Improvement of the uninterrupted operation of small hydropower plants for power supply of agricultural consumers
Currently, there is an increasing interest in the world in renewable energy sources using the energy of the sun, water of small rivers and wind. One of the most effective areas for the development of alternative energy is the use of energy from small streams with the help of small, mini and micro hydroelectric power plants (SHPPs). The uninterrupted power supply of consumers and the classification of failures of the power supply system of agricultural consumers are considered. To assess the operational characteristics of SHPPs and electrical equipment in the power supply system, it is proposed to use the uninterrupted power supply coefficient of non-repaired electrical equipment Kbne, the availability coefficient of uninterrupted power supply Kgbe and the uninterrupted power supply coefficient of consumers Kbep. Recommendations on the values of Kbne, Kgbe and Kbep in different operating modes of consumers, powered by both traditional and alternative sources of electricity (in particular, from SHPPs) are considered and ways to increase them are suggested. The implementation of the recommendations will increase the uninterrupted power supply of consumers and obtain an economic effect by reducing damage from interruptions in power supply, as well as reduce the additional costs of manufacturing SHPPs.
