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 کاملSimulation and Implementation of DVR for Voltage Sag Compensation
Power quality is one of major concerns in the present era. It has become important, especially, with the introduction of sophisticated devices, whose performance is very sensitive to the quality of power supply. Power quality problem is an occurrence manifested as a nonstandard voltage, current or frequency that results in a failure or mis-operation of end user equipments. One of the major prob...
متن کاملEffective Controller Design for the Dynamic Voltage Restorer (DVR) for Voltage Sag Mitigation in Distribution Utilities
The voltage sag detection algorithm and control algorithm synthesis of the dynamic voltage restorer (DVR) are proposed. The double synchronous reference frame phase-locked loop (DSRF-PLL) is applied for the voltage sag detection, which is able to calculate the phase angle of the positive-sequence fundamental component of grid voltages even under unbalanced and distorted grid voltages. The effec...
متن کاملHybrid Approach for Voltage Sag Mitigation in Distribution System
Voltage sag is one of the severe forms of power quality problems in distribution network. It should be mitigated as soon as possible for preventing the load from getting damaged. In the paper, a hybrid approach for voltage sag mitigation in distribution system is proposed. Mitigation is performed by optimally installing DG units in the network. In the hybrid approach, we use two well known Arti...
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...
