Daljinski Nadzor I Kontrola Hibridnog Postrojenja Za Navodnjavanje Useva Na Poljoprivrednoj Parceli U Mestu Belegiš

The paper presents the implementation of remote monitoring and control of a hybrid power plant for irrigation of crops on a private agricultural plot of about 10ha in the town of Belegiš. The hybrid irrigation system is based on the dominant use of renewable energy sources (RES), solar and wind, with the use of a strong 48V/1000Ah battery bank and a 7.5 kW dieselelectric generator as a back-up power source. The used irrigation pump is driven by a three-phase asynchronous electric motor with a power of 5.5 kW, which is supplied by a frequency regulator. Frequency regulation is used to pressure and flow control in the irrigation pipeline and provides additional efficiency of the system. As part of the system, all necessary elements of power electronics (solar and wind MPPT chargers, inverters and frequency regulator) have been implemented, which are networked together. The entire control system is based on a control module that controls the charging of the battery bank, controls the operation of the inverter, and acquires all the necessary measurements in the hybrid power supply system. Through the ETERNET port, this module is connected to the central computer that controls the operation of the entire hybrid plant. This computer is based on BEAGLEBONE BLACK processor. This module has the ability to receive and send data remotely via GSM/GPRS, a module through which it is possible to monitor all relevant parameters of the system, and it is also possible to remotely control of the irrigation system.
