Distributed Collector Solar Thermal Electric Power Plant

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.

Distributed collector solar thermal electric power plant.

Solar thermal collectors are classified by the united states energy information administration as low medium or high temperature collectors. During the 18th century solar furnaces capable of melting iron copper and other metals were constructed of polished iron glass lenses and mirrors. The selected systems include. 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.

Kalogirou in solar energy engineering 2009. Solar thermal collectors are either non concentrating or concentrating. The solar collector outlet temperature and plant power output are controlled. 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.

Storage enables constant power output despite variable solar radiation. 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. The efficiency of a solar thermal power plant is the product of the collector efficiency field efficiency and steam cycle efficiency. Medium temperature collectors are also usually flat plates but are used for heating water or air for residential and commercial use.

A photovoltaic system also pv system or solar power system is a power system designed to supply usable solar power by means of photovoltaics it consists of an arrangement of several components including solar panels to absorb and convert sunlight into electricity a solar inverter to convert the output from direct to alternating current as well as mounting cabling and other electrical. Storage increases the solar share by 47. Low temperature collectors are generally unglazed and used to heat swimming pools or to heat ventilation air. 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.

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. They can cater the load demand perfectly and work as base load power.

Though solar pv generates cheaper intermittent power during the day light time it needs the support of sustainable power generation sources to provide round the clock power. 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.
