Automatic System for Failure Detection in Hydro-Power Generators

Loss of Excitation Faults Detection in Hydro- Generators Using an Adaptive Neuro Fuzzy Inference System

This paper presents a new approach for Loss of Excitation (LOE) faults detection in Hydrogenerators using Adaptive Neuro Fuzzy Inference System. The proposed scheme was trained by data from simulation of a 345kV system under various faults conditions and tested for different loading conditions. Details of the design process and the results of performance using the proposed technique are discuss...

Modelling and Simulation of Low-Head Hydro Turbine for Small Signal Stability Analysis in Power System

The hydro turbine dynamics have a considerable influence on the dynamic stability of power system. In the study of dynamic stability, the system is modeled by the linear differential equations (small  signal analysis). Small signal stability of power systems is needed in all conditions and only is dependent on the conditions of power system performance before commotion occurrence. This paper pr...

Power Conversion System for Grid Connected Micro Hydro Power System with Maximum Power Point Tracking

An Innovative Inductive Air-gap Monitoring System for Large Low Speed Hydro-generators, Tests in Operation

Large low speed hydro-generators (fig. 1) have a very small specific air-gap to stator bore diameter ratio making it virtually impossible to have a perfect centering of the rotor within the stator during the assembly process. Therefore the machines are operated with an eccentricity that, though small, is not negligible, and is the cause of undesirable effects: considerable unbalanced magnetic p...
