans

iv. Tidal energy

v. Dam less hydro power

 Based on Quantity of Water Available

 Run-of river hydropower plants with pond:

These are hydro power plants that utilize the watercourse flow as it comes, without any storage provided. Run-of-the-river power plants may have no water storage at all or a restricted quantity of storage, in which case the storage reservoir is referred to as poundage. A plant without poundage has no water storage and is, therefore, subject to seasonal river flows. Thus, the plant will operate as an intermittent energy source while a plant with poundage can regulate the water flow at all times and can serve as a peaking power plant or base load power plant.

 Storage hydroelectric power plants:

Hydropower plants with storage are supplied with water from large storage reservoir that have been established by constructing dams through rivers.  Assured flow for hydro power generation is more certain for the storage systems than the run-of-river systems. Figure-pumped storage hydropower plant.

 Based on the Head of Water Available

 Low head hydroelectric power plants:

Low head hydro power applications use river current flows of 30 meters or a lesser amount to produce energy. These applications do not need to dam or hold water to form hydraulic head, the head is only a few meters. Using the current of a river or the naturally arising tidal flow to create electricity may afford a renewable energy source that will have a minimal effect on the environment.

 Medium head hydroelectric power plants:

The hydro power plants in which the working head of water is between 30 meters but 300 meters are called medium head hydroelectric power plants. These hydroelectric power plant are generally situated in the mountainous sections where the rivers flows at great heights, thus obtaining the high head of the water in dam becomes possible.

 High head hydroelectric power plants:

A power station operating under heads above 300m. A head of 200m/250m is measured as the limit between medium and high head power stations.

 Based on the Nature of Load

 Base load hydroelectric power plants:

The base load type of hydroelectric power plants produce power frequently irrespective of the total load in the national grid. They keep on producing power during the day and all the times of the year. They will halt producing power only during breakdown maintenance.

 Peak load hydroelectric power plants:

Most of the usual power requirements are satisfied by the base load hydroelectric power plants. However, during night times the necessity of power turn out to be very high; it is called peak load period. During peak load periods small power plants are started that add to the overall power generated in the grid by base load plants. The peak load plants are not run nonstop since the price of production of power from them is high.

3. PRINCIPLE

 WATER CYCLE

The unbroken cycle in which water changes from water vapour in the atmosphere to liquid water through condensation and precipitation and then back to water vapour through evaporation, transpiration, and respiration. This is a natural course that occurs. This natural cycle is very important living organism present on the earth.

 WATER CYCLE IN NATURE

 Water surface evaporation

 Precipitation of clouds

 Surface run-off

 Collected back to the oceans

 Sublimation

 Advection

4. STAGES

 Hydroelectric dam

There is potential energy deposited in a water reservoir at the rear end of dam. It is changed into kinetic energy when the water begins to flow down the penstock, from the dam. This kinetic energy is used to turn a turbine.

 Generator

The subsiding water strikes a series of blades attached around a shaft which transforms kinetic energy to mechanical energy, and makes the turbine to rotate. The shaft is connected to a generator, so that when the turbine rotates, the generator is driven. The generator changes the turbine\'s mechanical energy into electric energy.

 Step-up transformer

Voltage is the force that makes electricity flow. Generators usually fabricated electricity with a low voltage. For the transmission lines to transmit the electricity efficiently over long distances, the low generator voltage is amplified to a higher transmission voltage by a step-up transformer.

 Grid high voltage transmission lines

Grid transmission lines, usually supported by giant metal towers, carrying high voltage electricity to long distances.

 Terminal Station

Terminal stations control power run on grid transmission lines and decrease the grid voltage to sub transmission voltage.

 Sub transmission lines

Sub transmission lines stream power from terminal stations to huge industrial customers or distribution substations.

 How it is used by the customer

Electric energy can be traded at transmission voltage to users of enormous amounts who own and function their own substations. Most customers, however, are incapable to accept energy at transmission voltage, and necessitate that it be stepped down in a transformer.

 Distribution substation

A distribution substation is a system of transformers, meters, and control and defensive devices. At a substation, transmission voltage is lowered to lower voltages for distribution to domestic, commercial, and small industrial customers.

5. COMPONENT

 DAM: -

A dam is a blockade that holds water or underground streams. Reservoirs formed by dams not only holds floods but also provide water for irrigation, human consumption, industrial use, aquaculture and etc. Hydropower is frequently used in combination with dams to generate electricity. A dam can also be used to gather water or for storage of water which can be uniformly distributed between locations. Dams generally assist to the primary purpose of holding water.
