Abstract
In all operating conditions, electrified sprinklers are provided with energy from a centralized source or a portable diesel generator. The energy efficiency of these power supply methods is characterized by losses of electricity during transmission. Battery power sources of sprinkler machines are used in rare cases, there are no such machines on the agricultural lands of the Volga region. If the battery power source is installed next to the electric drive on a support trolley, then there is no loss of electricity during transmission and there is the possibility of using renewable sources, the cost of electricity is close to zero. (Research purpose) The research purpose is in evaluating the increase in the energy efficiency of a sprinkler machine with a battery power source and renewable energy sources in comparison with traditional energy supply. (Materials and methods) Authors used theoretical and empirical methods of scientific knowledge, namely mathematical analysis, systematic approach, literature analysis, observation. (Results and discussion) The power consumption of irrigation systems fed the cable line from the centralized grid will consist of the energy consumed by the actuators support trucks irrigation systems and the energy consumed for transmission. The increase in the energy efficiency of a sprinkler machine with a battery power source in comparison with a cable line consists in saving energy for transmission. Found that when comparing the line cable from the battery feeding method should take into account the losses in transmission of energy along the entire length of the construction of irrigation machines and energy loss during transmission from the transformer substation to the fixed support irrigation systems. (Conclusions) The energy loss along the length of the sprinkler machine logarithmically depends on the number of sections. In relation to the operating conditions of sprinklers in the Saratov region, it is possible to reduce energy consumption even without taking into account the starting modes from 0.20 to 2.01 percent for water distribution by circular sprinklers.
