Mitigation 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 کاملImplementation of Dynamic Voltage Restorer for Mitigation of Voltage Sag
Power quality is one of major concerns in the present. It has become important, especially with the introduction of sophisticated devices, whose performance is very sensitive to the quality of power supply. The dynamic voltage restorer (DVR) is one of the modern devices used in distribution systems to improve the power quality. In this paper, emergency control in distribution systems is discuss...
متن کاملMitigation Technique For Voltage Sag & Swell By Using Dynamic Voltage Restorer
This paper presents the application of dynamic voltage restorers (DVR) on power distribution Systems for mitigation of voltage sags/swells at critical loads. DVR is one of the compensating types of custom power devices. An adequate modeling and simulation of DVR, including controls in MATLAB, show the flexibility and easiness of the MATLAB environment in studying and Understanding such compensa...
متن کاملDesign and Implementation of Dynamic Voltage Restorer for Voltage Sag Mitigation
This paper introduces the terminology and various issues related to ‘power quality’. The power quality problem is an occurrence manifested as a nonstandard voltage, current or frequency deviations that result in a failure of end use equipment’s. The main occurrence of voltage sag is always considered as one of the major power quality problems and it become severe to industrial customers. Voltag...
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...
