— This paper proposed the reduced rating star connected transformer based interline unified power quality conditioner. This work comprises of unified power quality conditioner connected between the two feeders, star connected transformer and LC filter. This hybrid approach significantly improves the performance of UPQC under unbalance source voltage(More)
Due to rapid increase in population and industrial growth power demand occurs. Non conventional energy resource, especially wind energy is used to generate the power at low cost. Doubly Fed Induction Generator (DFIG) is used to generate the power which has the capability to generate or absorb the reactive power to or from the grid during grid fault. The(More)
This paper presents a mitigation of power quality problems such as shortage of reactive power, voltage fluctuations, voltage and current harmonics due to wind farms connected to the non linear loads. The fault occur in the system are solved by FACTS controller such as STATCOM. The stability of fixed-speed induction generator (FSIG)-based wind turbines can(More)
This paper presents the VSI based STATCOM using Hysteresis current controller for mitigating voltage sag due to sudden increase in load. As a solution for mitigation of voltage sag generally The Static Synchronous compensator is employed. A STATCOM generates a current wave such that it compensate by cancelling out the nonlinear current waveform generated by(More)
This paper proposed a reduced rating star-connected transformer based unified power quality conditioner with distributed generator for power quality improvement. This work comprises of a three phase three wire UPQC, star connected transformer and LC filter. This hybrid approach significantly improves the performance of UPQC under unbalance source voltage(More)
