# Hydroelectric

The renewable energy facility will consist of 3 different parts.

The hydroelectric power plant contains gravitational potential energy of the water accumulated in the dam. When water falls from a certain height, according to the principle of energy conversion, Gravitational Potential Energy is first converted into kinetic energy and then into potential electrical energy by means of the rotation of the generator motor connected to the turbine wheel. This is called a hydroelectric power plant, which is classified as renewable energy. Hydroelectric power is a type of energy that has widespread use. Hydroelectric power plants are special structures, and the units and elements of a regulator-type hydroelectric power plant are usually; regulator, sedimentation pool, transmission channel, tunnel, loading pool, forced pipe, unit, tail water channel, energy transmission line, transportation roads, etc.

The water gained potential by the structures built in front of the water is sent to the turbines through the channel or directly through the forced pipes according to the type of power plant. Electricity is produced by turning the turbine wheel of the water and the rotor of the generator connected to it. Hydroelectric power plants are facilities established to produce energy. It is ensured that the water that has reached a certain level, either artificially or naturally, is transmitted to the lower turbines. water that is rapidly hitting the lower parts of the turbine impellers; in this way, it ensures the rotation of the turbine shaft. With this mechanism, the operation of the generator is revealed, and the production of electrical energy is carried out.

Expression of power potential for a hydroelectric power plant,

P = p x H x η x Q x g

(P=Power, ρ=Density, η=Efficiency percent energy transferred. Q=Flow, g=Acceleration of gravity)

The work of 1 ton of water in a dam with a net drop of 100 m is equal to

P = 1000*9.8*100 = 980,000 N-m = 980 000 joule(j)

Hydroelectric power plants can be classified according to their storage structures, according to their dreams, according to their installed power, according to the type of dam body, etc. According to the head: low-head power plants smaller than 15 m, medium-head power plants 15-50 m, high-head power plants larger than 50 m. According to the character of the energy they produce, base power plants are classified as peak power plants. According to their capacity: low capacity 100-999 kW, medium capacity 1000-9999 kW, high capacity 10000 kW and above are classified as power plants. According to their construction: underground, semi-buried or submerged, above-ground power plants. According to the characteristics of the water: river, canal (with regulator), dam, pumping power plants. The turbine type is selected according to the decrease in the power plant and the water flow rate to the turbine. The choice of generator to be used for electricity generation is determined according to the power of the power plant planned to be installed and the turbine speed to be used.

Hydroelectric power has a number of technical advantages compared to other renewable energy sources. The first is that it is a safe energy. Another advantage is that the energy obtained can be stored and used when needed. Storage HEPPs make this possible. However, it is also a great advantage that HEPPs with low capacity can be converted into high-capacity systems in just a few seconds. Although the initial investment cost is high, it has advantages such as meeting it in a short time and maintenance and repair costs are very low.

Since hydraulic energy is renewable, its environmental importance is great. In addition, since there is no raw material consumption in hydroelectric energy, the operating costs are quite low compared to fossil fuel thermal power plants. In addition, energy production in hydraulic power plants is cleaner than in power plants, which leave a large amount of harmful waste into the atmosphere. Compared to other power generation systems, hydroelectric power plants have the least operating cost, the longest operating life and the highest efficiency.

Since there is no waste in hydroelectric power plants, there is no environmental pollution in the regions where they are located. At the same time, HEPPs are renewable, clean structures that provide high efficiency. HEPPs are long-lasting and the investments made are paid in a short time. The fact that the construction cost is low, does not cause environmental pollution and most importantly is a domestic resource makes HEPPs an important resource.

One of the biggest advantages for the Evadore Ecosystem is that the unit price of the energy produced is affordable. A large part of the investments made for the hydroelectric power plant consists of Eva Chain transaction fees and contributes to the development of Evadore. It is an important resource that reduces processing fees thanks to its affordable cost since hydraulic energy is renewable, it is of great environmental importance. In addition, since there is no raw material consumption in hydroelectric energy, the operating costs are quite low compared to fossil fuel thermal power plants. In addition, energy production in hydraulic power plants is cleaner than in power plants, which leave a large amount of harmful waste into the atmosphere.
