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.

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.

Problem DefinitionTEAM #6
The radial staggered arrangement ensures that no heliostat is placed directly in front of another in adjacent rings along the reflective path to the tower[1].
In this way, a reflected beam from any heliostat passes between its adjacent neighbors on the way to the receiver, therefore more energy is obtained [1].

Requirements
User Interface enhancements
Computing the correct formulae for shading and blocking
Developing the code to implement this correct formulae by using Java 3d utilities.
Preparing a tabular form to implement the shading and blocking by varying ∆Az and ∆R between the mirrors.

Designing and implementing the functions for generalization of 8 mirrors to 24 mirrors.
Developing the test cases for testing the program
Java 3D visualization is developed such that the applet gets the real data from the web pages of the main application.

FlowchartTEAM #6
17CSCI - 6838 Solar Thermal Plant Design
ImplementationTEAM #6
The mirrors are placed in a radial stagger way.
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.
18CSCI - 6838 Solar Thermal Plant Design
Cont’d….TEAM #6
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.
19CSCI - 6838 Solar Thermal Plant Design
Test Cases
We have generated test cases by varying the locations (i.e., for different latitude and longitude values).
By varying the dimensions of the heliostat (i.e., length and width), we have calculated the shading and blocking values.
Test cases are generated for different values of ∆Az and ∆R.

Implementation IssuesTEAM #6
Unavailability of a fully functional mirror generation package encounter additional development and research to creating a working package.
The applet was developed on an standalone machine, not causing any file system structure issue.
Integration of the applet and the web application required file system changes on client machine.
Passing the real coordinates and dimensions of the mirrors caused scaling problem for the applet to display the visualization.

Visualization RequirementsTEAM #6
System Requirements:
• Solar Thermal visualization applet requires any pop-up blocking to be disabled.
• If you prefer to not disable pop-up blocking, each time you run the application, you will warned and you need to disable the pop-up temporarily.
