Abstract

The power quality (PQ) requirement is one of the most important issues for power system. The main problems of the power quality like voltage sags/swells in low voltage distribution systems and on the transmission side due to sensitive loads. There are different methods to compensation of voltage sag and swell, one of the most popular methods of sag and swell compensation is a series voltage regulator for a distribution transformer which addresses power quality issues in the electrical power distribution system. The proposed system is comprised of a line frequency transformer connected to a power electronic converter which is auto-connected on the secondary side. This auto-connection is facilitated by use of a high-frequency or medium frequency transformer. The proposed system has a wide range voltage compensation that can correct both the sags and swells of the grid voltage. 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 power electronic converter generates a compensating voltage, which is vector-added to the grid voltage in order to regulate the output voltage supplied to the load. The proposed system satisfies needs of smart distribution grids in terms of improved availability, equipment protection, and resilience. Detailed analysis is provided with MATLAB/SIMULINK results in order to validate the effectiveness of the proposed system.

Key Words

Distribution transformer, phase-shift modulation, ride-through system, voltage sag/swell compensation.
