A comprehensive review of dynamic voltage restorers

摘要: Abstract During the last half century Power Quality (PQ) related problems have become important issues. Many solutions been proposed to address PQ problems. The most attractive and flexible way is use power electronic converter based devices such as Dynamic Voltage Restorer (DVR), Distribution Static Compensator (DSTATCOM), Unified Conditioner (UPQC), Uninterruptible Supply (UPS), other usually called custom devices. Among devices, DVR economical solution overcome voltage-related Intensive research has done in field of rather mature now. But, a survey on published papers showed that there not any paper reviews technology. This tends provide comprehensive review topologies, control strategies applications. We will consider all fast voltage compensators, i.e. Series (SSC), sag corrector, Sag Corrector (DySC), similar are also considered. All these be since they operate almost same way. Some comparative conclusions provided. can beneficial for researchers engineers, who want do investigations DVRs.
