METHOD OF FORMING MAGNETIC MODEL OF SHAPE AND CURRENT OF PLASMA WITH FEEDBACK IN TOKAMAK

摘要

FIELD: manufacturing technology.;SUBSTANCE: invention relates to a method of forming magnetic control systems of shape and current of plasma with feedback in tokamaks and can be used for stabilization of plasma separatrix position at reflection of action of small detachment disturbances in tokamaks. When generating feedback, variable input and output plasma parameters are used in tokamak. Input parameters are values of voltage vectors on windings of poloidal field and central solenoid of tokamak, which provide magnetic coupling with plasma. Output parameters at each moment in time represent a one-dimensional array of values of change of plasma current vectors, currents in windings of poloidal field and central solenoid, signals on magnetic loops and probes, signals proportional to vertical and horizontal displacement of magnetic axis of plasma or center of current of plasma cord. Based on said parameters, a complete plasma shape control model is obtained at each moment in time.;EFFECT: design of a plasma control model with a recovery code, shorter time for debugging a control system on tokamak, a thermonuclear reactor-tokamak or a thermonuclear power plant based on tokamak, as well as shorter experiment time.;3 cl, 16 dwg
