Mitigation of Voltage Fluctuation in Distribution System using Sen Transformer with Variable Loading Conditions

The voltage fluctuation is the most critical as well as common power quality problem which results in the flickering of domestic lighting and it negatively influences appliances in industries in the distribution network. This problem can be overcome with different voltage regulating devices like DVR, D-STATCOM, UPQC, etc but they are having their own limitations. This paper proposes the Sen Transformer (ST) to mitigate voltage fluctuations in the distribution network by achieving a flat voltage profile with variable loading conditions. The ST is a realized practical solution and is devoted to controlling power flow in the system. The ST always generates a pure sinusoidal compensating voltage of system frequency. The ST is implemented as a voltage regulator in the distribution line in the presented work to get flat voltage at end consumers.
