CSCI - 6838 Solar Thermal Plant Design TEAM #6 Solar Thermal Plant Overview 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. CSCI - 6838 CSCI - 6838 Solar Thermal Plant Design

CSCI - 6838 Solar Thermal Plant Design TEAM #6 Solar Thermal Plant Overview Tower with Receiver Heliostats CSCI - 6838 CSCI - 6838 Solar Thermal Plant Design

CSCI - 6838 Solar Thermal Plant Design 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. CSCI - 6838 Solar Thermal Plant Design

CSCI - 6838 Solar Thermal Plant Design TEAM #6 Problem Definition 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]. CSCI - 6838 Solar Thermal Plant Design

CSCI - 6838 Solar Thermal Plant Design TEAM #6 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. CSCI - 6838 CSCI - 6838 Solar Thermal Plant Design

CSCI - 6838 Solar Thermal Plant Design TEAM #6 Cont’d… 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.

CSCI - 6838 Solar Thermal Plant Design TEAM #6 Flowchart CSCI - 6838 Solar Thermal Plant Design

CSCI - 6838 Solar Thermal Plant Design TEAM #6 Implementation 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. CSCI - 6838 Solar Thermal Plant Design

CSCI - 6838 Solar Thermal Plant Design TEAM #6 Cont’d…. 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. CSCI - 6838 Solar Thermal Plant Design

CSCI - 6838 Solar Thermal Plant Design TEAM #6 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. CSCI - 6838 Solar Thermal Plant Design

CSCI - 6838 Solar Thermal Plant Design TEAM #6 Implementation Issues 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. CSCI - 6838 Solar Thermal Plant Design
