Abstract

Outdoor SVG (container-type) is especially suitable for limited space, such as old substations. The limited space of the entire device, and electromagnetic noise inside, especially that of the power chamber which is far higher than ordinary SVG. In the final analysis, the study on the law of change of SVG power chamber electromagnetic noise is the study on the law of change of IGBT current and voltage inside the power unit of the power chamber. Due to the complex structure of IGBT, the change of variants is usually nonlinear. Therefore, electromagnetic noise cannot be analyzed with common algorithms. In this paper, a method of differential mode and common mode electromagnetic noise spectrum calculation through analysis of dynamics of IGBT inside the power unit at different stages and derivation of law of change of current and voltage at different stages is introduced.
