POWER QUALITY MEASUREMENT ANALYSIS OF THE ELECTROSTATIC PRECIPITATOR

Aleksandar Nikolic, Ilija Stevanovic

Abstract

Power quality measurement analysis of the electrostatic precipitator in thermal power plant under different working conditions is presented in the paper. Control of electrostatic precipitator is realized by digitally controlled antiparallel thyristors. In the first regime (continual) the constant firing angle of thyristor is set in dependence of the reference current. In other regime (intermittent) the ON/OFF period is set. For both control strategies the measurement of the content of higher harmonic of voltage and current is performed. Analysis of the measured results is done according to the methodology based on EU power quality standard EN 50160. The plant under investigation is electrostatic precipitator in the largest thermal power plant "Nikola Tesla A" in Serbia, but the obtained results could be used for any similar power plant.
