Development of Mini Hydroelectric Power Station in Tobol River in Republic of Kazakhstan for Supply of Low-Power Consumers

The purpose of our paper is to justify the choice of using the working body of the mini-hydroelectric power plant for supplying electricity to the power supply system of low power consumers on the Tobol River in the city of Kostanay. The potential of hydro power resources of the Tobol River near the installation site of mini HPP is analyzed in this paper. The results on the optimization of parameters of hydraulic turbine blades for obtaining the greatest efficiency are given. The correction of the parameters of the blade twist angle along its length performed by this method confirmed that the most effective is a 3-blade hydraulic turbine with a correction angle of a = 5° at a watercourse speed of 1.0; 1.5 and 2 m/s.
