Abstract:
Since the superconductivity was discovered a century ago, various new superconductors have been found endlessly. However, a number of superconductors have lost their practical applications duo to limitations from the intrinsic properties, low temperature requirement, synthesis conditions, and environmental factors. A variety of applications for superconducting materials are summarized particularly with respect to the field of advanced power grids in the near future. The development and evolvement of practical superconducting materials are analyzed, together with the market demands. National projects regarding superconducting applications for a few major advanced countries are introduced as well, and the necessaries, significance and contributions to the society for development of the secondary generation superconducting tapes and relevant novel superconducting devices, such as grid cables, fault current limiter, power transformer, and motor etc. in the metropolis like Shanghai, are roughly indicated
