How does a solar power plant?

urgent … and please, with pictures and everything .. thanks! that's my cousin.

In first let me say that photos can not be copied in this solar thermal folder.sorry The two main types of central solar chimneys and solar thermal concentrating solar (CSP). Concentrated solar power (CSP) Solar Two, a concentration of central cylindrical solar energy plantParabolic are the most efficient and profitable CSP system design at present. They use a curved channel that reflects sunlight into a hollow tube that runs above the trough. The DIP switches in all during the day to that light remains centered on the hollow tube by the time the sun shines. A fluid flows through the tube and heated. Systems of parabolic trough full scale composed of many parallel depressions and placed in a large area of land. A solar thermal system using this principle is in effect in California in United States, called the system sees. At 330 MW, is currently operating the largest solar thermal system. SEGS used for heating oil distance: the oil passes through a heat exchanger heat to create steam that runs a steam turbine. Other systems of parabolic trough are building create steam directly into the tubes and this concept is supposed to lead to cheaper models, in general, but the concept is still in development. Power Torres (also known as 'Central Tower' core or "heart of heliostats (pylons) to use an array of plans, movable mirrors (called heliostats) to focus sunlight on a collector tower (the target). The high energy at this point of concentrated sunlight is transferred to a substance that can store heat for later use. The final heat transfer equipment has been successfully demonstrated is liquid sodium. Sodium is a metal with a capacity of high temperature, allowing the energy must be stored and extracted overnight. This energy in turn can be used to boil water for use in steam turbines. Water was first used as a heat transfer medium in the old tower of power versions (where the resulting steam used to power a turbine). This system does not generate electricity at night. Examples of power plants are the basis of heliostats 10 MWe Solar One, Solar Two, and the plant of 15 MW Solar Tres. None of these currently used for the production of active energy. In southern Africa, is planned solar power plant 4000 to 5000 heliostat mirrors, each with an area of 140 m². [3] A washing machine uses a system of general reflection, satellite dish (similar in form of satellite TV plane). It focuses all the sunlight that strikes the dish at a single point above the plate, designed to show a thermal used to trap heat and turn it into a useful form. Windshield washer, as pylons, can reach much higher temperatures due to the large concentration of light they receive. Normally the plate is coupled to a Stirling engine in a Dish-Stirling system, but also sometimes a steam engine is used. These create rotational kinetic energy can be converted into electricity through an electrical generator. [4] [5] [6]. A linear Fresnel reflector power plant uses a series of carefully planned angle mirrors to concentrate light on a linear absorption. Recent prototypes of such systems have been built in Australia (CLFR) and Belgium (Solarmundo). These systems claim to provide overall costs, allowing absorption heat element that must be shared between several mirrors. Mirrors can therefore be smaller and does not require complex drawing links to the fluid flowing from the absorber. The design can also allow the mirrors to be placed closer, allowing more efficient use of the area.
