摘要：	This report describes a multi-year research effort that explored a wide variety of high temperature superconducting (HTS) technologies for use on the San Francisco Bay Area Rapid Transit (BART) system. The genesis of this research derived from the examination of low voltage conditions caused in part by the long distance between power supplies serving the Transbay Tube, a critical transportation link connecting San Francisco and Oakland. When four or more trains accelerate simultaneously in the Tube, voltages at the trains can drop below the reset point, causing the protection circuitry to disconnect effected trains from the rail. Any resulting delay can negatively impact operating schedules and operating costs. The project researched several potential technical solutions: superconducting energy storage (SMES), cryogenic power supplies, HTS transformers, and HTS cables. This report first chronicles the evolution from SMES to HTS and establishes HTS as the leading candidate technology. Next, it summarizes the analyses and findings from simulation models developed to study HTS scenarios. Finally, the report details an economic analysis of HTS technology and provides recommendations and conclusions in regard to the current and future status of HTS in a transportation and/or utility application.
