Electricity is a physical term, widely expanded in technology and in terms of the amount of electrical energy, which is seen as a generator in the electric field, which is controlled by the medium. Electricity is also a commodity that participants in the wholesale market buy from generating companies and save electricity on the retail market from energy butyl companies.

Thermal power plant (TES), a power plant that generates electricity as a result of the transformation of thermal energy, which is seen when burning organic fire. The first TECs appeared in the 19th century and became more wide. In the 1970s, the 20th century, TES is the main type of electrical stations. At thermal power plants, chemical energy is converted first into mechanical, and then into electricity. The fuel for such a power plant can be wood, peat, gas, oil shale, fuel oil.

Nuclear power plant is a power plant, in which atomic energy is transformed into electricity. The energy generator at the NPP is a nuclear reactor. Heat, as seen in the reactor as a result of the Lantzug reaction, disintegrated the nuclei of some important elements, then just like that, as in the greatest thermal power plants, is transformed into electricity. On the basis of TEC, which works on organic fire, AES works on nuclear fire.

Close to 80% of the growth of GDP (gross domestic product) of the rozvinenye krai is available from additional technical innovations, more important than that is due to electricity generation. Everything is new in the industry, the agricultural state will try to come to us as a start to new developments in the various galleries of science. Today's sustainability is impossible to manifest without electrification of virobnic activity. Already, for example, in the 80s, 1/3 of the energy reduction in the world was observed in the electric energy. On the cob of the coming century, a part can be increased to 1/2. Such an increase in the supply of electricity to us is tied to an increase in the supply of electricity.

With this post, the problem of effective victorization is energy. When transmitting electricity, large windmills, from the vibrator to a slowdown, spend heat on the transmission lines, increasing in proportion to the square of the struma, tobto. If the strum is subdued, then the heat will be spent four times more. That’s why it’s bad, schob strum at the lines of buv maly. For whom to increase the voltage of the gear lines. Electricity is transmitted by lines, where the voltage is hundreds of thousands of volts. There was a place where the energy was taken from the line transmissions, and the voltage for the auxiliary step-down transformer was brought up to a few thousand volts. At the very place at the substations, the voltage drops to 220 volts.

Our country occupies a large territory, maybe 12 time zones. And it means that although in some regions the reduction of electricity is maximum, then in others the working day has already ended and the reduction is decreasing. For a rational vikoristannya elektroenergії voroblyuvanym stink power plants are united in the electric power system of okremi districts: the European part, Siberia, the Urals, the Far Skhod and іn. Thus, the association allows the efficient generation of electric power to the benefit of the work of other power plants. Differently different energy systems are united into a single energy system of Russia.

Presentation on the topic: "Virobnitstvo and transmission of electricity" Pupil 11 and class SBOU ZOSh No. 1465 Startsova Tetyana. Teacher: Kruglova Larisa Yuriivna
Generation of electricity Electricity is generated at power plants. There are three main types of power plants: Nuclear power plants (AES) Hydroelectric power plants (HPP) Thermal power plants, or thermal power plants (CHP)
Atomoni Elektrostannitsky Atomona Elektronetsiya (aes) - nuclear installation for the vibrors of the energії in the tasks of the regimes of the same time, the roshtashovs in the interjes of the Teritor project, on the Yakiy, the nuclear reactor (reactor) is not the same, the complex of the non -core, the remote control, the outbreak necessary practitioners
Robotic principle
The small diagram shows a diagram of a robotic nuclear power plant with a double-loop water-cooled power reactor. The energy that is seen in the active zone of the reactor is transferred to the heat carrier of the first circuit. They let the heat-carrier go to the heat exchanger (steam generator), de-heat the water to another circuit until it boils. Otriman when the steam comes from the turbine, which wraps the power generators. At the exit from the turbines, steam comes from the condenser, where it cools down with a great amount of water that comes from the reservoir. The compensator for the vice is to be made with a folding and bulky design, as to serve for vibrating the vise in the circuit of the reactor for hours of operation, which is blamed for the expansion of the thermal expansion of the heat transfer. The pressure at the 1st circuit can reach 160 atm (VVER-1000).
Krіm vodi, in different reactors in the capacity of heat transfer can also be smelted metals: sodium, lead, eutectic alloy of lead with bismuth and in. The use of rare metal heat transfer fluids allows the design of the core shell of the reactor to be atmospheric, if the compensator is used. The total number of circuits can be changed for different reactors, the diagram in the figure is for VVER type reactors (Water-Water Power Reactor). Reactors of the RBMK type (Reactor of the Great Intensity of the Channel type) vicorist one water circuit, reactors on liquid neutrons - two sodium and one water circuit, promising designs of reactor plants SVBR-100 and BREST allow a double-circuit scheme, with important heat transfer from the first circuit and water. .
Generation of electricity by world leaders in the generation of nuclear electricity: USA (836.63 billion kW/yr), 104 nuclear reactors (20% of electricity generated) France (439.73 billion kW/yr) (263.83 billion kW/yr/rec), Russia (177.39 bln kW/yr/rec), Korea (142.94 bln kW/yr/rec) Nimechchina (140.53 bln kW/yr/rec). The world has 436 nuclear power reactors with a heat output of 371.923 GW, the Russian company TVEL supplies fuel for 73 of them (17% of the light market)
Hydroelectric power station (HES) - a power station, like a dzherelo energy of vicorist energy of the water flow. Hydroelectric power stations will sound on the rivers, sporadzhuyu rowing and watersheds. For the efficient generation of electricity at HPPs, two main factors are necessary: guaranteed water supply to the rivers and the possibility of large rivers, to absorb the hydropower of the canyon-like landscape.
Robotic principle
Lance of hydrotechnical spores is the provision of the necessary pressure of water to get on the blades of hydro turbines, to drive generators, to generate electricity. The necessary pressure of the water is settled for the help of rowing, and as a result of the concentration of the river in the singing place, or the derivation - the natural stream of water. In certain vipadkahs, for the removal of the necessary pressure, drive the vicorist at once and rowing and derivation. Without a hitch at the very house of the hydroelectric power station, all the energy installations are being installed. Zalezhno vіd prichennya vono maє svіy svіy podіl. At the engine room, there are installed hydroelectric units, which without interruption transform the energy of the stream of water into electrical energy.
Hydroelectric stations operate in the fallow in the presence of pressure, which vibrate: intensify - vibrate at 25 MW and more; medium - up to 25 MW; small hydroelectric power plants - up to 5 MW. Also, the stench stagnates fallow in the maximum water pressure: high water pressure - over 60 m; middle napirnі - vіd 25 m; low pressure - from 3 to 25 m.

Transmission of electric power Transmission of electric energy from electric stations to the rescue is carried out by electric barriers. Elektromezhna Mirenarism is a derogene and monk sector of the Elektroenertei: Svozhozhach can do it, who has a Kupuvati Elekenergius (Tobto Energozbutov), Energozbutov’s compani, they can see the Oppotovikhi (Vibrony Elekenerg). it is impossible to choose an electrical company. From the technical point of view, the electric line, the supply of power transmission lines (LEP) and transformers, which are located at the substations.
Power transmission lines are a metal conductor, as a way to pass an electric jet. At the given hour, a change of strum is practically everywhere victorious. Electricity supply in the most important way - three-phase, therefore, the power transmission line, as a rule, consists of three phases, the skin of which can include a wire wire.
Power transmission lines are divided into 2 types:
Povіtryany LEP suspended above the surface of the earth on a safe height on special sporuds, called supports. As a rule, there is no surface insulation on the red line; insulation is fixed to supports at the points. On redundant lines there are systems for lightning protection. The main advantage of the power transmission lines is the cheapness of the cable lines. Also, the repairability is better (especially in the case of parallel lines with collectorless CLs): it is not necessary to carry out earthworks to replace the dart, there will be no difficulty in visual inspection of the lines. However, there are a number of nedolіkіv near the covered LEPs: a wide smuga vіchuchennya: in the outskirts of the LEP it is fenced to put whether or not to plant a tree; when the line is passed through the wood of the tree along the entire width of the smug, the smog is cut off; innocence from the windy inflow, for example, falling trees on the line and stealing darts; not respecting the lightning striker on the outbuilding, the broken lines also suffer from the blows of the glare. Through strife, on one redundant line, two lancets often possess: the main one and the reserve one; aesthetic unpretentiousness; This is one of the reasons for the practically ubiquitous transition to the cable method of electricity transmission at the boundaries of the city.
Cable lines (CL) are carried out under the ground. Electric cables change the design, but you can also show the lighting elements. The core cable had three strum conductors (for the number of phases). Cables can be made like sound, so they can be used as insulation. Sound like an insulator, transformer oil in a rare look, or oiling paper. Strumoprovidna cable core, as a rule, is protected by steel armor. On the outer side, the cable is covered with bitumen. There are collectors and non-collector cable lines. At the first fall, the cable is laid at underground concrete channels - collectors. Through singing gaps on the lines, you can get out on the surface at the sight of hatches - for the transparency of the penetration of repair teams at the collector. Collectorless cable lines are laid without a middle at the ground.
Collector-free lines are quite cheap for collectors in everyday life, prote їх exploitation is more costly in connection with the inaccessibility of the cable. The main line of cable power transmission lines (along with repeaters) is the daytime of a wide range of traffic. For the mind to file a deep mortgage, the difference (among those living) can be directly over the collector line. In the case of a non-collector mortgage, life is possible with an uninterrupted proximity to the line. The cable lines don't tell the miserable landscape with their eyes, the stench is richer for the protection of the outside air. Up to a few cable lines of power transmission, you can see the high variability of everyday life and further exploitation: in the case of a collector-free laying, there is a variability of a running meter of a cable line in a difference, a lower variance of a cable line on that cable. Cable lines are less accessible for visual observation (and in times of collectorless laying, they are not available), which is also a significant operational shortfall.

But science is not only victorious electricity in its theoretical and experimental fields, scientific ideas are gradually blamed on the traditional theory of physics, which is related to the adoption of the transmission of electricity. Vcheni, for example, are trying to create electric generators without particles that wrap around. In the best electric motors, a constant stream is brought to the rotor, so that the “magnetic force” winkles.

Such an increase in the supply of electricity to us is tied to an increase in the supply of electricity. The main part of industrial enterprises works on electric energy. The high level of electric power is typical for such energy-consuming galuses, like metallurgy, aluminum and machine-building industry. Transport is also a great helper. The Daedals of more transshipment lines will be converted to electric traction. Mayzhe all villages and villages receive electricity from state-owned power plants for industrial and utility needs.
