Spectral Analysis of Power Quality of Asynchronous Thyristor Loading Device

Abstract

The paper presents an investigation aimed at exploring the power quality of asynchronous thyristor loading device. In the process of work the simulation model of asynchronous thyristor cascade was created. Then software to calculate it was developed. Spectrogram of current for power quality analysis and three-dimensional dependencies diagram of distortion of the angle of opening thyristor and engine speed were built.
