Design study for a 25 kwe dish/stirling system


Joule II Contract JOU2-CT93-0299 Design Study for a 25 kWel Dish/Stirling System Schlaich Bergermann und Partner in Germany have built, after successful prototyping, three 9 kWel Dish/Stirling solar thermal power plants at the European Solar Test Centre (PSA) in Spain. The three systems started operation in spring 1992 and had accumulated more than 10,000 operating hours by October 1993. Continuous operation is going on in cooperation with the German Aerospace Research Establishment (DLR) and the Centro de Investigaciones Energeticas, Medioambientales y Tecnologicas, Plataforma Solar de Almeria (CIEMAT.PSA).

Studies of the economical and technical potential of solar thermal power plants in the Mediteranean area have indicated, besides the small 5 - 10 kWel units, a considerable potential for larger ca. 25 kWel units.
The goal of this joint Project is to design a 25 kWel Dish/Stirling unit based on operational experience on site and the results of the studies.
At the end of the project a final report will be delivered which includes
* a description of the 25 kWel Dish/Stirling System and its components, * a set of technical drawings and specifications for each component, * the expected yearly energy output at two site locations, i.e. in different meteorological conditions,
* first system cost estimates for 1, 10, 100, 1000 units.

Joule II Contract JOU2-CT-93-0299 Design Study for a 25 kWel Dish/Stirling-System Project Description Schlaich Bergermann und Partner (SBP) have jointly with the Centro de Investigaciones Energeticas Medioambientales y Tecnologicas, Plataforma Solar de Almeria (CIEMAT.PSA) defined the following work packages to design a 25 kWel
Dish/StirlingSystem: - Routine test and operation of the already existing three 9 kWel Dish/Stirling-Systems of SBP will be continued on the PSA and the recorded data will be evaluated to form the basis of the further development of the 25 kWel Dish/Stirling-System.

- Components : Concentrator, concentrator support structure, Stirling support structure, foundation, drives and system control will be designed on the base of the 9 kWel Dish/Stirling-System of SBP and a 25 kWel Stirling unit will be adapted for this solar application.

- System performance simulation with the predicted System efficiency and measured meteo data sets of Barstow (USA) and Almeria (Spain) .
