Consideration on Damper Cylinder Design for Effectiveness of Superconducting Generator

Superconducting generators (SCGs) have many features such as high generation efficiency, small size, capability to enhance power system stability, and so on. Introduction of SCGs will offer great benefits to electric power systems. Appropriate design is necessary for SCGs to demonstrate these beneficial effects. There are some former studies on explicit expressions on relations between electrical or mechanical characteristics and structure-parameters of SCGs. Obtained expressions gave good view of generator characteristics. In this study, approximations used in the expressions are modified for recent design of damper cylinders. Some consideration on design of damper cylinders for SCGs is discussed as well
