Abstract
Power System is expanding to fulfill the power need of customers. The customers are using linear and nonlinear loads without seeing their effect on the quality of power. The internal structure, mathematical modeling and controlling of unified harmonic compensator are discussed in detail and its performance is analyzed in the distribution power system feeding linear and nonlinear loads. The results obtained are showing the effectiveness of unified harmonic compensator in improving the quality of power obtained at customers end. The waveforms of electrical parameters at the point of common coupling(PCC) are compared with and without compensator in the system. The control unit of shunt active filter is effectively generating the reference signal for power electronic devices used. This analysis will be helpful in designing and locating the compensator in the system to get the improved quality of power and can be expended to reduce the cost and size of this compensator.
