Although EUdict can’t translate complete sentences, it can translate several words at once if you separate them with spaces or commas. The most common way is by word input you must know which language the word is in but you can also use your browser’s synchronicany box and bookmarklets or favelets.

Separating magnets and electromagnetic separators used to remove ferromagnetic elements and impurities from non-magnetic material carried on belt conveyors in mining, food and power industry. That is why a low-pass filter was used for filtration of the noisy waveforms.

In the investigations, there was assumed that the dynamic waveforms caused by a small disturbance of the voltage regulator reference voltage in the form of a step change or a pseudorandom signal PRBS Pseudo Random Binary Sequence are the basis of parameter estimation [10]. Wide range of offered basic technical parameters such as output, voltage, rotating speed and number of pole pairs.

To add EUdict alongside Google, Yahoo! 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].

Induction motors squirrel cage motors, double speed squirrel cage motors, slipring motors, asynchronous synchronized motors in standard or Ex design Exp, Exn, Exe used as drives for fans, pumps, mills, compressors, mixers, belt conveyors and other industrial equipment. The signals used for parameter estimation of the synchronous generator model 0. Siemens Power Technologies Inc. Documents Flashcards Grammar checker. Noisy waveforms of the stator voltages and currents in the d and q axis as well as the generator field voltage and excitation current when disturbing the machine steady operation with a PRBS signal 18 0.

The waveforms of the electrical quantities of the stator were expressed in generator relative units, while those of the rotor in regulator relative units [14].

It aims at restoring the original order of the samples. In Chrome, first click on a language pair and change the search keyword in the field ‘Keyword’ to a keyword eg: Those waveforms were disturbed with Gaussian noise with zero mean value, thus approximately simulating the real measurement signals.

Retrieved from ” https: These harmonics as well as their effect on the magnetic flux are not taken into account in classical mathematical models. FIR filters can be designed to be linear-phase.

Polish – English Results for: Two-pass recursive digital filter with zero phase shift. 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.

Synchronous generators driven by diesel engine for continuous duty or standby power supply in local or industrial power plants, including biomass-fired plants. You may do so in any reasonable manner, but not in any way that suggests the licensor endorses you or your use. Let me take this chance to thank all who contributed to the making of these dictionaries and improving the site’s quality:.

In the next stage of calculations, the waveforms filtered with the use of a FIR filter designed using the time window method were the basis of estimation.

Vdi, Vdin — instantaneous values of the filtered and non-noisy voltage n of the generator stator in the d axis. In the paper, there are presented the results of parameter estimation of the mathematical model of a synchronous generator operating in a single-machine power system. DFME – generators and electric motors Here at DFME, we offer complete solutions for the design, manufacture and servicing of medium and large electric machines of any type, drawing on our many years of experience in this area.

The vapour expands through the turbine dropping significantly in pressure and temperature to state 4.

Mechanical energy, rotation of ysnchroniczny rotor, is transformed to electrical energy into Gfnerator Generator. If you are searching for a word in the Chinese dictionary and not receiving any results, try without Pinyin term in brackets.

Zero-phase filtering provides elimination of the effect of the filter phase response on the signal phase angle, independently of the type of filtering. If you are searching for a word in Japanese Kanji dictionary and not receiving any results, try without Kana term in brackets.

The least squares method was used for parameter estimation, and the gradient method was applied to minimization of the mean square error.

Assessment of the accuracy of synchronous generator model

Online estimation of synchronous generator parameters using PRBS perturbations. For estimation there was used the least squares method by grnerator the following objective function [7, 9]: Views View Edit History.

It was also assumed generaor the generator was operating in a single-machine power system PS under a load close to the rated one [7,10,11]. From Wikimedia Commons, the free media repository. Schematic diagram of the generating unit operating in a single-machine PS The introduced disturbance resulted in changes of the waveforms of: Synchroniczmy should be noted that the stator resistance of high power synchronous generators is small compared to the synchronous resistance.

Date 29 November Source Rankine cycle layout.

Even a small noise in the waveforms is strongly amplified when calculating derivatives. 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.

Assessment of the accuracy of synchronous generator model

Heat is added in the boiler by the burning of fuel although heat can be added by any method boiling the fluid to state 3. Exemplary waveform of errors resulting from filtration of the stator voltage in the d axis Ifd, p.

DC motors used as drives for hoisting machines in coal, metal geneator and other mining industries.
