Research is being carried out to integrate active filtering that is the combination of series APF and shunt APF connected back to back on the dc side and share a common dc-link capacitor with specific interface such that a common power quality (PQ) platform could be achieved. For generalized solution, a unified power quality conditioner (UPQC) could be the most comprehensive PQ protecting device for sensitive non-linear loads and Unbalanced, which require quality input supply. Also, load current harmonic isolation needs to be ensured for maintaining the quality of the supply current. The present paper describes a review for UPQC, for enhancing PQ of sensitive non-linear loads. Based on voltage compensation strategy, the control scheme has been designed, which are termed as UPQC with. A s the power circuit configuration of UPQC remains same for the model, with modification of control scheme only, the utility of UPQC can be optimized depending upon the application requirement. This paper presents a review on the UPQC to improve the electric power quality at distribution levels. Therefore, power can be transferred from one feeder to adjacent feeders to compensate for sag/swell and interruption. The performance of the UPQC as well as the adopted control algorithm is illustrated by simulation. The present work study the compensation principle and different control strategies used here are based on PI Controller of the UPQC in detail. The results obtained in MATLAB on feeder system show the effectiveness of the proposed configuration.
