A novel approach to linearization of the electromagnetic parameters of tokamaks with an iron core

P. Fu, Z.Z. Liu, J.H. Zou2002年Fusion Engineering and DesignIF 1.7出版社

AbstractThe equivalent model of an iron core tokamak is developed, in which the electromagnetic parameters of several pairs of coils in opposite series (PCOS) are not dependent on the saturation of the iron core during tokamak operation. With this the electromagnetic parameters of all the coils in an iron core tokamak can be linearized, As an example, the electromagnetic parameters of Hefei Super-conductive Tokamak with iron core (HT-7) are linearized, and it is in good agreement with the experimental results. The linearization approach can be applied in real time plasma control and electromagnetic analysis.

鉄芯トカマクの等価モデルを開発し、逆直列(PCOS)接続された複数のコイル対の電磁パラメータが、トカマク運転中の鉄芯飽和に依存しないことを示した。これにより、鉄芯トカマクにおける全コイルの電磁パラメータを線形化することができる。例として、鉄芯を有するHT-7超伝導トカマクの電磁パラメータを線形化し、実験結果と良好な一致を示した。この線形化手法は、リアルタイムのプラズマ制御および電磁解析に適用可能である。
