The system of complex energy supply of various objects is considered, existing problems in the field of wind power engineering are identified, those that leave complex energy supply using renewable energy sources are analyzed, and the quality of supplied energy is assessed by the efficiency factor. The structural model of wind power plant (HPU) functioning as a subsystem in the autonomous power supply system was considered separately. Methodological bases of designing in the form of structural scheme of methodology of development and creation of rotor HPU have been developed. All stages of designing and development of a wind power plant are analyzed.

The carried-out analysis of designs of granulators for the process of damp pressing showed that this method is implemented by means of screw granulators better. At the same time effective objectives are achieved by production of the end product -granules, their quantitative and qualitative indexes. Preliminary search experiments on pressing of firm fraction of the fermented bird dung in the screwgranulator, which is most meeting the requirements of obtaining a certain quantity of qualitative granules, are made. The unstable movement of the pressed material in matrix dies was as a result revealed. It does not allow to reach the required capacity of the screw granulator and to receive granules with quality characteristics.For realization of an effective objective -obtaining necessary quantity of qualitative granules from firm fraction of the fermented bird dung the constructive and technology scheme of the screw granulator is proved. For this purpose innovations are entered into a design of the screw granulator: zone of plasticization and bladed knife. The zone of plasticization is located between the screw and the matrix in the screw granulator and the bladed knife in the plasticization zone before the matrix.Researches of the process of damp granulation were conducted by means of a multiplefactor planning method of an experiment. During the research of the process of damp granulation of FF FBD in the screw granulator we studied the following factors: frequency of rotation of the screw of the granulator (17-27 rad•s -1 ), humidity of the pressed material (34-40 %) and the number of blades of the knife (0-4 pcs), influencing the productivity and specific expenses of energy. After processing of the results of the experiment performance (in the range of 240-265 kg•h -1 ) specific power costs were received (in the range of 17.1-24, 317 kW•h•t -1 ). The greatest influence both on the performance and specific power costs has the factor of the number of blades of the knife, the smallest -the frequency of rotation of the screw of the granulator. With increase in the number of blades of the knife, also the performance increases.

The article presents a staged scheme for granulation of solid fraction solids of fermented poultry manure (SF FPM) in an augered granulator. Granulation process of material has been reviewed in every stage of compression. The structural and mechanical properties of the pressable material were studied. It was revealed that SF FPM refers to pseudoplastic bodies, which when exposed to pressure exhibit anomalous properties. We present a rheological model of the motion of pressed materials in an augered granulator. We have modeled a mechanical model of actions at SF FPM. It was revealed that the compressible material at voltages generated in an augered granulator at the area of plasticizing was acting like an abnormal liquid. This liquid obeys the regularities of Newtonian liquids
