Control System of the Thyristor Voltage Regulator

Abstract

Smart Grid creation is not possible without devices that provide active and adaptive control of the electric network parameters and configuration. One such device is a Thyristor Voltage Regulator (TVR). The TVR assignment is automatic voltage and power regulation in medium voltage power distribution networks (6-20 kV). The article is devoted to the development and research of the first level TVR control system. An algorithm for two-zone sequential control of thyristors has been developed. TVR thyristors are controlled by a pulse -phase method. Diagrams for generating control pulses are presented. The software implementation of the TVR control system is performed in LabVIEW. A test program has been developed for TVR control system research. The research has shown that TVR control system is completely efficient and performs all specified functions.
