Performance Monitoring of Power Quality by using SFCL with Multilevel DVR

Abstract

The power distributing system based on DVR is integrated by Super conducting Fault Current Limiter gives a viable solution to attain the stabilization of voltage magnitudes where the sensitive load and voltage sag effects are minimized. Over different compensation devices, the vastly recognized multi-use dynamic voltage restorer is integrated with superconducting fault current limiter to get improved features for power quality. In this paper, novel DVR integrated with SFCL was developed effectively to improve the bus voltage as well as to suppress the fault current. It is observed that the capacity of proposed DVR along with SFCL is decreased with increased voltage at the bus when compared with single DVR method. The cost also less for this proposed method than the single DVR system. It is also observed that output power compensated and also total harmonic distortions can be reduced in this proposed method. In the proposed system by adopting the tool like MAT LAB / SIMULINK the disadvantages of single DVR method like using inverter for three level voltage source, high rating of filters, poor efficiency with respect to system performance etc., are resolved with improvised power along with reduction in total harmonic distortions.
