A Decision Tree Approach for Steam Turbine-Generator Fault Diagnosis

Redundancy and inconsistency are universal features of the turbine vibration fault diagnosis. If we can provide a solution to the problem, it should be very meaningful that the fault diagnosis data included redundant and inconsistent information could be used to decision-making rules of fault diagnosis. A novel data mining approach for fault diagnosis of turbine generator unit is proposed based...

Effect of Different Turbine-generator Shaft Models on the Subsynchronous Resonance Phenomenon in the Double Cage Induction Generator Based Wind Farm

This paper focuses on the turbine-generator shaft models of double-cage Induction Generator (IG) based wind farm and its influence on the sub-synchronous resonance phenomenon. For this purpose, six different shaft models as 6-mass, 4-mass, 3-mass I, 3-mass II, 2-mass and 1-mass models are considered for double-cage IG wind-turbine. By using the linear modal analysis method, the effects of the d...

Prediction of unsteady loading on a steam turbine blade

A single rotor CFD model using wall-modeled Large Eddy Simulations (LES) was performed to predict the unsteady loading on the blade surface under partial admission. Geometry of the rotor blade of high pressure steam turbine of a 500 MW fossil-fuel power plant was used for this study. Periodically changing inlet boundary model was developed for single rotor model to simplify a full annular of th...

Steam Turbine Configuration

Most electric power is produced by steam turbines. This is because the steam cycle is well suited to the conversion of heat to work and steam turbines can be built in a wide range of capacities up to about 1500 MW. Steam turbines are basically very simple having fixed blades to accelerate the steam and moving blades to absorb the resulting kinetic energy. The moving blades are mounted on a rota...
