Abstract

As a quench protection method in an SMES, a dumping resistor method and an enthalpy method are considered. The former is a conventional method, but the latter has not been experimentally examined yet, although it has been shown to be suitable for future SMES. In addition, a new control method, QI simultaneous control, has been also developed as a practical application of the SMES. The performance or the enthalpy protection technique is verified by a helium dumping method, and the QI simultaneous control is also successfully examined using a power network simulator
