The turbine deflection angle was gradually changed from 100 to 400, and theoretical and
experimental studies were carried out (Fig. 4).
Fig. 4
. Graph of power versus turbine deflection angle
As
can be seen from the graph, at a turbine deflection angle of 25
0
,
the maximum
theoretical power is 1000 W, and the maximum power obtained from the experimental study
is 684.4 W.
A graph of the dependence of power on water consumption is shown in Figure 5, and it
has been established that as the power values obtained in theoretical and experimental studies
increase, the values of water consumption also increase.

Based on the block diagram of a combined power plant, a combined power plant was
developed, consisting of a 4 kV solar photovoltaic plant and a 0.7 kV micro-hydroelectric
power plant. Combined energy device: Archimedes screw turbine, 8 solar panels of 500 W
each, hybrid controller, 2 batteries with a capacity of 60 Ah, ballast load 5 Ohm and power
3000 W, inverter CH-4000W [22]. A Chinese-made hybrid device under the MARS ROCK
brand was used as a controller.
