4. TEAM #6 Introduction • Solar Thermal power plants are used to generate electricity from the energy of the sun. • Heliostats (mirrors) and a receiver located at the top of a tower are used. Solar Thermal Plant Design & Operation Suite of Tools

6. TEAM #6 Introduction • Shading occurs when a heliostat casts its shadow on another heliostat located behind it. • Blocking occurs when a heliostat in front of another heliostat, blocks the reflected suns energy on its way to the receiver. Solar Thermal Plant Design & Operation Suite of Tools

7. TEAM #6 Terms • Heliostat - Movable mirrors that are used in the solar energy power plants. • Grid - Pattern of mirrors represented in rows and columns. • Cell - The number of mirrors arranged per square area in a structured way Solar Thermal Plant Design & Operation Suite of Tools

8. TEAM #6 Previous Capstone Work • Implemented formulas to calculate the shading and blocking between the representative mirrors and the other mirrors. • Developed a web application which calculates the levels of shading and blocking for a given grid arrangement at specified longitudes and latitudes. • Stored the results obtained in a text file . Solar Thermal Plant Design & Operation Suite of Tools

9. TEAM #6 Problem Specification • Verify the computation of shading and blocking for 8 mirrors done by the previous capstone team. • Calculate shading and blocking for 24 mirrors. • Use Java-3D software to show the graphical representation of levels of shading and blocking. • Use slit mirror design to maximize the efficiency of heliostat setup.

10. TEAM #6 Problem Specification • Improve the previous capstone project by storing the results in a database and provide an application to retrieve those results. • Compute annual energy based on yearly insolation data . • Create a set of test cases.

11. TEAM #6 Problem Specification • Calculate (x,y) coordinates of the neighboring mirrors to the central mirror in the cell. • Initially the minimal ∆R and ∆Az are calculated where ∆R = the radius of the circular rings in the field ∆Az = distance between the centers of two mirrors. • ∆Az and ∆R are varied until we get minimal shading and blocking.

13. TEAM #6 System Architecture Solar Thermal Plant Design & Operation Suite of Tools

14. TEAM #6 Implementation • The mirrors are placed in a radial stagger way and the mirrors in each cell are kept in the form of rhombus. • The central mirror in a cell is considered as a reference mirror for calculating shading and blocking. • The distances between the mirrors are calculated with respect to the diagonal length of the central mirror. Solar Thermal Plant Design & Operation Suite of Tools

15. TEAM #6 Implementation • Consider the source mirror • Put the eight mirrors • around the source mirror • Calculate shading and blockings • Add sixteen more mirrors and calculate the shading • and blocking of each one. 16 14 13 11 12 8 9 10 6 5 ΔR 2 1 2 1 Source Mirror ΔAz 4 3 4 3 7 6 5 7 8 15 Solar Thermal Plant Design & Operation Suite of Tools

21. TEAM #6 User Interface • Allows the user to populate the longitude and latitude values for a particular location. • Enables the user to store the longitude and latitude of a new location. • A full scale web application instead of a webpage. • A more compact representation of the levels of shading and blocking through the Java3D visualization interface.
