Moskalchuk N. Increasing the level of ecological safety when using wind energy in the Carpathian region

The thesis deals with the actual scientific and technical task of increasing the level of environmental safety when implementing wind energy projects for the Carpathian region by improving the individual stages of the environmental impact assessment and geospatial planning of the projected activity area. For the first time, to assess the impact significance from the implementation of renewable energy projects as a part of the environmental impact assessment procedure, it is proposed to use multi criteria analysis by combining a point method in determining the parameters of probability, spatial scale, duration and intensity, and the method of tables and matrices when comparing the impacts, activities and alternatives. The environmental impact of the wind farm “Shevchenkove-1” has been assessed to justify the decision to implement the project. Scientific approaches have been further developed to reduce the effects of wind farms on ornithofauna through the use of vortex ring generators at wind farm sites. The research of the Carpathian region wind energy potential has been further developed through the establishment of modern changes in wind characteristics, the allocation of promising territories and the forecasting of electricity production of specific wind turbines, which allows to increase the level of ecological safety of the region by replacing fossil fuel sources and reducing negative environmental impacts. Methods for the wind farm site selecting have been improved by taking into account scientifically sound geospatial constraints, the use of remote sensing of the Earth and geoinformation systems, which helps to prevent environmental impacts from the implementation of wind energy projects. The algorithm of the site selection was applied using the example of Ivano-Frankivsk region. Functional dependencies were obtained between the sound level of the wind turbine Nordex N43 600 and the distance based on the processing of experimental data and the consideration of sound power.
