AB  - Power quality issues have been pulling in the eye of investigates for decade. The nearness of voltage
unsettling influences at the purpose of normal coupling brings about glitch of delicate modern instruments
which ends up being matrix part disappointments. Although, there are many strategies in practice, the term
custom power relates to the utilization of energy hardware controller in an appropriate framework, particularly
to manage different power quality issues. Now the custom power devices play a vital role in the field of power
quality mitigation. The presence of sensitive loads lead to the power quality issues like sag and swell but it is
inevitable. DVR is one of the popular and efficient custom power devices most suitable distribution network
to mitigate the voltage dip and swell. Fuzzy based PI control is incorporated in this study. The main salient
feature is the use of linguistic variables rather than numerical variables. This control method depends on human
capacity to comprehend the frameworks conduct and depends on quality control rules. An experimental
investigation on the mitigation of sag and swell by using three phase Dynamic Voltage Restorer (DVR) is
proposed in this study. It is observed that the compensating capability of the DVR is somewhat lagged due the
finite voltage dip under particular loading. A fuzzy based PI scheme is therefore proposed to improve the
voltage compensation. The simulation result is appraised with experimental results and it presented it witnessed
the effectiveness of the control strategy.
