Journal ArticleDOI
Wind farms linked by SMES systems
TL;DR: In this article, the authors introduced the concept of wind farms linked by SMES systems and applied the SMES system to a wind farm that is interconnected with a grid through a back-to-back DC link for the variable speed operation of the wind turbines.
Journal ArticleDOI

TL;DR: In this article, the authors investigated the compatibility between the plasma and low activation ferritic steel, which is a candidate material for fusion demonstration reactors, and obtained a high normalized beta plasma of βN ~ 3, having both an internal transport barrier and a steady H-mode edge.
Journal ArticleDOI
Flexible Power Interconnection With SMES
TL;DR: In this work, the SMES coils are optimized from the required mass of the structure and the leakage magnetic field to decrease the risk of the superconducting coil constructions by the effect of mass production.
Journal ArticleDOI
Effects of ELM mitigation coils on energetic particle confinement in ITER steady-state operation
Keiji Tani,Kouji Shinohara,T. Oikawa,Hiroaki Tsutsui,S. Miyamoto,Yoshinori Kusama,Tatsuo Sugie +6 more
TL;DR: In this paper, the effects of edge-localized mode (ELM) mitigation coils on the loss of NBI-produced fast ions and fusion-produced alpha particles are investigated using an orbit following Monte Carlo code.
Journal ArticleDOI
Optimization of SMES coil by using virial theorem
TL;DR: The toroidal coil with helical winding as mentioned in this paper is a hybrid coil of a toroidal field (TF) coil and a solenoidal coil helically wound on a torus, which increases the magnetic energy to 4 times the conventional TF coil with the same maximum stress.
