Abstract

The invention discloses a plasma current calculation method and device, and the method comprises the steps of obtaining the external diagnosis data of a plasma current, inputting the external diagnosis data into a preset target current calculation model, and obtaining a target current value outputted by the target current calculation model, wherein the target current calculation model is obtained according to a target prior probability model, the target prior probability model is constructed according to the reference gun current, and the target current value is determined as the plasma current. According to the method, the target prior probability model constructed by reference shot current is introduced, the inversion result of a target historical discharge operation experiment similar to discharge target data is considered, the model structure of the prior probability model is optimized by using the empirical data of the target historical discharge operation experiment, so that the model structure of a posterior probability model can be optimized, the calculation precision of the posterior probability model on the plasma current is improved, the errors of plasma current inversion by using the external diagnosis data are reduced, and the inversion precision is improved.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a plasma current calculation method and device. Background technique [0002] With the development of science and technology, controlled nuclear fusion technology has been continuously improved. [0003] A tokmak is a ring-shaped container that can achieve controlled nuclear fusion through magnetic confinement and vacuum insulation. During the discharge experiment of the tokmak device, the discharge process can be studied and optimized by obtaining its discharge parameters. [0004] Among them, the plasma current is an important discharge parameter. The plasma is located in the inner vacuum chamber of the tokamak device. Generally, the plasma current cannot be obtained by direct measurement, but the plasma current can be inverted by the data measured by the measuring instruments deployed outside the inner vacuum chamber. to determine the plasma current. [0005] At pr...
