Abstract: A vortex system of the Bi-2212 superconductor in an external magnetic field linearly increasing at different rates has been numerically simulated using the Monte Carlo method. The effect of the concentration and distribution of pinning centers on the penetration of the magnetic flux has been studied. Features of the flux penetration have been observed and described in terms of the vortex system dynamics and the conditions for their occurrence have been determined. The increasing dependences of the saturation field on the defect concentration in homogeneous and inhomogeneous samples have been obtained.

Keywords: HTS, pinning, Abrikosov vortices, pulsed magnetization, Monte Carlo method.
