An interline dynamic voltage restorer (IDVR) is a novel c o m p e n s a t i o n piece of equipment for sag mitigation It is made of several dynamic voltage restorers (DVRs) with a common dc link, here each DVR is connected in series with a distribution feeder. In the sag period, active power is transferred from a feeder to other one and voltage sags with long durations can be mitigated. IDVR co...

Voltage sag is one of the most severe power quality disturbances to be dealt with by industrial sector, as it can cause process disruptions and results in substantial economic loss. A short-term decreasein voltage lasting anywhere from milliseconds up a few seconds called sag. At present, wide range very flexible controllers, which capitalize on newly available electronics components, are emerg...

Power quality is one of the areas that the power sector is worried about. Power quality is the measure of practical system resemblance to ideal system. Voltage quality can be defined as the maintenance of voltage waveform shape close to ideal shape with proper magnitude and frequency. Even a slight change in voltage of the system can cause serious damage to the power system. Sensitive loads can...

Purpose. Investigation of the distribution harmonic power components in circuit a dynamic voltage restorer. Methodology. On basis differential equations restorer, search for relationship between mode parameters and elements is performed. obtained expressions, model regulator was created using methods mathematical modeling visual programming environment.. Findings. The that reflect restorer are ...

Purpose. This article proposes a new control strategy for Dynamic Voltage Restorer (DVR) in utility grid distribution system. The proposed DVR using PI tuned fuzzy logic scheme is based on replacement of conventional and voltage sag compensation system network. novelty the work consists presenting an enhanced algorithm to efficiently dynamic restorer when suddenly occurred. Methods. which provi...
