Research of Dynamic Operation Modes of Transformer Voltage Regulator on Mathematical Model

Abstract

Transformer voltage regulator can be used to regulate the voltage in the electrical network. The authors developed a voltage regulator prototype. Transformer regulator introduces a boost or buck voltage in the line and allows one to adjust the network voltage in amplitude (longitudinal voltage control) and phase (transversal voltage control). Mathematical models of the network with transformer voltage regulator developed in SamSim. The simulation results allowed determining the parameters of the longitudinal and transverse perturbations that can be compensated by voltage regulator. The influence of the transformer regulator model parameters on its dynamic characteristics has been investigated.
