In this paper steady state characteristic of a variable speed Doubly fed induction generator (DFIG) is investigated. Torque and speed is used as design parameters for DFIG. From mathematical model it is found that on increase of rotor injection voltage and resistance, the torque speed response is shifted from over synchronous to sub synchronous range. The stability of DFIG operation is entirely...
This paper presents a methodology for implementing artificial neural network (ANN) observers in estimating and tracking synchronous generator parameters from time-domain online disturbance measurements. Data for training the neural network observers are obtained through off-line simulations of a synchronous generator operating in a one-machine-infinite-bus environment. Nominal values of paramet...
Synchronous data-flow languages are used as design approaches in developing embedded and critical real-time systems in which synchronous programs are verified by applying formal verification. In a synchronous design approach, transformation and optimization are used to transform synchronous programs and generate general purpose executable code. The incorrectness of the transformations make the ...
Synchronous MPSoCs are widespread today, but the evolution of technology into the deep submicron domain leads to increasingly complex timing closure problems. One natural solution to these is to resort to the globally asynchronous, locally synchronous (GALS) paradigm. This work proposes a novel architecture for clock generators to support GALS systems. The generator can drive individual modules...
Wind energy, a kind of non-conventional energy source and environmental fresh energy, is widely studied nowadays. Directly driven wind turbine permanent magnet synchronous generator (D-PMSG) plays a vital role in the latest small-scale wind Power technology. This paper presents the modeling and simulation of a 12kW direct driven Permanent Magnet Synchronous Generator of Wind Power. This model c...
In this paper, a novel method is presented for detection and classification of the faultyphase/region in the stator winding of synchronous generators on the basis of the resulting harmoniccomponents that appear in the terminal voltage waveforms. Analytical results obtained through DecisionTree (DT) show that the internal faults are not only detectable but also they can be classified andthe rela...
In this paper, a PID fuzzy controller structure is presented. To be successful in implementing fuzzy PID controllers in large applications we must also considered their operating principles. Fuzzy logic controllers are based on empirical control rules. A study case for the validation of the proposed tunning mechanism is presented and analyzed with control application for a synchronous generator...
|Computer simulation of the operating characteristics of a three-phase brushless synchronous generator with self-exciter is presented. A voltage driven nonlinear time-periodic FEA is utilized to compute accurately the magnetic eld distribution and the induced voltages and currents simultaneously. A method for numerical modeling of the diodes is also discussed. First, the computation procedure i...
