History and ideas of development of electrical and electronics science

The purpose, tasks and development of electricity in Uzbekistan.
Electrical engineering is a science of electricity generation, practical use of electric and magnetic phenomena. This science is the production of electricity

solves all issues related to its transfer and use.

Electricity is a universal form of energy that can fulfill all the tasks assigned to it;

- teaches the structure and principle of operation of electric power generating devices;

- teaches the structure and principle of operation of electric machines working on electricity;

- teaches the fields of electrical energy management and construction and use of protective equipment;

-allows to fully automate production.

The 20th century is considered a decisive period in the field of energy and electrification. Because this period is closely related to the emergence of radio and semiconductor technology, the discovery of television, the development of automation and telemechanics, the unprecedented growth of microelectronics and energy, the discovery and development of the integrated microcircuit and atomic energy.

In general, the achievements of electrical engineering are widely used in all sectors of the mining industry. Electrical engineering is a branch of science and technology that teaches the laws of generation and change of electric and magnetic energies in electric circuits and electromagnetic fields. The improvement of devices using electric energy ensures that technological processes are carried out at such a speed and accuracy that a person cannot perceive and control them with his senses. This, in turn, causes automation in production processes. It is impossible to imagine the progress achieved especially in the field of mechanization and automation of agriculture without electricity.

The share of electric energy in the gross industrial product of the Republic of Uzbekistan exceeds 10%. The integration of different electric power generating power stations into one high-voltage overhead line and controlled centrally is called an electric power system. 85-90% of the electricity produced in the country is produced in thermal power stations. HPPs are power plants that can be built quickly and cheaply. With the technical capabilities available today, it is possible to build HPPs with a capacity of 6 million kWh. It is considered more important for the economy of the country that the price of electricity is cheap. The price of this energy first of all depends on the costs of extracting and transporting the fuel used for the production of this energy. Therefore, it is important to take these factors into account when building new power stations. If the cost of fuel transportation is higher than the cost of electricity transmission, then it is better to relocate the power plant. The distance of electric energy transmission is increasing year by year with the growth of scientific and technical progress. Transmission of electricity through wires is one of its advantages. The use of electric energy in all spheres of the economy is considered the second most important advantage of this energy. The possibility of wide use of local fuels is its third advantage, and finally, the ability to produce electricity in powerful power stations, that is, the ability to generate several million kilowatt hours of energy in one place is its next advantage. and they are called GRES. GRES of Sirdarya, Tashkent, New Angren, Navoiy, Takhyatosh, Angren GRES are working in our country. Only Syrdaryo GRES produces 13 billion kWh of electricity per year
