Abstract:
This paper presents one possible solution of combined electrical power supply for
smaller military unit in desert conditions. Proposed mobile power generation set, of
1 kW rated power, has: photo-voltaic (PV) solar panels (with ability to be oriented in
the position suitable for electricity production), wind-generator, storage battery and
small petrol aggregate. Such solution allows long-term supply of necessary
communication and other equipment, and supply of possible device for water desalting.
The paper presents technical characteristics of created model, which consists of 760 W
PV-supply, wind-generator of 250 W rated power, storage batteries of capacity 250 Ah
at 24 V voltage level, and petrol aggregate of 1000 W rated power. Besides that, some
results of the system's testing, done in average, continental climate conditions, are also
presented in the paper. Tests were conducted during several months and shown also
very high reliability level of system's components itself. The paper also emphasizes the
possibility of creating such systems with extended rated power range, over 1 kW.
Concerning the fact that the purpose and utility value of this independent electrical
power supply system overcome the importance of its investment costs, it can be very
prominent for military applications.
