Harmonic Analysis of the Thyristor Regulator Output Voltage

Abstract

The problem of improving the quality of electricity in medium voltage (MV) distribution electric networks (DEN) can be solved with the help of intelligent semiconductor booster devices. A variant of such a device is the thyristor regulator of booster voltage (TRBV), developed by the NNSTU. The operation of semiconductor devices causes a non-sinusoidal voltage of the network. The article is devoted to the investigation of the TRBV output voltage harmonic composition. The developed Simulinkmodel of a MV DEN segment with TRBV allows conducting the research. The modes of the longitudinal, transverse and longitudinal-transverse voltage regulation are considered. The output voltage of the TRBV meets the requirements of the regulatory standards.
