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

Improved hydrogenerator rotor thermal supervision
, 2023 The ongoing energy transition to cleaner energy involves three main changes: using less energy (energy savings on the demand side), making energy production more efficient, and using renewable and low-carbon sources instead of fossil fuels. However, relying more on intermittent renewable energy sources means we need to balance them with conventional ...
