Abstract

The disadvantage of hydroelectric dams is the flooding and a material breach of the ecology of the region, therefore the use of such hydroelectric power station is reasonable when no alternative method of providing the required power. In this regard, in most cases, it is advisable to use free-flow microelectric power plants. Free-threaded micro hydropower plants constitute a power unit mounted in the flow of the river. The main difference between free-flow microelectric power plants and dams is the use of kinetic energy of the flow, rather than potential. This makes it possible to eliminate the need for earthworks and the construction of additional hydraulic structures. Free-threaded micro hydropower plants can be grouped, forming a cascade of micro hydro. In order to increase the reliability of free-flow microelectric power plants, the design tends to use low-speed generators with rotation speeds from 140 to 650 rpm, which can significantly simplify or completely eliminate the transmission mechanism
