Description :

Recently wide spread of power electronic equipment has caused an

increase of the harmonic disturbances in the power systems. The nonlinear

loads draw harmonic and reactive power components of current from ac mains.

Current harmonics generated by nonlinear loads such as adjustable speed

drives, static power supplies and UPS. Thus a perfect compensator is

required to avoid the consequences due to harmonics. To overcome problems

due to harmonics, Shunt Active Power Filter (SAPF) has been considered

extensively. SAPF has better harmonic compensation than the other

approaches used for solving the harmonic related problems. The performance

of the SAPF depends upon different control strategies. This paper presents

the performance analysis of SAPF under most important control strategy

namely instantaneous real active and reactive power method (p-q) for

extracting reference currents of shunt active filters under unbalanced load

condition. Detailed simulations have been carried out considering this

control strategy and adequate results were presented. harmonic control

strategy is applied to compensate the current harmonics in the system. A

detailed study about the harmonic control method has been used using shunt

active filter technique.
