Research of Thyristor Voltage Regulator Effect on Power Flows Control in Distribution Electric Networks

Abstract

The article is devoted to the power flows redistribution process research in distribution electric networks (DEN) with thyristor voltage regulator (TVR). TVR is intended to regulate power flows and voltage stabilization in the medium-voltage network of 6-20 kV. The problems in the medium-voltage network of 6-20 kV were analyzed and solutions were determined. It was established that the key development trend of DEN is the engineering and adoption of devices based on D-FACTS technologies. In addition, we considered the features, technical characteristics and control system of TVR. The research of power flow distribution in electric system was based on a simulation model of DEN with TVR. TVR allows to regulate power flows by changing the amplitude and phase angle of the voltage, with the help of longitudinal-transverse regulation. The results have shown that the TVR allows to align load schedules, to stabilize the voltage level in complex networks with unevenly loaded nodes and to realize optimal distribution of power flows in the electrical network.
