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 کاملThe Effectiveness of Dynamic Voltage Restorer with the Distribution Networks for Voltage Sag Compensation
This paper discusses the Dynamic voltage restorer (DVR) operation and control for Voltage sags compensation. DVR is a series connected power electronic based device that can quickly mitigate the voltage sags in the system and restore the load voltage to the pre-fault value. Voltage sag associated with faults in transmission and distribution systems, energizing of transformers, and starting of l...
