Abstract
Diplomski rad obrađuje temu mjerenja električnih parametara niskonaponske mreže 230/400V, 50 Hz (struje, naponi, prividne, radne i jalove snage, faktora snage, radne i jalove energije) pomoću mikrokontrolera NXP LPC1768 s potrebnim periferijama za punu funkcionalnost. Mjerenje harmoničkog izobličenja je implementirano zbog sve češće pojave viših harmonika u niskonaponskoj mreži. Mjerenje električnih parametara temelji se na mjerenju prave efektivne vrijednosti tri struje i tri napona. Ostali parametri računaju se numeričkom obradom signala. Detaljno je opisan mjerni sustav kojeg čini analogno-digitalna pretvorba, numerička obrada signala, prikaz dobivenih veličina na samom modelu pomoću LCD-a te prikaz dobivenih veličina pomoću web poslužitelja.
Abstract (english)
The purpose of this master thesis is to present the implementation of an electrical parameters measurement system in a low-voltage network 230/400V, 50 Hz (currents, voltages, apparent, active and reactive powers, active and reactive energies) on NXP LPC1768 microcontroller with all the peripherals for full functionality. The measurement of Total Harmonic Distortion is implemented because of the more frequent occurrences of higher harmonics in low-voltage networks. The measurement of electrical parameters is based on the measurement of True Root Mean Square values of three currents and three voltages. The rest of the parameters are calculated by digital signal processing methods. The thesis includes a detailed description of a measuring system that consist of analog to digital conversion, digital signal processing, presentation of measured values on the model’s LCD module and presentation of measured values using a web server.
