Wisconsin superconductive energy storage project

Abstract

In 1970, research effort was initiated at the University of Wisconsin by two Engineering College faculty members to determine the merits of superconductive inductor energy storage units, called I-C (inductor-converter) units, for electric power systems. Interest in the project increased rapidly. The first research proposal was prepared in 1971. The first paper was presented in Kyoto, Japan, at INTERMAG in April 1972. In July 1974, a comprehensive book-length report entitled, ''Wisconsin Superconductive Energy Storage Project'' Vol. 1, was completed which summarized the results of the conceptual design and feasibility studies. It is generally believed in view of this report and related research efforts, particularly at Los Alamos Scientific Laboratories, that superconductive-inductor energy storage for bulk power transmission systems is technically feasible. It is the purpose of this paper to report on recent progress in the design of I-C units and to show how projected costs may be affected.
