Solar Central Receiver System Pdf

Central receiver systems central receivers or power towers use thousands of individual sun tracking mir rors called heliostats to reflect solar energy onto a receiver located on top of a tall tower. Although the central receiver systems are originated for power generation through the utilization of solar energy these systems may also be employed in other fields.

The worlds current largest solar thermal power system is a power tower system named ivanpah.

Solar central receiver system pdf. This system consists of 1818 heliostats each with a reflective area of 399 m2 430 ft2 covering 291000 m2 72 acres of land. Significant potential for developing large scale central receiver solar plants is hence attributed to deserts and flat arid areas which have plenty of sunshine and lower land value with respect to other applications and industries. Reducing the cost of the heliostat can substantially reduce the generation costs as determined by sam but the key is determining the conditions that make this possible.

Another approach to achieving the concentrated sunlight needed for solar thermal power plants is based on a system of computer controlled mirrors called heliostats which bounce sunlight onto a receiver mounted on top of a tower see image end of article. Using nrels system advisor model sam with the 211m 2 as a constant value the generation cost for a solar central receiver system with 75 capacity factor is 132 centskwh. Central receiver technology for generating electricity has been demonstrated in the solar one pilot power plant at barstow california.

The solar central receiver power plant. Solar central receiver systems. Solar central receiver scr systems are consider ed to be a promising technology for solar radiation collection and conversion into high t emperature thermal energy for electricity production.

Molten salt central receiver system for power generation using a reheat steam cycle. The concentrated energy reflected by the heliostats enables the heating of molten salt to temperatures in excess of 565oc. The receiver collects the suns heat in a heat transfer fluid molten salt that flows through the receiver.

Thousands of mirrors known as heliostats track the sun on two axes and concentrate the solar energy onto the molten salt central receiver mscr located in the centre of the heliostat field at the top of a tower. Central receiver systems that use large heliostat fields and solar receivers located on top of a tower are now in the position to deploy the first generation of grid connected commercial plants. 13 objective the objective of this thesis is to provide a method for sizing and designing a small scale solar central receiver power plant system located in san luis obispo california on cal poly campus property.
