Authors: Berry, Gregg; <Argonne National Laboratory, Argonne, Illinois) Keywords: structure and design, space energy conversion, sps general Abstract: Interest in examining alternative power system concepts have increased recently. Such analysis has become very involved, regardless of the degree of sophistication employed in modeling the individual component models of the system or the extent of the property data base used. Specification of the ATTACHMENT : models, interconnecting flow streams, property data, constraints, independent variables and objective function (for optimization problems) can quickly become a formidable task, especially in attempting to conform to the format of any particular systems code. The systems code presented herein has been designed for the non-expert user by the development of a sophisticated language translator and executive code preprocessor. These two modules also permit great flexibility in allowing the user to specify the system in his own style rather than conforming to a rigid structure determined by a precompiled computer code. The user may also choose his only naming convention and can use free format input. This paper will also be concerned with the solution procedures available. The systems code uses Powell's hybrid method for solving N-dimensional nonlinear equations and Brent's method for a 1-dimensional equation. Powell's variable metric constrained method is used for N-dimensional non-linear optimization and Brent's method for the optimization of one variable. This systems code (SALT) has been written to be used as an evolving analysis tool rather than a definitive encompassing code. It is easy to modify the code (which is completely modularized) to meet particular needs, especially to include the users component models which may be of interest to him.

(Paper No. 1-3) Authors: Cohen, M. E.; Keywords: solar cells, nuclear, onboard power storage and distribution, SPS general, Abstract: Military spacecraft missions in the communication, navigation and meteorological areas currently require power in the general neighborhood of 1-2 KW. This is expected to grow moderately to 5-15 KW by the 1990's due co onboard data processing, enhanced communication cross-linking, increased on- ATTACHMENT : station housekeeping requirements and higher powered downlink transmitters to support the increased use of small and diversified ground c ommu n ication facilities.
