Voltage Sag Compensation using SMES Based DVR Technology & Pi Controller

Abstract

Power quality is one of the most important topic that electrical engineering have been noticed in recent years. This paper describes the super conducting magnetic energy storage SMES based dynamic voltage restorer protect consumers from the grid voltage transients. A fine solution to power quality and optimization related concerned issues can be easily provided through DVR..Voltage sag is the most prominent problem as paer the P-Q issue. The voltage sag is mitigated and real power is restored and thus wastage is overcome, providing protection to consumers from grid voltage fluctuations by the Superconducting magnetic energy storage (SMES) technology based DVR. Power flow stabilization and control in the transmission network level are some of the increasing interest in application of Superconducting magnetic energy storage (SMES) systems. The properties and characterstics of high energy density and quick response incorporates a superconducting magnet as the energy storage unit to improve the compensation capability of DVR. This paper analyses the operation principle of the SMES based DVR, and designs the DVR output voltage control method using MATLAB SIMULINK, the models of the SMES based DVR is established, and the simulation tests are performed to evaluate the system performance.
