Construction of ecological wave type hydraulic converter when using river flow energy

The article presents material on the strategic direction of reducing the negative impact of the fuel and energy complex on the environment through the transition to renewable energy sources, considered by all countries and forecasted, including in Russia. The European development of renewable energy is shown: in the first half of 2020, more electricity was generated than based on fossil fuels (RES 40%, fossil fuels 34%). The potential of the Russian hydropower industry is shown; in terms of the availability of hydropower resources, Russia ranks second, after the PRC. Historically, the use of a hydropower resource has been viewed as supplying energy from a renewable energy source. With their worthy renewable contribution to the energy sector, exploitation indicates environmental problems associated with their appearance, this is the flooding of large tracts of fertile lands, leading to modifications of unique ecological systems in river beds and floodplains, to a decrease in the number and extinction of fish species. One of the ways of transition to environmentally friendly and resource-saving energy is seen in the development of the hydro potential of small rivers, which has received a stable direction of promising development over the past decades due to the fact that the development does not require large territories, while mini-hydroelectric power plants have a short payback period and a lower cost of the generated 1 kWh of electricity. The prospect of developing microhydroelectric power plants is also seen for their use in the field of decentralized energy supply. The article presents a fundamentally new development of the design of a hydraulic converter for a micro HPP - a wave-type hydraulic converter, which is a device for using the energy of a river flow as a source of renewable energy. The design features of the wave-type hydraulic converter make it possible to simplify the operations for manufacturing the working blade, while the power of the developed device will be determined by the dimensional characteristics of the converting mechanism. The possibility of modular design of wave-type hydraulic converters will determine the total power of the device depending on the number and size of modules.
