20.500.12556/DKUM-43447 POSODOBITEV KRMILJENJA IN DALJINSKI NADZOR ČRPALIŠČA ZA HIDROELEKTRARNO DRAVOGRAD RENEWAL AND REMOTE CONTROL OF HYDROELECTRIC POWER PLANT DRAVOGRAD PUMPING STATION V magistrski nalogi je zajeta in opisana prenova sklopa krmiljenja črpališča Črneče Hidroelektrarne Dravograd. Sklop krmiljenja črpališča Črneče je v obratovanju že 20 let in je bil izveden z relejsko logiko brez prikazovalnika povratne informacije o stanju črpalk, stanju bazena in prikazov alarmov. Zaradi iztrošenosti ter težav pri prenosu signalov (fizično prekinjene žile kablov zaradi lezenja terena med bazenom Dobrova in črpališčem Črneče) smo se odločili zamenjati krmiljenje in avtomatizirati sistem na višji nivo (funkcionalnost sistema je ostala nespremenjena). Komunikacijsko težavo smo odpravili z vpeljavo usmerjene telemetrične zveze prek radijskih postaj Motorola DM-3400. Krmiljenje pa je izvedeno s Siemens SIMATIC opremo. This master thesis covers and describes the renewal of the Dravograd hydroelectric power plant’s Črneče pumping station controlling equipment set. The Črneče pumping station controlling equipment set has already been in operation for 20 years and its controlling has been executed using the relay logic with no pump condition, tank condition or alarm review feedback display. Due to wear and tear and problems with signal transmissions (physically disconnected cables because of creep between the Dobrova tank and the Črneče pumping station) we've decided to replace the controlling equipment and automate the system to a higher level (the system's functionality has remained unchanged). We've eliminated the communication problem by establishing a directed telemetry connection through radio stations Motorola DM-3400, while we used the Siemens SIMATIC equipment for controlling. daljinski nadzor brezžična komunikacija krmiljenje nivoja črpališča PLK STEP7 remote control wireless communication pumping station level controlling PLC STEP7 true true false [J.
