Dekoder nemoduliranega signala IRIG-B

KOVAČIČ, ALJAŽ (author), Jankovec, Marko (mentor)

V magistrski nalogi je predstavljeno načrtovanje dekoderja signala IRIG-B, pogosto uporabljenga protokola za časovno sinhronizacijo naprav. Dekoder bo umeščen v merilno napravo PMU (Phasor Measurement Unit), ki se uporablja za oceno stanja elektroenergetskega omrežja. Predstavljeno je tudi ozadje naprave PMU in vloga časovne sinhronizacije pri njenem delovanju. Prikazani so rezultati vrednotenja izdelanega dekoderja. Dekoder se dobro obnese pri dekodiranju vhodnega signala ter, zahvaljujoč implementiranim mehanizmom za odkrivanje napak, ne podaja napačne informacije. Pri generiranju izhoda je prisotna prevelika zakasnitev glede na prožilni signal.

Abstract

The thesis describes an implementation of an IRIG-B decoder. IRIG-B is a commonly used time synchronization protocol. The decoder will be fitted to a device called PMU (Phasor Measurement Unit), used to assess the state of the power grid. The significance of the PMU is explained and also the importance of time synchronization for its working. The results of the evaluation of the constructed decoder is presented. The decoder performs well at decoding the input signal and with the use of several implemented error checking mechanisms does not provide an incorrect data. There is however, too large of a delay present in the output signal compared to the trigger signal.
