This paper discusses the application of MultiLayer Feed Forward Neural Network (MFNN) for the differential protection of the turbogenerator based on pattern classification. The cases of all the possible internal faults in the stator of the generator with lap winding have been simulated using Modified Winding function Approach. The simulated fault currents in the phases and their parallel paths ...

On-line estimation of variable parameters of synchronous machines based on a novel adaptive algorithm is presented. The estimation process involves instantaneous parameter tracking and subsequent data processing. The variable parameters are ultimately expressed as nonlinear functions of operating conditions. On-line estimation process is applied to a IOOMVA turbogenerator. While this paper deal...

The paper deals with the determination of synchronous machine parameters using a 2D Finite Element Method – FEM (Flux2DCedrat). Simulations of no-load sudden three phase shortcircuits are performed in rotation, the saturation effects and the eddy currents in the rotor solid iron parts are also taken into account. Comparisons between calculations and measurements for two large existing units (tu...

in this paper, the probable methods of generating electrical power by using different methods and different sources of energy in year of 1990 -2000 are examined , the initial capital costs and reliability of the methods are compared with the conventional turbogenerator. this particular time may not be sufficient to explor the new ideas, but is enough to complete the known methods. it seem that,...

Power system stabilizers (PSS) play an important role in damping of power system oscillations. An intensive research activity has been devoted to design of their structure and optimal setting of their parameters. In this paper the simultaneous optimization of multiloop PSS and automatic voltage regulator parameters (AVR) by means of genetic algorithm is proposed. Using an example of the 259 MVA...

This article introduces the theory behind digital order tracking, which is implemented by oversampling, interpolation and resampling techniques in Brüel&Kjær instrumentation. As application examples order tacking is applied to the vibration signal from a coast down of a turbogenerator from a power plant station, a run-up of a large marine diesel engine, gated measurement on an automobile engine...

This paper presents the design of two separate Continually Online Trained (COT) Artificial Neural Network (ANN) controllers for excitation and turbine control of a turbogenerator connected to the infinite bus through a transmission line. These neurocontrollers augmentheplace the conventional automatic voltage regulator and the turbine governor of a generator. A third COT ANN is used to identify...

This paper presents a unique flywheel-based regenerative energy recovery, storage and release system developed at the author’s laboratory. It can recover and store regenerative energy produced by braking a motion generator with intermittent rotary velocity such as the rotor of a wind turbogenerator subject to intermittent intake wind and the axels of electric and hybrid gas-electric vehicles du...
