Abstract

A computational technique is proposed for the analysis and design optimization of inductive-type superconducting fault current limiters (SFCL) with variable impedance for power systems application. The technique is applicable for a wide range of magnet systems. The paper is focused on the analysis of electromagnetic transients. A methodological example of a model SFCL is presented. Numerical experiments are described to study nonlinear effects at saturated and unsaturated states. Results demonstrate that the nonlinear magnetic behavior of the SFCL components affects noticeably the accuracy of predictions. [ABSTRACT FROM PUBLISHER]

Abstract

Currently reconstruction is initiated on the T-15 tokamak at the Institute of Tokamak Physics, NRC “Kurchatov Institute”. The purpose of the reconstruction is to build the facility with a small aspect ratio A=2.2, elongated cross-section (k=1.8) and the divertor with a major radius of 1.67 m, long plasma current pulse of 2 MA up to 10 s and powerful auxiliary plasma heating (up to 15 MW). The facility is intended for demonstration of the plasma steady-state burning with high parameters for physics research to support the ITER program and program for development of volumetric neutron sources. The reconstruction involves replacement of the existing superconducting TF magnet system and cryoresistive PF system by the “warm” system. The developed magnet system provides the above-mentioned tokamak parameters. The magnet system of the new facility use of the T-10 and T-15 infrastructure, thus essentially determinig the choice of its main parameters [ABSTRACT FROM PUBLISHER]

Abstract

A feasibility has been demonstrated for numerical reconstruction of geometrical displacement or deformations of the winding occurred in the manufacture and assembly of magnet coils using magnetic measurements, that is one of the principal issues for the quality control of the magnet. For validations of the proposed approach, test results of reconstruction of possible misalignments and deviations of the ITER coil are presented. [ABSTRACT FROM AUTHOR]
