Izdelava trifaznega kompleksnega števca električne energije

Stritih, Gašper (author), Begeš, Gaber (mentor)

Diplomska naloga opisuje postopek izdelave ter konfiguracije trifaznega kompleksnega števca električne energije, ki je namenjen za uporabo v gospodinjstvih na hišni elektroinštalaciji. Podatke o porabi energije nam prikazuje v živo na mobilno aplikacijo in na spletu Tako lahko vsak trenutek preverimo, kakšna je poraba gospodinjstva, in dostopamo do zbranih podatkov za pretekla obdobja. Števec je sestavljen iz treh modulov PZEM-004T-V3.0, mikroprocesorja ESP32 in napajalnika. Načrtovana je tudi tiskanina z nosilci za pritrditev v elektro omarico. Opisana je potrebna konfiguracija modulov PZEM ter obravnavana namestitev programske opreme ESPHome in Home Assistant za pravilno delovanje števca in prikaz podatkov. Izdelani merilnik je bil na koncu preizkušen v laboratoriju na fakulteti in primerjan s podobnim merilnikom, ki je dobavljiv na trgu.

• Title: Development of a three-phase complex electricity meter

Abstract

The thesis describes the development process and configuration of a three-phase complex electricity meter, which is intended for use in households on the house electrical installation. It shows us electricity consumption data live on the mobile application and on the Internet. Thus, we can check the household consumption at any moment and have collected data for past periods. The electricity meter consists of three PZEM-004T-V3.0 modules, an ESP32 microprocessor and a power supply. A printed circuit board with brackets for attaching it in the electrical panel is also designed. Furthermore, the thesis describes the necessary configuration of PZEM modules and the installation of the ESPHome and Home Assistant software for the correct operation of the meter and data display. The produced meter was finally tested in the laboratory at the college and compared with a similar meter available on the market.
