In these days the power quality related problem
become more severe due to the power electronics devices.
Passive filters are not able tocompensate the power quality
problems. UPQC (Unified power quality conditioner) is a
device which can compensate the current and voltage related
problem simultaneously. In this paper two control technique
is explained to compensate the voltage sag, swell, harmonics,
interruption and harmonic compensation.

This paper proposes the control scheme for the UPQC
operation using the UVT extraction for the series filter and
instantaneous P-Q theory for the shunt filter reference
signal generation. The results and simulation developed
here in the MATLAB/SIMULINK environment. It can
also shown here that all the power quality related problem
can be taken care by that scheme. It can also observe here
that the harmonics present in load side and the supply side
below the IEEE 519 standard[8].
