Abstract
U radu je razvijeno sklopovlje i programska potpora mjernog sustava za kontinuirano praćenje strujno-naponskih odnosa u gradskoj mreži. Sustav omogućuje mjerenje efektivne vrijednosti struje i napona te mjerenje faznog odnosa između tih dviju veličina. Mjerni sustav temeljen je na mikrokontroleru STM32H745 za upravljanje periferijskim sklopovljem i obradu signala, strujnom senzoru ACS725 i mjernom transformatoru ZMPT107-1. U sustav je uključen dodatni mikrokontroler ESP8266EX koji služi za... More povezivanje sustava s Wi-Fi mrežom i prikaz mjernih rezultata putem lokalnog web servera, a s glavnim mikrokontrolerom se povezuje putem UART komunikacijskog protokola. Provedena je eksperimentalna verifikacija mogućnosti mjernog sustava te je pokazano da su nesigurnosti mjerenja napona, struja i faznog kuta među njima unutar očekivanih granica. Less
Abstract (english)
In this thesis the hardware and software needed for a measurement system for continuous monitoring of current and voltage relationships in electrical power grid was developed. The system enables the measurement of current and voltage RMS values and the measurement of the phase relationship between these two values. The measuring system is based on the STM32H745 microcontroller for peripheral control and signal processing, ACS725 current sensor, and ZMPT107-1 measurement transformer. The... More system includes an additional microcontroller ESP8266EX, which is used to connect the system over a Wi-Fi network and to display measurement results via a local web server. The additional microcontroller is connected with the main microcontroller via a UART communication interface. An experimental verification of the measuring system capabilities was performed and it was shown that the measurement uncertainties of the voltage, current and phase angle measurements are within the expected limits.
