Abstract
The paper is about improving a secure supply of phase-sensitive appliances in the AC network. Mainly, it deals with short-time sags of energy delivering or/and influence of non-linear loads on the power supply network [1]–[4] without a change of a phase position of the supply voltage. Application of combine techniques of dynamical voltage restorer (DVR) and uninterruptible power supply (UPS) makes possible the voltage sags compensation. This needs a fast control method which can provide a voltage recovery for phase-sensitive loads during a few/several calculation steps, so, the dead-beat regulator is used. The simulation results in Matlab/Simulink without and with compensation control are given in the paper.
