Mitigation of Harmonics in Voltage and Current Using UPQC

In the current scenario, the power distribution has been performed by 3-φ, three wire or four wire structure with power limit based voltage source and source impedance which is connected to various types of loads. It is desirable that the system is required to be balanced that provide pure sinusoidal 3φ voltage with constant magnitude to the loads. Also the loads have to draw current at high power factor and balanced phases with minimum harmonics. There should not be any excessive neutral current in 4-wire system. So in that way it is easy to achieve the highest power capacity along with maximum efficiency of the supply, and minimum deviation to other devices will be ensured and safe operation will occur.
