Distributed Collector Solar Thermal Electric Power Plant

The collector efficiency depends on the angle of incidence of the sunlight and the temperature in the absorber tube and can reach values up to 75.

Distributed collector solar thermal electric power plant.

Consideration is given to the selection of operating temperature type and degree of solar energy concentration and thermal engine and organic working fluid and to system. The selected systems include. 1 fixed orientation collectors with concentrating reflectors and vacuum tube absorbers 2 one axis tracking linear concentrator including parabolic trough and variable. Storage increases the solar share by 47.

During the 18th century solar furnaces capable of melting iron copper and other metals were constructed of polished iron glass lenses and mirrors. The solar collector outlet temperature and plant power output are controlled. Kalogirou in solar energy engineering 2009. Low temperature collectors are generally unglazed and used to heat swimming pools or to heat ventilation air.

A systems level model is used to evaluate a solar thermal power plant with thermal storage. Solar thermal power plants may also be hybrid systems that use. Solar thermal hybrid systems. A solar thermal collector collects heat by absorbing sunlight the term solar collector commonly refers to a device for solar hot water heating but may refer to large power generating installations such as solar parabolic troughs and solar towers or non water heating devices such as solar air heaters.

Solar thermal power systems may also have a thermal energy storage system component that allows the solar collector system to heat an energy storage system during the day and the heat from the storage system is used to produce electricity in the evening or during cloudy weather. Solar thermal collectors are classified by the united states energy information administration as low medium or high temperature collectors. The efficiency of a solar thermal power plant is the product of the collector efficiency field efficiency and steam cycle efficiency. Solar thermal plants with thermal storage are clean sustainable power generation to supply electricity round the clock.

Medium temperature collectors are also usually flat plates but are used for heating water or air for residential and commercial use. Storage enables constant power output despite variable solar radiation. A preliminary comparative evaluation of distributed collector solar thermal power plants was undertaken by projecting power plant economics of selected systems to the 1990 to 2000 time frame. The design parameters for a medium sized 100 1000 kwe concentrating collector solar thermal power station intended to provide energy with little maintenance and at competitive costs in remote regions are discussed.

As was seen in chapter 1 section 1 5 chapter 1 section 1 5 solar thermal power systems were among the very first applications of solar energy. They can cater the load demand perfectly and work as base load power.
