Abstract

In recent days the usage of non - linear loads are becoming enormous which gives an alarming signal to power system and power engineers. This paper deals with design, simulation experimentation of a shunt active power filter (SAPF) to improve power quality. Due to a large amount of non - linear power electronic equipments, and fluctuating loads (such as that of arc furnace, heavy merchant mill etc), problems of power quality have become more and more serious with each passing day. The usage of active filter mitigates the harmonics present in the current signal resulting in maintaining the quality of the power supply in the system. It is known from the fact that Harmonic Distortion is one of the main power quality problems frequently encountered by the utilities. As a result Shunt Active power filter (SAPF) gains much more attention due to excellent harmonic compensation. Here Synchronous Detection Method (SDM) is used to tune the Shunt active power filter. On owing SDM method gives away an outstanding performance under any voltage conditions ( balanced, un - balanced, balanced non sinusoidal and balanced sinusoidal). Extensive simulations were carried out; Simulation results validate the superior performance of Synchronous Detection method (SDM) . Simulation is done in Matlab/simulink software and the results shows that Total Harmonic Distortion (THD) is reduced significantly when compared with other methods.
