Assessment of the accuracy of synchronous generator model

After completion of the estimation process, the filtered waveforms were practically the same as the simulation ones. The parameter estimation was performed for a turbogenerator with the ratings: This page was last edited on 17 Decemberat It is convenient to transform the stator voltages and currents to the Park generatkr coordinate system. 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.

Should you be interested in starting a co-operation with DFME please contact us – e-mail: It is shown in Fig. A gradient algorithm with constraints from the Optimization Toolbox for Matlab was used for the minimization of the objective function.

To avoid additional estimation errors caused by the abovementioned disturbance components, the measurement signals should be filtered. I am responsible for the concept, design, programming and development.

Some of the words may be incorrectly translated or mistyped. They do not provide a constant group delay, however it is possible to design a filter with a maximally flat amplitude characteristic in the passband. Finally the vapour is condensed back to a liquid and fed back in the pump.

Schematic diagram of zero-phase filtering 0.

Synchronous motors in standard or Ex design Exp, Exn, Exe used as drives for fans, pumps, mills, compressors, mixers, belt conveyors and other industrial equipment. 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.

The waveform of errors calculated according to 2 is shown in Fig. Under normal operating conditions, the value of the generator stator resistance does not influence the waveforms of electrical quantities significantly. The following other wikis use this file: Retrieved from ” https: Even a small noise in the waveforms is strongly amplified when calculating derivatives. Polish – English Results for: Date 29 November Source Rankine cycle layout.

Sometimes you can find translation results directly from Google by typing: 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.

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. When analyzing symmetrical transient states of the generator for which the stator star point is non-grounded, there is no zero-sequence component. Two-pass recursive gemerator filter with zero phase shift.

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]. Of the parameters, the most difficult to determine are the stator resistance and the subtransient reactance in the q generatkr, independently of the filter used in the investigations.

Generayor 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.
