ENERGY FLOW CONTROL IN COMBINED POWER SUPPLY SYSTEMS FOR AGRICULTURAL FACILITIES
The article proves the practicality of transferring individual objects of the agro-industrial sector to a combined power supply using a centralized network, photoelectric converters, and batteries. The authors state that there is no available information about the functioning algorithm of the combined power supply systems from foreign manufacturers and prove the necessity of independently developing and popularizing such systems. The article provides movement directions of energy flows in combined power supply systems. These areas offer the mutual redistribution of electrical energy between photovoltaic converters, batteries, consumers, and the industrial network. The authors show the prospects of developing the commercial supply of autonomously generated surplus electricity to the grid. The conditions for implementing the main directions of energy flows are formulated, and an algorithm for controlling the system elements is drawn up. The article presents the design of a basic relay-contact electrical circuit of the command-switching device of the combined power supply system. The authors describe the design of a semiconductor inverter ensuring the in-phase of the generated voltage with the industrial network voltage and present the block diagram of a command-switching device based on logical elements.
