20.500.12556/DKUM-99482 Vodenje mehanizma prehoda za vodne organizme na Jezu Markovci Control of the aquatic organism passage mechanism at the Markovci Dam V diplomski nalogi je predstavljen razvoj sistema za vodenje zapornice ribjega prehoda na jezu Markovci v sklopu hidroelektrarne Formin. Sistem je bil razvit v programskem okolju TIA Portal za programirljivi logični krmilnik Siemens. V nalogi so predstavljeni tudi uporabljena krmilna oprema, periferne naprave in komunikacijska infrastruktura. V okviru razvoja so bile izvedene obdelava analognih meritev, vodenje zapornic, implementacija alarmnega sistema ter vzpostavitev komunikacije s procesnim sistemom PCS7. Programska rešitev je bila zasnovana modularno in razdeljena na funkcionalne bloke, kar omogoča preglednost, lažje vzdrževanje in nadaljnjo nadgradnjo sistema. Implementirana sta bila ročni in avtomatski način obratovanja ter ustrezne varnostne funkcije za zanesljivo delovanje. Pravilnost delovanja sistema je bila preverjena s simulacijo, rezultati pa potrjujejo, da rešitev zagotavlja stabilno regulacijo pretoka, nemoteno delovanje prehoda za vodne organizme ter omogoča učinkovit daljinski nadzor in upravljanje. The thesis presents the development of a system for controlling the aquatic organism passage gate at the Markovci dam as part of the Formin hydroelectric power plant. The system was developed in the TIA Portal programming environment for the Siemens programmable logic controller. The thesis also presents the control equipment, peripheral devices and communication infrastructure used. The development included processing of analog measurements, gate control, implementation of an alarm system and establishment of communication with the PCS7 process system. The software solution was designed modularly and divided into functional blocks, which allows for transparency, easier maintenance and further upgrading of the system. Manual and automatic operating modes and appropriate safety functions for reliable operation were implemented. The correct operation of the system was verified by simulation, and the results confirm that the solution ensures stable flow regulation, smooth operation of the passage for aquatic organisms, and enables effective remote monitoring and control.
