The article analyzes the reliability of the operation of small hydroelectric generating units, and proposes automation tools to improve the efficiency and reliability of the equipment. In order to increase the reliability of the operation of a small power plant and uninterrupted power supply of consumers, it is proposed to analyze the operation of the main equipment on the basis of reliability indicators. This analysis will provide an opportunity to solve problems, provide for refusals, monitor the process of production of electricity, improve the durability of aggregates.
The indicated proposals will allow to carry out round-the-clock control over the work of the main units of the small hydroelectric power station, in particular, to detect defects in a timely manner, to prevent failures, to automatically control the water level in the reservoir, that is, to increase the reliability of the operation of a small hydroelectric power station. The proposed solutions will extend the life of small hydroelectric power stations which have been in operation for a considerable time and projects which were developed several decades ago.

Technology, energy, agriculture transport AIC is a scholarly professional journal with a long-standing history and stable academic tradition, reflecting the evolution of engineering and technical sciences within the agro-industrial sector of Ukraine.
The journal was founded in 1997 under the title Bulletin of Vinnytsia State Agricultural Institute. According to the Resolution of the Presidium of the Higher Attestation Commission of Ukraine dated September 11, 1997, the publication obtained the status of a professional scientific journal, which enabled the publication of the main results of doctoral and candidate dissertations in technical sciences. From its inception, the journal positioned itself as an academic platform for addressing current issues of mechanization, electrification, and technical support of agricultural production. During 2001–2014, the journal was published under the title Proceedings of Vinnytsia National Agrarian University. Series: Technical Sciences (State Registration Certificate of Print Media KV No. 16644-5116 PR dated April 30, 2010). Throughout this period, a systematic approach to the selection and peer review of scientific manuscripts was established, the thematic scope of publications was expanded, and continuity of scientific directions as well as the development of sectoral engineering schools was ensured. Since 2015, the journal has been published under its current title, Technology, energy, agriculture transport AIC (State Registration Certificate No. 21906-11806 R dated March 12, 2016). The change of title reflected the expansion of the journal’s thematic coverage and its orientation toward interdisciplinary research in mechanical engineering, energy systems, electrical engineering, transport technologies, automation, and digital solutions for the agro-industrial complex.
