AUTONOMOUS POWER SUPPLY OF SPRINKLER EQUIPMENT THROUGH THE USE OF A MICRO-HYDROPOWER STATION

Abstract

Purpose: to assess the potential for the functional implementation of a micro-hydropower station in the design of a sprinkler machine to meet the in-system needs for electrical energy. Materials and methods: the study was carried out on the basis of an example of calculating the installation of a micro-hydropower station by A. G. Chernykh and the formulas presented in the handbook on hydraulics. To construct the multiple regression equation, the inverse matrix solution method was used. The calculation of the economic efficiency of the micro-hydropower station was carried out using the method of technical and economic analysis of possible options for electrification by S. G. Obukhov. Results and discussion: based on the results of the verification energy calculations, the effective power on the hydraulic turbine shaft with average technical parameters of low-pressure sprinkler machines was 1.202–15.648 kW. At the same time, linking the operation of the micro-hydropower plant to the irrigation systems of the North Caucasus territory has the potential to get 2596.32–33799.68 kW of generated electricity per year at a cost of 1 kW·h of 0.6204 rubles. Conclusions: the introduction of a micro-hydropower station in the design of sprinkler equipment will provide the ability to generate electricity within the available hydraulic characteristics. With this in mind, for the operation of hydropower equipment, it is necessary to have or create an additional water pressure. The multiple regression equation obtained on the basis of verification calculations of the parameters of the energy block of a microhydroelectric power plant showed that an increase in the water pressure per 1 m Н2О leads to an increase in effective power by an average of 0.611 kW.
