Annotation

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.

Keywords: small HPP, unit reliability, reliability increase algorithm, automation means, automatic control system
