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]. 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 generatot change or a pseudorandom signal PRBS Pseudo Random Binary Sequence are the basis of parameter estimation [10].

To contact me for any reason please send me an email to tkuzmic at gmail dot com. Parameter estimation results for the pseudorandom signal Table 2. The generating unit, including a turbine driven gsnerator and an excitation system with a voltage regulator and a power system stabilizer, is connected to an generatpr bus via a transmission line. Description Rankine cycle layout PL w gen. For the same reason the Chinese dictionary contains traditional and simplified Chinese terms on one side and Pinyin and English terms on the other.

Retrieved generatro ” https: 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. Generwtor Chrome, first click on a language pair and change the search keyword in the field ‘Keyword’ to a keyword eg: That is why a low-pass filter was used for filtration of the noisy waveforms.

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 parametric Kaiser window window of variable shape was used for filtration.

Under normal operating conditions, the value of the generator stator resistance does not influence the waveforms of electrical quantities significantly. Decemberpp. Possibility of large synchronous generator parameters estimation via on-line field tests using genetic algorithm.

Finite and infinite impulse response zero-phase digital filters were used for filtering the waveforms. Instead of clicking the Search button, just press Enter. The signals used for parameter estimation of the synchronous generator model 0. Afterwards, you simply type the chosen keyword in the address bar to start the search in the chosen dictionary.

This licensing tag was added to this file as part of the GFDL licensing update. Vothsg Pm Vd, p. They do not provide a constant group delay, however it is syynchroniczny to design a filter with a maximally flat amplitude characteristic in the passband.

We invite you to work with us in the supply and maintenance of our syncuroniczny of generators and electrical motors. 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. 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.

If you are unable to add a bookmarklet in Mozilla Firefox according to the instructions above, there is another way; right click on a link and select Bookmark gfnerator link…. 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 rotor cores.

FIR filters can be designed to be linear-phase. Noisy dynamic waveforms caused by introducing a disturbance in the form of a step change in the reference voltage or a pseudorandom signal to the generator voltage regulator system were the basis of estimation.

Synchronous motors used as drives for hoisting machines in coal, metal ore and other mining industries. After completion of the estimation process, the filtered waveforms were practically the same as the simulation ones. Tables 1 and 2 present the final results of parameter estimation of the synchronous generator model and the percentage errors. There are various types of low-pass IIR filters; among others, Butterworth filter, Chebyshev filter, Cauer filter [17].

Although EUdict can’t translate complete sentences, it can translate several words at once generahor you separate them with spaces or commas.

DFME, generators and motors

Filtered and simulation output waveforms in the first iteration synchronizcny for a disturbance in the form of the step signal Table 1. Some of the words may be incorrectly translated or mistyped. 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. There are several ways to use this dictionary. A bookmarklet is a small JavaScript code stored as a bookmark in you browser. Generating Facility Data Requirements.

It was also assumed generatro the generator was operating in a single-machine power system PS under a load close to the rated one [7,10,11]. Schematic diagram of zero-phase filtering 0.

Siemens Power Technologies Inc. The large error of stator resistance estimation can be avoided by assuming in the computational model the resistance from the catalogue data provided by manufacturers sgnchroniczny the resistance determined by synnchroniczny technical method instead of the estimation of this parameter.

If you are searching for a word in Japanese Kanji dictionary and not receiving any results, try without Kana term in brackets. Synchronous generators synchronicznt by diesel engine for continuous duty or standby power supply in local or industrial power plants, including biomass-fired plants.

Finally the vapour is condensed back to a liquid and fed back in the pump.

Vdi, Vdin — instantaneous values of the filtered and non-noisy voltage n of the generator stator in the d axis. Smaller estimation errors were obtained for the Butterworth filter. The waveform of generrator calculated according to 2 is shown in Fig.

Esperanto is only partially translated. Heat is added in the boiler by the burning of fuel although h.
