Abstrakt
PLC on ennast hästi tõestanud, olles kõige laialdasemalt kasutatav andmeside tehnoloogia
Euroopas. Seetõttu on vajalik PLC tehnoloogia pidev arendamine, mis võtaks arvesse
tehnoloogilisi muutusi, vajadusi ja võimalusi ning oleks pikemas perspektiivis kergesti
kohandatav ja keskkonnasõbralik. Töö eesmärk on välja selgitada G3-PLC tehnoloogial
põhineva kontsentraatori andmete kogumise eelised võrreldes varasema G1-PLC
tehnoloogiat kasutava kontsentraatoriga. Antakse ülevaade kauglugemissüsteemist ja
selgitatakse PLC elektriarvesti ning andmekontsentraatori tööpõhimõtet. Kirjeldatakse
kahe erineva generatsiooni andmekontsentraatori funktsionaalsust, paigaldamise ja
konfigureerimise aluseid ning seletatakse kauglugemissüsteemi, andmekontsentraatori ja
arvesti vahelise suhtlemise põhimõtteid toetudes kirjadusallikatele ning autori
töökogemusele. Analüüsist järeldub, et G3-PLC tehnoloogial põhinev kauglugemissüsteem
on stabiilne ning võimeline töötama erinevates tingimustes. Kuna G3-PLC DC450 kasutab
OFDM sagedustihendust, siis võimaldab see andmeid edastada kiiremini kui CENELEC A
sagedusala kasutav varasema generatsiooni kontsentraator. Teiste riikide poolt läbiviidud
pilootprojektide tulemustest järeldab autor, et G3-PLC tehnoloogiat kasutavad seadmed
võiks võtta kasutusele ka Eestis. See aitaks vähendada probleeme peamiselt alajaamades,
kus võrgus esinev müra takistab signaali levimist ning seetõttu on häiritud tarbimisandmete
edastamine kauglugemissüsteemi.
PLC has indeed proven itself, being the most widely used data communication technology in Europe. Hence, it is necessary to develop the PLC technology constantly. It should consider contemporary technological needs and opportunities and be easily adaptable as well as environmentally friendly in the longer run. The aim of the work is to ascertain the advantages of data communication of a concentrator based on the G3-PLC technology as compared to the former concentrator operating with the G1-PLC technology. The paper provides an overview of an automated meter reading system and explicates the principles of a PLC electricity meter and a data concentrator. Furthermore, the functionality and the bases of installation and configuration of data concentrators of two different generations are outlined in the thesis. Also, the principles of communication between an automated meter reading system, a data concentrator, and a meter are explained according to literary sources and the author`s work experience. From the analysis, it can be concluded that the automated meter reading system based upon the G3-PLC technology is stable and capable of functioning in various conditions. As the G3-PLC DC450 uses OFDM, it is possible to transmit data faster in comparison with an earlier version of a concentrator based on the PLC technology that employs CENELEC A frequency range. From the pilot projects conducted by other countries, it is deduced that devices based on the G3-PLC technology could be applied in an automated meter reading system in Estonia, too. It would help to reduce problems primarily in substations, where noises impede the signal in the network, and thus the transmission of consumption data is disturbed.
