In recent years , Iranian power system harmonic levels have increased significantly due to the ever- increasing use of nonlinear loads which primarily consist of power electronic devices. A survey of power system harmonies as generated mainly by tatic convertors of aluminium factories based on simulation with EMTP Electromagnetic Transient Program) and harmonic analysis (Fast Fourier Transform) with FFT is presented. Aspects concerning harmonic injection , their undesirable effects on system components and the procedure of reduction for Aluminium factories are included.
