5. Introduction • A field of thousands of movable mirrors called heliostats and a tower. • A receiver at the top of the tower. • Generating electricity from the energy of the sun. Solar Thermal Plant Design & Operation Tools

6. Previous Capstone Work • Computed solar position. • Mirror specification from user/files/database. • Formation of the field in a grid view. • Solar vector and receiver vector to calculate the normal. • Azimuth and Altitude of the Heliostat. Solar Thermal Plant Design & Operation Tools

7. Project Abstract • User Interface Enhancements. • Dynamically populating the plant location. • Placing eight mirrors in each cell of the grid. • Compute shading and blocking by changing the distance between neighboring mirrors in a cell. Solar Thermal Plant Design & Operation Tools

8. Requirements • Improving User Interface. • Compute shading and blocking. • Sun vector. • Normal. • Mirror Size (W, H). • Distance between mirrors/heliostats. • Research on geometry. Solar Thermal Plant Design & Operation Tools

12. Shading & Blocking • A field of heliostats suffers losses caused by shading and blocking by neighboring heliostats. • The shading and blocking should be calculated for different ∆R and ∆Az. • ∆R is the radial spacing. • ∆Az is the Azimuthal spacing. Solar Thermal Plant Design & Operation Tools

13. Problem Specifications • Find the equation of the plane of target mirror. • Find the co-ordinates of the target mirror on the absolute coordinate system. • Find the co-ordinates of the source mirror on the absolute coordinate system. • Compute the sun vector(X,Y,Z) in the absolute coordinate system. • Compute the projections of the source mirror corners with respect to sun vector on to the target mirror plane. • Compute the intersection area of the target mirror and the projected plane. Solar Thermal Plant Design & Operation Tools

14. Implementation • Once the shading and blocking between two mirrors is achieved it can be implemented on to eight mirrors. • The distance between the mirrors can be varied. • The Shading and Blocking for different values of ∆R and ∆Az are to be noted and stored.

15. User Interface • Populating the longitude and latitude for the selected location. • Dynamically storing the longitude and latitude of new location. • Making it more professional web application instead of website. • Integrating several pages into a single page. • Proper demarcation of steps.
