RESEARCHES OF INFLUENCE OF HYDRODYNAMIC PARAMETERS ON OUTPUT CAPABILITY OF SMALL HYDRO-ELECTRIC STATION

The researches of influence of hydrodynamic parameters on the output capacity of small hydro-electric station were pursued in this work. On the basis of experimental results of dependence of rounds on water consumption it is possible to draw the following conclusions. Dependence of rounds on an expense has nonlinear character. At increase in ac-tive loading rounds on the turbine are decreased in proportion to terminate. At an expense of 70 l/s and meaning of load of 300 W geometrical parameters (capacity on the turbine) don't allow to increase power development, turbine camera is overflowed, and water overflows conveying passage. According to the results of small hydro-electric station in no-loaded on the range of rounds from 900 to 1800 r/min no-load voltage on the generator is from 95 to 273 V. With rate speed of turbine 1500 r/min voltage across generator is decreased in proportion to increase in loading, however out voltage of the stabilizer holds stable value in 220 V.
