Moreover, the signal time sequence is reversed twice in this filtration. This is done at the expense of the amplitude characteristic slope in the transition band between the pass and stopbands. Synchronous generators driven by diesel engine for continuous duty or standby power supply in nuclear power generattor.

Siemens Power Technologies Inc. Parameter estimation results for the pseudorandom signal Table 2.

Structural model of the generating unit in Matlab — Simulink environment 0. The excitation system with the voltage regulator and power system stabilizer and the turbine with its governor influenced these waveforms. Finite and infinite impulse response zero-phase digital filters were used for filtering the waveforms.

Synchronous permanent magnet DOL motors used as drives for fans, pumps, mills, compressors, mixers, belt conveyors and other industrial equipment.

Each filter introduces a phase shift unwanted from the point of view of parameter estimation. The waveform of errors calculated according to 2 is shown in Fig.

The generating unit, including a turbine driven generator and an excitation system with a voltage regulator and a power generztor stabilizer, is connected to an infinite bus via a transmission line. It was assumed that the ratio of the power spectral density of particular signals except the generator field voltage to the noise power spectral density SNR — Signalto-Noise Ratio was equal to 35 dB.

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

DFME, generators and motors

Even a small noise in the waveforms is strongly amplified when calculating derivatives. We invite you to work with us in the supply and maintenance of our range of generators and electrical motors. 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.

Vothsg Pm Vd, p. If you want to type a character which isn’t on your keyboard, simply pick it from a list of special characters. To illustrate the differences between the non-noisy waveform and the filtered one, there was introduced a percentage error waveform defined by the formula: Zero-phase filtering provides elimination of the effect of the filter phase response on the signal phase angle, independently of the type of filtering.

It aims at restoring the original order of the samples. The signals used for parameter estimation of the synchronous generator model 0. There are two main groups of these methods: 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.

Please help us improve this site by translating its interface.

Smaller estimation errors were obtained for the Butterworth filter. Decemberpp. 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.

Documents Flashcards Grammar checker. Possibility of large synchronous generator parameters estimation via on-line field tests using genetic algorithm. 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.

Some of the words may be incorrectly translated or mistyped. 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. Generating Facility Data Requirements. Exemplary waveform of the armature? Although EUdict can’t translate complete sentences, it can translate several words at once if you separate them with spaces or commas.

Sometimes you can find translation results directly from Google by typing: Tables 1 and 2 present the final results of parameter estimation of the synchronous generator model and the percentage errors. Filtered and simulation output waveforms in the first iteration step for a disturbance in the form of the step signal Table 1. These harmonics as well as their effect on the magnetic flux are not taken into account in classical mathematical models.

Zwykle zastosowany jest generator synchroniczny. There was examined the influence of a type and parameters of the filter used on the electromagnetic parameter estimation results of the generator model.

There are several ways to use this dictionary. It is convenient to transform the stator voltages and currents to the Park dq0 coordinate system. It can be seen that the maximum error is small because it does not exceed 0.

FIR filters can be designed to be linear-phase. Of the parameters, the most difficult to determine are the stator resistance and the subtransient reactance in the q axis, independently of the filter used in the investigations.

It can result in errors arising in the process of electromagnetic parameter estimation of a synchronous generator. If you are unable to add a bookmarklet in Mozilla Firefox according to the instructions above, there is another way; synchroniczn click on a link and select Bookmark this link…. Perhaps the best way to enable dictionary search is through integration into the search field of your browser.

Butterworth filters Noisy Filtered Non-noisy 0. 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.
