Harmonic analysis of electrical drives in DELTA Paper Mill

With the increasing of non-linear loads in electric power system, power quality distortion has become a serious issue in recent years. In paper and pulp industries, due to presence of concentrated high power non-linear loads such as electric drives, this problem is a greater concern. This paper provides an in depth discussion on harmonic distortion taking place in Delta Paper Mill (DPM). The significant amount of line side harmonic currents or voltages existing for different Variable Speed DC drives (VSD) are performed using power quality analyzer(PQA). And a design of passive harmonic filter is done for minimization of these harmonics in matlab/simulink.
