Power quality in distribution system is one of the chief concerns in the modern industrial and commercial applications. Power quality problem is an occurrence manifested as a non-standard voltage, current or frequency that results in a failure of end user equipments. However critical problems in power quality have been recognized such as transients, sags, swells and harmonic distortions. Out of these...
Power quality is a big problem due to the increase in modern sensitive loads which are connected to the distribution network. One of the major problem dealt in this paper i.e. the voltage sag. This problem is very severe for the industrial areas as it can effect on malfunctioning of several sensitive electronic equipment's and devices. Dynamic Voltage Restorer (DVR) can be solution for this problem,...
This paper presents a comparative study through simulations of two different controllers for generation of PWM pulses for an Active Power filter namely Hysteresis Current Control and State Vector Pulse Width Modulation. A synchronous reference frame based controller for three phase three wire voltage source active power filter has been selected for the study. Constant capacitor voltage technique is...
