- 出版タイプ： NA国際熱核融合実験炉(ITER)のサテライトトカマク及びトカマク国内重点化装置として、JT-60U本体を超伝導トカマク装置に改造するJT-60SA(JT-60 Super Advanced)計画が進められている。JT-60SA化における主加熱装置である正イオンNBI加熱装置(P-NBI)は、既存の入射パルスを30秒から100秒に伸長し、12ユニットで24MWの中性粒子ビーム入射が求められる。このためには、製作から20年以上経過した現行の大型制御システム(デジタル:約4000点)を全面的に改造する必要がある。新制御システムの予備設計を、拡張性,コストパフォーマンスに加え、プログラムの自主開発の視点から行った。この結果、大型システムにおいてもPLC(Programmable Logic Controller)を主要機器に用いたユニット単位制御方式の導入により、現行制御機能を確保しつつ拡張性を有する100秒化制御システムを汎用品の組合せで構築できることが明らかとなった。The modification of the JT-60U to a fully superconducting coil tokamak, JT-60SA (Super Advanced), has been programmed as the satellite devise for the ITER (International Thermonuclear Experimental Reactor) and as the national centralized tokamak. The present positive-ion-based NBI system (P-NBI), which has been operated for 20 years and will be the main heating system on JT-60SA, is required to manage the long pulse injection extended from 30 s to 100 s at the power of 24 MW with 12 units. To realize such a requirement, the original control system handling more than 4000 digital data is to be fully remodeled. Design study of the new control system has been conducted from viewpoint of market availability, system extensibility, cost-effectiveness and independent development in programming. It has been concluded that a distributed control system using PLC (Programmable Logic Controller) could be applied to the large-scale control system for 100-s operations with satisfaction of the evaluation viewpoints.
