METHOD OF SUBSTANTIATION OF PARAMETERS OF HYDRO TURBINES AND THE DERIVATION CHANNEL OF MICROHYDROELECTRIC STATIONS FOR THE CONDITIONS OF THE MOUNTAIN RIVER

Abstract

The article presents the method of researching the parameters of a micro-hydroelectric station for small mountain rivers. It is substantiated that for this region it is expedient to use hydroelectric structures of the derivation type without the use of dams and reservoirs. It was established that for mountain rivers it is advisable to use a Francis radial-axial turbine, the parameters of which must be coordinated with the hydrological characteristics of the river.
It is proposed that the hydroelectric power station works on the general electric grid, since the production of electrical energy can be significant, and the main parameters of the hydroelectric power station can be regulated by the electric grid, in particular the frequency, voltage and current. A methodology for calculating the main indicators of a hydroelectric power plant, in particular its capacity, annual production and cost of electricity, is proposed. The optimization criterion is substantiated - the profit from the produced and sold electricity to the general network at the "green" tariff.
The substantiation of the parameters of micro-hydroelectric station and their number must be carried out on the basis of a selection of all possible options for their placement on the studied river. Since these options can be hundreds, and sometimes even thousands, depending on the length of the river, it is suggested to use statistical simulation modeling to solve this problem. A research algorithm has been developed, which is the basis for statistical simulation modeling of the virtual system "micro-HES - river", as a result of which it is possible to justify the parameters of the hydroelectric power plant for the conditions of the studied river.
