The authors are engaged in technological endeavors to create a coil at a drastically reduced cost with the aim of making it practical for SMES for power system stabilization. With focus on its novel conductor material and uniquely shaped coil, which were exclusively developed with the target of reducing the cost of the coil, an experimental model coil was devised. It is characterized by a single solenoid coil made of aluminum stabilized NbTi CIC. Experiments such as a rated 9.6 kA current-carrying test and current interrupting test were conducted to examine the performance of the model coil. The test results proved that the SMES model coil would perform as initially designed. [Copyright &y& Elsevier]

Since 1999, a Japanese national project to realize commercially feasible SMES for designated applications has been promoted. Model coils for power system stabilization, load fluctuation compensation and frequency control have been fabricated and tested. In this paper, we introduce the present status of the project, including feasibility studies of an HTS SMES. [ABSTRACT FROM AUTHOR]
