We present results of the comprehensive spectral and timing analysis of the transient X-ray pulsar V0332+53, which can be considered as a classical example of the Be binary system. Strong variations at different time scales of parameters of the continuum, iron and cyclotron lines were revealed in a wide dynamical luminosity range. We also searched and studied for the first time correlations between different spectral parameters as well as the ratio of the energies of cyclotron harmonics with the luminosity and pulse-phase. Based on the obtained results we proposed and debated theoretical models, including the emission of the accretion columns, reflection, distribution of the matter in the binary system, etc.
