CEC-09 - Cryogenics for Power Applications, Energy, Fuels and Transportation
Poster Presentation
Approaching to commercializing of High Temperature Superconducting (HTS) power applications is becoming more active. And cooling system is very important and essential for practical HTS power applications. HTS power applications on commercial scale will require cooling system which has cooling capacity from 2kW to 10kW at 65K, high reliability (long maintenance interval) and compactness. Taiyo...

CEC-09 - Cryogenics for Power Applications, Energy, Fuels and Transportation
Poster Presentation
Cryogenic system complexity presents a major challenge to the implementation of superconducting technologies. At MIT, we have developed concepts to simplify the cryogenic environment for superconducting rotating machinery, such as HTS motors and generators. We present cooling schemes for the rotor of a high-speed rotating machine that avoid the use of rotating cryogenic seals, which are...

CEC-08 - Cryogenic Power Cables and Leads
Poster Presentation
In this study, a superconducting fault current limiter (SFCL) with two magnetic paths using E-I iron core was proposed and its peak current limiting characteristics were analyzed. For the suggested SFCL to effectively perform the peak current limiting operation, the design of the SFCL considering its electrical equivalent circuit for E-I iron core was needed. In addition, the analysis on the...

Poster Presentation
From the point of view of environment and energy problems, the renewable energies have been attracting attention. However, fluctuating power generation by the renewable energies affects the stability of the power network. Thus, we propose a new electric power storage and stabilization system, Advanced Superconducting Power Conditioning System (ASPCS), which consists of a Superconducting...
