The work aims to detect and analyze various power quality improperness that exist in electrical power system and what the major effects seen over defined electrical power network. Here development of a novel voltage controls schemes that can compensate the detrimental effects of the power quality in three-phase power systems. In three-phase power systems the power quality is being affected by the detrimental which can be compensated through development of novel voltage control schemes. The voltage sag and swell occurred by faults in power distribution system can harm power system and user’s facility.Serious problems in the entire system obtained when voltage sags occur even for a short duration in sensitive load. Normally, voltage interruption trigger device protect entire system prevent its shutdown. Mitigation of power interruption leads to proposed research is called “DYNAMIC VOLTAGE RESTORER (DVR).”It corrects the voltage of system for sag and swell conditions by boosting the voltage during voltage sag or reducing the input voltage during voltage swell event. To provide compensation for all possible voltage level an inverter, a transformer must be required. It mainly based on the inverter system. Cost and size are the advantages of this method over existing methods which is justified through experiments and results.
