Three Phase Control for Pwm-switched Autotransformer Voltage-sag Compensator Based on Phase Angle Analysis
Enhancing compensating capability is essential in a voltage-sag compensator. It involves two main aspects, first, sag detection technique and second, voltage sag compensator. Many detection techniques have been introduced to measure and to detect voltage sag, such as RMSValue Evaluation and Peak-Value Evaluation. Unfortunately, most of the techniques require a delay for sag to be detected then ...
متن کاملComparitive Study on Voltage Sag Compensation Utilizing Pwm Switched Autotransformer by Hvc
Custom Power devices like Dynamic voltage restorer and STATCOM are normally employed as a solution for mitigation of power quality problems like voltage sag and swell. In this paper new voltage sag compensators based on an autotransformer and an IGBT switched by PWM technique and Hysteresis Voltage Control (HVC) method are compared. These two schemes are able to recognize the voltage sag condit...

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...
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 کاملModeling and Simulation of Multi Layer Feed Forward Neural Network Controller Based Dynamic Voltage Restorer for Voltage Sag Mitigation
Voltage Sag/Swell are the most important Power quality issues which occur due to the utilization of increased number of sophisticated loads in Industrial and Electrical distribution system. Now-adays Industrial loads are generally based on Power electronic devices which are very sensitive to voltage disturbances. Hence it is mandatory to provide high quality power supply since; failures due to ...
