基于DTW度量和kNN分类器的核电多相无刷励磁系统旋转整流器故障诊断

A multiphase annular brushless excitation system is widely used in large-capacity nuclear power units. Accurate fault diagnosis of the rotating rectifier is of great significance to improve the reliability of the excitation system. However, the traditional diagnosis method based on the harmonic analysis of stator field current has some deficiencies. In this article, a novel diagnosis method using ...
