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 ...
متن کاملMitigation of voltage sag/swell using Dynamic voltage restorer (DVR)
The most noticeable topic for electrical engineering is power quality in recent year. Power quality problem is an occurrence manifested as a nonstandard voltage, current or frequency. Utility distribution networks, sensitive industrial load and critical commercial operation suffer from various types of outages and service interruption can cost significant financial losses. One of the major prob...
متن کاملAn Enhancement Method for the Compensation of Voltage Sag / Swell and Harmonics by Dynamic Voltage Restorer
Now a days, the problem of voltage sags and Swells create a severe impact on sensitive loads in industries . Due to which load shedding and over voltages might occur. Several custom power devices can be used to overcome this problem. Of these power devices Dynamic Voltage Restorer (DVR) is one of the most reliable and efficient custom power devices used in power distribution network. This paper...
متن کاملUnified Power Quality Conditioner (UPQC) During Voltage Sag and Swell
This paper deals with conceptual study of unified power quality conditioner (UPQC) during voltage sag and swell on the power distribution network and researches profoundly on the coordinated control of UPQC (Unified Power Quality Conditioner). By analyzing the radical reasons of coupling effect between UPQC series unit and shunt unit, a simple and practical coordinated control strategy for UPQC...
متن کاملDesign, Modeling and Simulation of Dynamic Voltage Restorer for Voltage Swell/Sag Mitigation
While early FACTS devices consisted mainly of thyristor-controlled/switched RLC/transformer components, the newer generation is based on the self-commutated voltage-source power converter. Different shunt FACTS devices, namely Static VAR compensator (SVC) and Static Synchronous Compensator (STATCOM), Dynamic voltage restorer (DVR) in transmission line using the actual line model. This paper des...
