A variety of power plants, electrical

For the production of electricity from plants generating electricity can be used . This plant has several types as described below . 1 - power plant diesel

2 - gas power plant

3 - the power plant heater

4 - combined cycle power plant 5 - Hydro-Electric Power

6 - the nuclear power plant

7 - the power plant pumped storage o

8 - solar power plant 9 - power plants, inflatable

10 - geothermal power plants,

11 - hydropower, tidal

نیروگاه diesel : in this type of power plant, the propulsion generator is a combustion engine with diesel supply . Today, from power plants, diesel as a power plant base, less used and more for an emergency, and probably the maximum load of the grid from the power plant is used . Currently, in the areas of Iran that the national network are connected are not from power plants, diesel used . The plant usually has a power 630KW up to 12000KW are .

مزایای power plant diesel include : 1 - the power plant water is not required . 2 - as emergency power in places like hospitals, universities and ... are used . 3 - in centers remote that the cost of electricity transmission from the cost of production, power plant, diesel is more used .

معایب power plant diesel include : 1 - suffering manufacturing this power plant is down . 2 - this type of power plant due to the Movement Mechanical, a lot of that in them there is life are the little . 3 - this type of power plant, the efficiency, the lower are . ( Efficiency is the ratio of the energy taken from the power plant to the energy given to the power plant ) 4 - because of the efficiency of the bottom of the plant, the cost of the electricity produced, they are high .

نیروگاه gas : power plants, gas competition, which causes rotation of the turbine can be used outdoor environment . In this plant the compressor can be used . Compressors items that are associated with the suction of ambient air into the. air compressed and the pressure it increase . Usually, to increase the efficiency of power plant etc. air intake from the vicinity of the emissions from the chimney, turbine passage up to the incoming air to the compressor, be heated . The compressed air in the compressor room, combustion can be because the fossil fuel mix can be and burns the gas by the high pressure of the room, the combustion of the contaminants as well . To make the hot gas high pressure input to the turbine, the centerpieces Wheeler to move it video, have the gas too fast, enter the turbine to be . This action by the nozzle, the beginning of the turbine can be done . Therefore, gas pressure washer and hot with the high speed of the turbine blades can be treated and cause rotation of the rotor of the turbine can be rotational motion of the rotor of the turbine also causes rotation of the generator and thus produce electricity can be . The fuel of this power plant are usually mazut, gas and fuel oil is . In Figure (2) video from a gas power plant is displayed .

مزایای gas power plant are : 1 - the power plant water is not required . 2 - early are made . ( About the construction of a gas power plant 6 months will take some time ) 3 - the power plant, speed, maneuver, have high . ( Low and high, the production of the power plant to maneuver the plant, say ) 4 - this is the power plant too early can be turned .

معایب gas power plant are : 1 – high efficiency of this power plant is down . 2 – life of this power plant is short . 3 – the cost of the electricity produced, they are high . 4 – suffering energy production the power plant is down .

نیروگاه heater : in this power plant from burning fossil fuels like oil, natural gas, mazut, etc., heat is produced, by which water inside the boiler to steam dry turns . Dry steam, i.e., heaters that is perfectly for gas, and there is no any drop of blue in it, not its temperature above 500 degrees centigrade be . The dry steam enters the turbines can be the rotors of the turbine to rotate in brings . In effect, the spin axis turbines., the generator begins to spin and makes electricity is produced . بخارهای dry out from the turbine enters the condenser and to the liquid are converted . Condenser a device that dry steam will cool to liquid conversion does . The resulting liquid by pump that back to the boiler, pumping can be . In Figure (3) the image of a power plant heater displayed .

مزایای power plant heater are : 1 – the efficiency of the power plant from the power plant, the gas is better . 2 – suffering, productive of the plant more from plants the gas is . 3 – life of the nuclear power plants, more power plants, gas is .

معایب power plants heaters are : 1 – the power plants need water . 2 – speed maneuver, this power plant is less than the power plant, the gas is . 3 – the construction of this power plant compared to power plants, gas, more time can win . 4 – the cost of electricity produced by this plant most of the plants, gas is .

نیروگاه combined cycle : this type of نیرگاه are a combination of two gas power plant and heater are . Power plants, gas some of the gases energized through the chimney turbines of the cycle of production of electricity out to be, and the same would decrease the efficiency of the power plant, the gas can be . The gas withdrawn from the flue, gas turbines, average there are a lot of and is capable of liquid water to dry steam does not convert, i.e., the same feasible that power plants, the heater can be done . So in the power plants to combined cycle of two gas power plant and heater in next to each other are . In power plants combined cycle for the activity of gas turbines from fossil fuel use, but to the activity of turbines from gases outside the lubricating of the flue gas turbines they use . This way to exchange for a certain amount of fuel, in power plants, ...
