Machinery life cycle efficiency models for their sustainable development

The work describes the components of efficiency in the form of energy, economic and ecological benefits and outlays in the life cycle, i.e. construction and operation of machinery, equipment and power systems, on the example of wind farms and the most important models useful in designing their construction and operation for increasing system safety in three areas: environment, technical system, and human health. Technical conditions (ideas, constructions and processes) necessary to increase the benefits and / or reduce energy, economic and ecological expenditure of the operation and the prospects for effective development of the global, European and national wind energy market are characterized. A preliminary analysis of the relations of operators, workpieces, live and artificial objects of the 2-MW wind farm environment was carried out, for the possibility of increasing the benefits and reduction of outlays as a result of compensating for the destructiveness of the system, the environment and man.
