Analysis of Thermo-Mechanical Stress in Fiber Bragg Grating Used for Hydro-Generator Rotor Temperature Monitoring

Journal of Microwaves, Optoelectronics and Electromagnetic Applications
Fiber Bragg gratings (FBGs) offer new possibilities to monitor accurately the rotor temperature. Dozens of sensors can be mounted in series in a single fiber and used to measure the temperature in several points of the rotor winding.

Identification and Evaluation of Vibration Sources from Experiments on Laboratory Drilling Equipment

Machines
Rotary rock drilling generates vibration signals that capture the dynamic behavior of the drilling system, the interaction between the tool and the rock, and the progression of tool wear. These signals, traditionally considered undesirable, have become a

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 ...

A digital governor for hydrogenerators

IEEE Transactions on Energy Conversion, 1988
The authors describe the development and testing of a microcomputer-based digital governor for hydrogenerators. The digital governor was shown to approximate the control function of existing analog controllers. This task was performed as a first step to future work intended to utilize the versatility of microcomputers in effecting more sophisticated ...
