Hydraulic energy

Hydropower is a source of renewable and alternative energy. This renewable energy exploits the transformation of gravitational potential energy, possessed by a certain mass of water at a certain elevation, in kinetic energy to overcome a certain difference in height. The mechanical energy obtained can be used directly to rotate the shaft of a turbine or in some application or machine that works in hydraulic power. The most common is to use this kinetic energy to generate electrical energy. In this case, we talk about hydroelectric power.

In hydroelectric power, the kinetic energy is…

Fracking

Fracking

Hydraulic fracturing or geotechnical fracking is the exploitation of the pressure of a fluid, typically water, to create and then propagate a fracture in a layer of rock in the subsoil. Fracking is carried out after a drilling in a rock formation containing hydrocarbons (oil or natural gas). The objective is to increase the permeability. Improving permeability improves the production of oil or gas contained in the subsoil and increases its recovery rate.

Hydraulic fractures in rocks can be both natural and created by humans; they are created and enlarged by the pressure of the fluid…

Pelton turbine

Pelton turbine

The Pelton turbine is a type of turbine used in the hydraulic energy industry within the field of renewable energy.

A Pelton turbine is a hydraulic turbine of the impulse type used in hydroelectric power plants with high vertical height. It was Invent to by Lester Allan Pelton in the 1870s and Amend significantly by other inventors beyond late 1800. The Pelton turbine is a further development of traditional water wheel. The Pelton turbine transforms the hydraulic energy into the impulse of one or more jets…

Mini-hydraulic power station

Mini-hydraulic power station

A mini-hydraulic power plant is a power plant that uses hydraulic energy for the production of electricity. They are characterized by the fact of having a reduced installed power. Its small size implies the use of structures of much smaller size than a normal dam. These mini-hydraulic plants are safer, thanks to the smaller volume of water in the basin, and which also have a lower environmental impact and landscape.

There is no globally accepted limit for which a hydroelectric plant is defined as mini-hydraulic. According to the ESHA (European Association of Small Hydroelectric Power…

Francis turbine

Francis turbine

The Francis turbine is a hydraulic turbine used in hydraulic power installations with a considerable height of fall.

The Francis turbine is a type of hydraulic turbine built by British-American engineer James Bicheno Francis. The function of the Francis turbine is mainly to generate electricity with the help of a generator. Francis turbines have a high utilization capacity of more than 90% and a wide range of activities compared to the height (building drop) of the fluid flowing through the turbine. This is particularly emphasized in water where it achieves optimum performance in a building…

Hydraulic turbines

Hydraulic turbines

A turbine is a turbomachine that converts the energy of flow of a fluid (liquid or gas) into mechanical energy by means of a system of rotating blades. This mechanical energy can be used to power another machine or an electric generator.

The turbine name was proposed by Claude Burdin during an engineering contest in 1828. This name comes from the Latin turbine, which means Foucault current.

A simple turbine consists of a single rotor with vanes, which provide exchange of energy with the flow. The first examples of turbines are wind turbines and water mills (wind power and hydropower).

Hydroelectric power

Hydroelectric power

Hydropower is the electric power produced in a hydroelectric power station from a current, vertical or horizontal, of a river. In other words, it is electricity (electrical energy) obtained from hydraulic energy (mechanical energy of water in movement of rivers, lakes and marshes).

The difference between hydroelectric and hydraulic energy is that hydraulic energy can be used to generate electrical energy but also to obtain energy of another type, for example, mechanical energy. While hydropower refers only to the use of hydropower to obtain electric power or electricity.

The technical…

Rated voltage

Rated voltage

In electricity, the rated voltage of an electrical device is the voltage that must not be exceeded in normal operation. The nominal adjective is because that tension usually serves to characterize the device, to name it. The nominal value indicates the theoretical or ideal value of anything that can be quantified, as opposed to the real value, which is what is obtained in a given measurement.

Another definition of rated voltage: The rated voltage is the specific potential difference for which a device or installation is designed.

As it is a nominal value it implies that the voltage…

Renewable energy

Renewable energy

Renewable energy is that energy that comes from practically inexhaustible natural sources. They are considered inexhaustible either because of the large amount of energy they contain or because they can be regenerated naturally.

Among the main advantages of renewable energies we highlight the following:

Renewable energies are respectful with the environment and do not pollute.In this sense, they are safer and pose fewer health risks than other sources of non-renewable energy.

In most cases they are simple to dismantle and it is not necessary to guard their waste, as it…

Kaplan turbine

Kaplan turbine

The Kaplan turbine is a hydraulic jet turbine that uses small gradients, up to a few tens of meters, but with large flows, from 200/300 m³ / s. It is therefore a type of turbine used in hydraulic energy, a type of renewable energy.

The Kaplan turbine was invented in 1913 by the Austrian professor Viktor Kaplan.

Constructively, this type of hydraulic turbine is a propeller, where the blades can be oriented, since the water flow varies, which allows the performance to remain high up to flows of 20-30% of the nominal flow. In general, the turbine is equipped with fixed stator…

Advantages and disadvantages of hydraulic power

Advantages and disadvantages of hydraulic power

Hydropower is a source of renewable energy that uses water to generate energy. Normally, it uses the potential energy of water at a certain height to generate turbines and with them, electricity.

The mechanism of operation is to take advantage of the potential energy of water at a certain height, it is dropped to convert this energy into kinetic energy. With the kinetic energy of water a turbine that is connected to an electric generator is activated.

Generally, the installations responsible for hydroelectric production are hydroelectric power plants. Usually these facilities…

Components of a solar thermal installation

Components of a solar thermal installation

The function of a solar thermal installation is to take advantage of solar energy to generate heat. The solar panels of these facilities capture the heat of the solar radiation that falls on them to heat a fluid. The different ways to take advantage of this hot fluid allows us to use this type of renewable energy in multiple applications.

A solar thermal installation consists of:

  • Solar collectors
  • Primary and secondary circuits
  • Heat exchanger
  • Accumulator, pumps
  • Glass of expansion
  • Pipelines
  • Main control panel.

Hydroelectric power station

Hydroelectric power station

A hydroelectric power plant is a set of hydraulic engineering works located in a certain succession, together with a series of suitable machines. The objective of a hydroelectric power plant is to obtain electricity from the potential energy of moving bodies of water. This is what is called hydraulic energy.

The energy produced by hydroelectric plants must be classified in all aspects as renewable energy because, at least in theory, water can be reused endlessly for the same purpose without undergoing a purification process. The concept of renewability is subordinated to the constancy…
