Assessment of the accuracy of synchronous generator model

Date 29 November Source Rankine cycle layout. After completion of the estimation process, the filtered waveforms were practically the same as the simulation ones.

Akademicka 10, Gliwice, E-mail: Although EUdict can’t translate complete sentences, it can translate several words at once if you separate them with spaces or commas.

Those waveforms were disturbed with Gaussian noise with zero mean value, thus approximately simulating the real measurement signals.

There is a way to enable word translation from any page: It can result in errors arising in the process of electromagnetic parameter estimation of a synchronous generator.

Documents Flashcards Grammar checker. Filtration of the waveforms Three-phase voltages and currents of the stator of frequency 50 Hz as well as the field voltage and excitation current were the measured electrical quantities of the generator.

Schematic diagram of zero-phase filtering 0. This licensing tag was added to this file as part of the GFDL licensing update. Synchronous motors used as drives for hoisting machines in coal, metal ore and other mining industries. I do this in my spare time. The voltages and currents of the stator in the dq0 coordinate system as well as the field voltage and excitation current contain mainly a constant component.

Should you be interested in starting a co-operation with DFME please contact us – e-mail: Synchronous motors in standard or Ex design Exp, Exn, Exe used as drives for fans, pumps, mills, compressors, mixers, belt conveyors and geherator industrial equipment. A bookmarklet is a small JavaScript code stored as a bookmark in you browser. Results of electromagnetic parameter estimation The parameter estimation of the generator model in the d and q axes was performed for the waveforms shown in Figs.


The measured waveforms of voltages and currents are additionally distorted by a rectifier in the excitation winding circuit, a salient pole rotor as well as the slotting of stator and generatir cores.

Smaller estimation errors were obtained for the Butterworth filter. Application of the stationary DC decay test to industrial turbogenerator model parameter estimation. Zero-phase filtering provides elimination of the effect of the filter phase response on the signal phase angle, independently of the type of filtering. By using this site, you agree to the Terms of Use and Privacy Policy. Use of Pareto optimisation for tuning power system stabilizers. Using the filtered waveforms of the axial components of the stator and rotor currents and voltages as well as the waveform of the generator rotational speed, one can consider only the generator model in the estimation process, while the other elements of the generating unit can be omitted.

Look at the complete list of languages: Moreover, the signal synhcroniczny sequence is reversed twice in this filtration. These dictionaries are the result of the work of many authors who worked very hard and finally offered their product free of charge on the internet thus making it easier to all of us to communicate with each other. It was assumed that the disturbance was a small additional component in the form of a step change or a pseudorandom signal PRBS introduced to the voltage regulator reference voltage Vref.

Filtered and simulation output waveforms in the first iteration step for a disturbance in the form of the Synchronicznh signal 0.

For estimation there was used the least squares method by defining the following objective function [7, 9]: This property is important when there are variations in the power system frequency in transient states. Increase in the order of the filter results in a simultaneous increase in the steepness of the amplitude characteristic in the stopband and flattening this characteristic in the passband [17].

It was also assumed that synhroniczny generator was operating in a synchroniczng power system PS under a load close to the rated one [7,10,11]. In Chrome, first click on a language synchronczny and change the search keyword in the field ‘Keyword’ to a keyword eg: Disturbances in signals are the result of the measuring environment, as well as the presence of machines and electrical devices current channels, drives, transformersand converter systems diodes, thyristors.
