3. 1. Introduction Solar power plants: It has a centralized receiver which produces electrical power by converting the sun’s energy in to high temperature heat using various mirror (heliostats) configurations Central receiver technology for generating electricity has been demonstrated in the solar one pilot power plant at Barstow, California

4. 2. Central Receiver Technology  System Description 1.Heliostats 2.Receiver/Tower 3.Field Layout

5. 2.1 Heliostats  The heliostat is composed of several mirror modules rather than having single large mirror

6. 2.2 Receiver - Tower  The receiver, placed at the top of a tower, is located at a point where reflected energy from the heliostats can be intercepted more efficiently  There are two basic types of receivers 1. External 2. Cavity

7. Receivers External receiver Cavity receiver

8. 2.3 Field Layout  Best position for locating heliostat relative to the receiver  How high to place the receiver above the field  Field layout depends on the following loss mechanisms 1. Cosine effect 2. Shadowing and blocking

9. Shadowing and Blocking  Shadowing occurs at low sun angles when heliostat casts its shadow on a heliostat located behind it  Blocking can be observed in a heliostat field by noting reflected light on the backs of heliostats
