The use of non-linear loads, such as
electro static precipitator (ESP) and variable speed drive (VSD), draws much
distorted currents and voltages. They lead to generation of voltage/current
harmonics and consume reactive power. Al-Tahady ESP had been designed and
manufactured at Al-Zawraa state company as an air pollution control system.
This paper presents the solution for this problem, firstly a separation of
power supplies led to proper operation of the system, this secondly encourages
to think of harmonics generated by variable speed drive. The three-phase
harmonic filter was used to compensate harmonics generated by non-linear load
(electro static precipitator and variable speed driver that derives the fan).
The instantaneous harmonic reduction theory that uses Fourier series was used
to design the harmonic filter. Power SIMulation (PSIM) and MATLAB have verified
the harmonic distortion and the active filter control scheme.
