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.

5Solar Thermal Plant Design & Operation Tools04/19/23

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.

6Solar Thermal Plant Design & Operation Tools04/19/23

Project Abstract

Shading & Blocking

12Solar Thermal Plant Design & Operation Tools

• 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.

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.

13Solar Thermal Plant Design & Operation Tools04/19/23

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.

14Solar Thermal Plant Design & Operation Tools04/19/23

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.

15Solar Thermal Plant Design & Operation Tools04/19/23

User Interface Improvement

16Solar Thermal Plant Design & Operation Tools04/19/23

User Interface

JavaScript and CSS changes, content is central driven.

Simulated Ajax and further enhancements using Ajax.

Code Clean Up.

Make pages look alike.

Removal of unnecessary button clicks.

17Solar Thermal Plant Design & Operation Tools04/19/23

Progress
