A New Control for Series Compensation of UPQC to Improve Voltage Sag/Swell

Voltage sag/swell is one of the most frequently power quality problems which affects the power systems with sensitive loads. The unified power quality conditioner (UPQC) is capable of mitigating the effect of voltage sag/swell at the load or point of common coupling (PCC). In this paper, a new control of UPQC is proposed based on combining the sag detection and voltage injection established on ...

The Impact of Superconducting Fault Current Limiter Locations on Voltage Sag in Power Distribution System

In this paper, the impacts of installing superconducting fault current limiter (SFCL)in radial and loop power distribution system are evaluated to improve voltage sag in both cases of with and without distributed generations (DG). Among various SFCLs, the hybrid type with a superconducting element in parallel with a current limiting reactor (CLR) is selected. This is more effective than resisto...

PV System with Virtual DC Bus for Cost Effective Grid Supply for Commercial Purpose

The main objective of this project to control the common mode leakage current by using virtual dc bus with PV systems. The power which we receive form the PV panel is not a constant supply due to various condition. In order to overcome this issue we are using Buck Boost converter for generating constant voltage supply to the inverter. The negative pole of the dc bus is connected directly to the...
