A Digital Twin Of A Power Supply For Electrostatic Precipitators Designed In MATLAB/Simulink

Abstract

Power supplies form a critical part of an electrostatic precipitator as it plays a crucial role in collection efficiency. Collection efficiency refers to the percentage of particulate matter removed from a gas stream as it passes through collecting plates. One problem associated with this power supply is a high voltage ripple that appears at the output of a transformer rectifier unit. To solve this problem a power supply that tends towards an idealistic peak to mean voltage ratio of unity is sought. The purpose of this study is to design a digital twin of a power supply for an electrostatic precipitator using MATLAB/Simulink software and analyze its performance. The characteristics of the output parameters of the transformer rectifier unit are obtained for a controlled firing angle. Its nominal data is presented where the performance of the model shows a peak to mean voltage ratio of 1.3. It is recommended to modify existing power supplies so that the voltage tends towards the idealistic peak to mean voltage ratio of unity to enhance collection efficiency.
