К ВОПРОСУ ИСПОЛЬЗОВАНИЯ МИКРОГИДРОЭЛЕКТРОСТАНЦИЙ ДЛЯ ЦЕЛЕЙ ОРОШЕНИЯ

Abstract

Purpose: to assess the technological and regulatory and technical capabilities of developing and applying power supply complexes using the energy of water flow, in relation to Russian standards to meet the electricity needs of decentralized reclamation (irrigation) systems. Materials and methods. Scientific and technical materials of Russian and foreign authors, as well as the regulatory and technical base of the Russian Federation were used as the initial data. The information processing methods were comparison, analogy, classification and systematization. Results and discussion. Among various design features of the hydropower equipment under consideration, capable of meeting local needs for electricity and at the same time having the ability to combine with elements of an irrigation network (based on relative dimensions, shape, efficiency, etc.), micro-hydroelectric power plants stand out: with propeller, radial axial, axial and capsule hydraulic turbine. The most effective schemes for installing hydraulic turbines are horizontal direct-flow and vertical Z-shaped ones. Analysis of the register of standards in the field of technical regulation in the sphere of hydropower showed that out of 131 standards under consideration, 106 can be partially applied to micro hydropower plants. Providing low-power hydropower facilities with standardization documentation has a priority in the direction of operation (21 %), monitoring and state control (19 %), and repair and reconstruction (19 %). Conclusions. The functioning of a micro-hydroelectric power station based on the energy of water movement provides for the use of a set of design solutions, which requires additional study in order to be linked to the elements of reclamation (irrigation) systems. The scope of the considered standardization documents can be extended to small hydropower facilities, taking into account the specific features of their operation. In this regard, there is a need for the development of scientifically grounded provisions of existing or being developed regulatory documents.
