چکیده
As a consequence of sensitive, diverse and complex loads in today's distribution networks, improving power quality in distribution systems has attracted great attention. Power quality problems include voltage sags, transient interrupts and other distortions in sinusoidal waveforms. There are various methods for power quality modification. Using power electronic devices in the form of custom power devices is one of the methods by which power quality problems might be addressed. Dynamic Voltage Restorer (DVR) is one of these devices which is connected in series to distribution networks. It is able to control voltage amplitude and phase through injection of voltage to the network. It is employed to compensate for voltage sags via injecting series and synchronous three phase voltage. Consisting of three single phase inverters and a DC bus, it is able to protect sensitive loads against different types of voltage sags and other disturbances in the power supply. Moreover, it is capable of generating and absorbing active and reactive power. In this paper a DVR is modeled and simulated to investigate its application in improvement of distribution networks power qualityکلیدواژه ها
