Abstract
Plate-type electrostatic precipitators are the main installations of separating particles from industries (especially for large gas flow) and must operate in its electromagnetic environment without interfering with the operation of other equipments. The power supplies have non-linear elements that cause distortions of the sources currents. The main objective of this work is to analyze measure and simulate currents, voltages and powers from the sources that are used (thyristor-controlled reactor type) taking into account a new electric model, more close to reality, of the ESP sections. It’s analyzed the modification of the current waves shape and THD in case of using passive filters.DOI: http://dx.doi.org/10.5755/j01.eee.19.5.2344

Summary
In the last decades the use of power electronics equipments has quickly increased. The power electronics technology and its progress depend on the advantages of semiconductor technology [1], [2].The plate-type electrostatic precipitators (ESPs) have been used to collection the dust, fume, and mist particles from following processes: electrical power plants, cement industry, iron steel works, glass industry, and other industries.The ESPs are made from a number (usually, three or four in the most applications) of series sections. In the last decades the use of power electronics equipments has quickly increased. The power electronics technology and its progress depend on the advantages of semiconductor technology [1], [2]. The plate-type electrostatic precipitators (ESPs) have been used to collection the dust, fume, and mist particles from following processes: electrical power plants, cement industry, iron steel works, glass industry, and other industries. The ESPs are made from a number (usually, three or four in the most applications) of series sections. Each section is energized by its own thyristor-controlled reactor (TCR), high voltage transformer, rectifier set bridge, and has its own hopper. The dust particles are removed from the collecting plates into receiving hopers [3]–[5]
