Concepts and methods of refrigeration for superconducting power transmission cables. Final report

PDF Version Also Available for Download.

Description

An analysis of refrigeration system requirements for the superconducting power transmission cables currently under study at the three principal US cable development centers indicates the need for cable system design considering the interrelated performance of the various cable system elements to successfully develop these systems for commercial operation in the 1990's. Hardware alternatives, compatible with the application timeframe, are evaluated to establish reliable refrigerator system design to a composite requirement typical of the range of refrigerator requirements presented by the cables currently under development. In addition, a methodology is presented and utilized to establish an estimate of hardware reliability and ... continued below

Description

An analysis of refrigeration system requirements for the superconducting power transmission cables currently under study at the three principal US cable development centers indicates the need for cable system design considering the interrelated performance of the various cable system elements to successfully develop these systems for commercial operation in the 1990's. Hardware alternatives, compatible with the application timeframe, are evaluated to establish reliable refrigerator system design to a composite requirement typical of the range of refrigerator requirements presented by the cables currently under development. In addition, a methodology is presented and utilized to establish an estimate of hardware reliability and to evaluate redundancy requirements to a specific refrigerator system reliability allocation for a cable system used in previous cable development center studies. Reliability and performance of several compressor systems are evaluated. The oil-flooded screw compressor is felt to be the superior positive displacement compressor; however, the efficiency advantage resulting from preliminary design analysis of a multistage compliant toll process gas bearing centrifugal compressor system indicates a potential major operating cost reduction and the elimination of the need for oil lubrication and its subsequent cleanup requirements. Heat exchangers and expansion engines are evaluated. A preliminary design for a compliant foil process gas bearing permanent magnet turboalternator operating entirely at expansion turbine temperatures is discussed.
