Fault detection algorithm used in a magnetic monitoring system of the hydrogenerator
, 2022 In this study, the authors propose a fault detection algorithm used in an on-line magnetic monitoring system in the hydropower plant. The proposed algorithm is based on two magnetic measuring methods: measurement of (inner) flux within generator in air ...

Nonlinear Vibration Analysis of Rotor considering Cogging and Harmonic Effects
Shock and Vibration, Volume 2021, Issue 1, 2021., 2021 This paper aims to investigate nonlinear vibration characteristics of rotor system considering cogging and harmonic effects. Firstly, relative permeance with eccentric was established and then corrected by correction factor caused by the cogging effect.

Mathematical Problems in Engineering, Volume 2021, Issue 1, 2021., 2021 This paper investigates the effect of the field winding interturn short‐circuit (FWISC) position on the rotor vibration properties in turbo generators. Different from the previous studies which focused on the influence of the short‐circuit degree, this work pays much attention to the impact of the short‐circuit position on the rotor unbalanced magnetic
