Tokamak plasma triangulation and elongation ratio of the constraints and magnetic fluid stability has a strong influence, so in the tokamak device polar field design, based on physical and engineering considerations pre-selected plasma How to optimize and determine the position and current of the external poloidal field coil under the geometric parameters of the balanced position is an important practical research topic.To optimize the determination of the tometric field coil of Tokamak, an effective multivariable balance optimization Method, the geometrical parameters of the predetermined plasma equilibrium configuration can be used as the objective function to optimize the position and current of the poloidal field coil, and the desired result can be obtained by applying it to the HT 7U equilibrium configuration.
