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 کاملEffectiveness of Dstatcom in Mitigation of Sag and Swell
Quality of power has always been an area of interest and needs continuous improvement for transmission and distribution system. In this paper the power quality issues viz. sag and swell are being analysed for a distribution network. The effectiveness of DSTATCOM has been explored so that these above said power quality issues are mitigated up to a considerable extent. The behaviour of the device...
متن کاملA 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 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 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...
