Test Results of Power System Control by Experimental SMES

H. Hayashi, Y. Hatabe, T. Nagafuchi, A. Taguchi, more

IEEE Transactions on Applied Superconductivity > 2006 > 16 > 2 > 598 - 601

The authors have developed a solenoid model coil used for superconducting magnetic energy storage (SMES) for power system control, aimed at drastically reducing the costs of the SMES system. The single solenoid model coil of 2.9 MJ is designed with the rated current of 9.6 kA, a maximum magnetic field of 5.5 T and coil charge rates equivalent to those of the practical 100 MW/54 MJ class SMES. The...

Fabrication transport properties of QMG current limiting elements

Mitsuru Morita, H. Hirano, H. Hayashi, K. Terazono, more

Physica C: Superconductivity and its applications > 2004 > 412-414 > Part 1 > 750-755

A high durability design for QMG current limiting elements was developed by reinforcement using metal bypasses. Metal bypasses with high specific resistivity were bonded to both surfaces of QMG bulk superconductor using solder. I-shaped short QMG current limiting elements with cross-sections of 2.2x0.8 mm and an effective length of 20 mm were reinforced by I-shaped NiCr or SUS bypasses. Meander-shaped...

Verification test results of the experimental model coil for power system stabilization

K. Terazono, Y. Hatabe, H. Kimura, H. Hayashi, more

Physica C: Superconductivity and its applications > 2004 > 412-414 > Part 2 > 1251-1255

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...

Properties of Fe-Zr-N Thin Films

K. Terunuma, H. Kawashima, K. Terazono

IEEE Translation Journal on Magnetics in Japan > 1992 > 7 > 11 > 886 - 890

Gases emerging from Fe-Zr-N films with various compositions during heating were analyzed by thermal desorption spectroscopy. The structures and magnetic properties of films were also investigated. H₂, N₂ and Ar were detected at 300-400??C, 500??C and 650??C, respectively. Larger amounts of N₂ were emitted by films which contained larger amounts of N₂. The changes in composition of films due to the...

Effects of Addition of Zr and Ti on Sputtered Fe-N Films

K. Terunuma, M. Miyazaki, H. Kawashima, K. Terazono

IEEE Translation Journal on Magnetics in Japan > 1991 > 6 > 1 > 23 - 28

The effects of addition of Zr and Ti on iron films containing nitrogen were investigated. Film structures and magnetic properties were studied as functions of the Zr and Ti contents. The coercive force of Fe-N films increased sharply after annealing at about 350??C, while Fe-Zr-N and Fe-Ti-N films retained a small coercive force even after annealing at higher temperatures. The addition of Zr and Ti...

Experimental study of SMES system with DC intertie for power line stabilization

H. Okada, T. Ezaki, K. Ogawa, H. Koba, more

PESC ' 00088 Record., 00019th Annual IEEE Power Electronics Specialists... > 1988 > 326 - 333 vol.1

PESC '88 Record., 19th Annual IEEE Power Electronics Specialists Conference

A superconducting magnet energy storage (SMES) system for power-transmission-line stabilization is studied using an experimental model system. It has a DC intertie section using convertors in an AC transmission line, with SMES used in series in the DC section. The distinctive characteristics of this system are that independent stabilization can be made for each AC line and that the power flow through...
