PROJECT TITLE :

Series Voltage Regulator for a Distribution Transformer to Compensate Voltage Sag/Swell - 2017

ABSTRACT:

This paper presents a series voltage regulator for a distribution transformer that addresses power quality problems in the electrical power distribution system. The proposed system is comprised of a line frequency transformer connected to a Power Electronic converter that is autoconnected on the secondary aspect. This autoconnection is facilitated by use of a high-frequency or medium-frequency transformer. A simplified strategy to compensate for voltage sags and swells on the grid side, by providing continuous ac voltage regulation, is discussed. When a voltage sags or swells occur, the ability electronic converter generates a compensating voltage, which is vector-added to the grid voltage in order to control the output voltage equipped to the load. The proposed system satisfies desires of smart distribution grids in terms of improved availability, equipment protection, and resilience. Detailed analysis is provided with experimental leads to order to validate the effectiveness of the proposed system.
