Currently, all of the main elements of the T-15 design have acquired their specifics, and, therefore, it is possible to conduct a sufficiently detailed analysis of future experiments. In this paper, we simulated the stage of current increase and the beginning of transition to a configuration with a divertor. We were interested in the degree of correlation between the scenario calculations, which were carried out using various numerical codes, the existence or absence of the problem with vertical plasma instability at this stage, and the accuracy of restoration of the plasma boundary, which depends on the error of magnetic sensors. As a result of calculations, it was possible to show that the stage of discharge, which was considered by us, is quite real from the point of view of its realization.
