What is Hydroelectric Energy? – Detailed Definition of the Hydropower

Definition of Hydroelectric Energy

 

Hydroelectric centrals convert the power of running water into electricity. Thanks to, the amount of energy in flowing water determine flow or speed of flowing water. Also, water flowing in a large river carries a large amount of energy. Besides, when water is dropped from a very high point, energy can be obtained. In both ways, water that taken into the pipes flow into the turbines.

Therefore, turbine with propeller that it is necessary for generating electricity provide rotation of the turbine. Also, turbines connect to generators and the turbines convert the mechanical energy to electricity energy.

 

How Hydroelectric Energy Power Plants Work?

 

What is hydroelectric power plants? Hydroelectric power plans is called as power plants that produce electricity from the motion energy of water. When the water is accumulated in dams, potential energy is given to water.

When the water that has potential energy is released from the high, the potential energy of the water convert the kinetic energy. Therefore, the water turns the turbines. When the turbines turn, the generator connected to the turbines turn and product electricity energy.

In hydroelectric power plants, the potential energy of the water is convert to the kinetic energy. Then, the kinetic energy is converted to electrical energy.

 

Hydroelectric Power Facts

 

  • To obtain energy from renewable water,
  • No greenhouse gas emissions,
  • Construction can be done with local facilities,
  • Long service life and lack of fuel costs,
  • Low operational maintenance costs,
  • Creating employment opportunities,
  • It is the most important renewable energy source in terms of revitalizing economic and social structure in rural areas.

 

How to Hydroelectric Power Plants Classified?

We can classify the hydroelectric power plants in 6 ways;

According to Storage Structures;

  • Storage (reservoir) HEPPs
  • River type (regulator) HEPPs

According to the falls

  • Low overhead HEPPs (H <10m)
  • Medium overheads (H = 10-50 m)
  • High-rated HEPPs (H> less than 50 m)

According to forces

  • Very small (micro) capacity (<100 kW)
  • Small (Mini) capacity (100-1000 kW)
  • Medium capacity (1000-10000 kW)
  • Large capacity (> 10000 kW)

According to the Status of the National Electrical System

  • Base Load HEPP
  • Puant (HEPP) Load HEPP
  • Both Base and Puant (Pik) Load HEPP

According to Dam Body Type

  • Weighted Concrete HEPP
  • Concrete Belt HEPP
  • Soil filled body hoses etc.

Central Building

  • Above Ground HEPP
  • Underground HEPP
  • Semi-Embedded or Batik HEPP
