САЖЕТАК / ABSTRACT:
U radu je dat prikaz Off-Grid napajanja hidrometeoroloških stanica (HMS) u sistemu za prikupljanje i praćenje meteoroloških podataka duž plovnog puta reka Dunav i Sava na teritoriji Republike Srbije. Off-grid napajanje je u osnovi bazirano na fotonaponskom panelu snage 415W, bateriji 12Vdc/265Ah i odgovarajućem kontroleru punjenja sa implementiranom funkcijom praćenja tačke maksimalne snage fotonaponskog panela (MPPT kontrola). Potrošači u sistemu za prikupljanje i praćenje meteoroloških podataka su: meteorološka stanica sa pripadajućim senzorima (smer i brzina vetra, temperatura vazduha, relativna vlažnost, vazdušni pritisak i količina padavina), senzor vidljivosti, senzori pritiska i temperature vode u reci, komunikacioni interfejs sa uređajem za detekciju i merenje prisustva i karakteristika rečnih talasa (plutajuća bova), PLC kontroler kao koncentrator podataka i ostali telekomunikacioni uređaji za komunikaciju sa nadzornim komandnim centrima. Napajanje električnom energijom sistema HMS obezbeđuje pouzdano i besprekidno napajanje pomenute merne i komunikacione opreme u širokom opsegu temperatura okoline (-40 °C do +60 C°), pri nepovoljnim vremenskim uslovima, atmosferskim uticajima (kiša, sneg, vlaga) kao i uticajima atmosferskih pražnjenja koja su veoma učestala duž pomenutih rečnih tokova. Stoga je u radu dodatno istaknuta uloga i načini realizacije kako primarne zaštite oda atmosferskih pražnjenja (udara groma), tako i sistema sekundarne prenaponske zaštite merne i telekomunikacione opreme.
