Description

Magnetically controlled saturated reactors (MCSRs) operate through changing the degree of saturation of the magnetic valve by applying different DC excitations. Due to the special structure and working mode of AC and DC excitation, the vibration of MCSRs is larger than that of the ordinary ones. In recent years, research on MCSRs vibration mainly concentrated on the causes of the MCSRs vibration. However, the core material shows different magnetization and magneto-strictive properties under different DC excitations. Therefore, in order to calculate the vibration of MCSRs accurately, it is necessary to consider the difference of magnetic properties under different DC excitations. But, so far, the vibration of MCSRs based on the measured magnetic properties of different DC excitations has not been studied. In this paper, magnetization and magneto-striction characteristics in silicon steel under different DC excitations are measured. According to the presented electromagnetic-mechanical coupled model for MCSRs, the magnetic field and vibration stress of the MCSR under different DC excitations are calculated. From the computation results, it can be see that the magnetic flux density, displacement and acceleration of the MCSR are increased with the DC excitation, and the increase degree of the different parts of the reactor is not the same, which provides the theoretical basis for vibration and noise reduction of MCSRs.
