“…Так как этот миграционный коридор лежит вне зоны активных исследований зарубежных орнитологов, то он остаётся «белым пятном» (Prins, Namgail, 2017). Отсюда до последнего времени не было никаких сведений о параметрах миграции, полученных новейшими средствами (например, GPS/ GSM-прослеживанием), до сих пор не ведётся исследований с помощью радаров и даже отсутствуют какие-либо системные визуальные наблюдения за миграцией на современном уровне, подобные тем, которые ведутся в Грузии (Vansteelant et al, 2014;Wehrmann et al, 2019) или в Непале (Gurung et al, 2004;2019;deCandido et al, 2013;Subedi et al, 2017).…”

On the basis of data obtained from ARGOS/GPS and GPS/GSM tracking of 34 eagles (4 Steppe Eagles (Aquila nipalensis) from Central KZ, 1 Steppe Eagle from Southern Ural region, 22 Steppe Eagles, 5 Eastern Imperial Eagles (Aquila heliaca) from the ASR and 2 Greater Spotted Eagles (Aquila clanga) from the from the Altai-Sayan Ecoregion), we have defined the main flyways, terms, and other parameters of migration of eagles through Eastern Kazakhstan. We have outlined the borders of the migration corridor and estimate the number of migrants passing through it. The study highlights the importance of the Karatau ridge for eagles from the vast territories of Russia and Kazakhstan. But we are also concerned about the development of wind farms with horizontal-axis wind turbines that expose ultimate danger for raptors in the Karatau migration corridor. One of them already exists – the Zhanatas Wind-Power Station. Here we calculated the possible negative impact on the eagle population from the existing and projected wind farms of the Karatau ridge and give our recommendations for neutralizing the damage from the development of the electric power industry in Karatau.

Vertical axis wind turbines received renewed attention for increasing offshore wind energy harvesting and in urban environments. This turbine reflects a specific type of technology that generates electricity from wind, which is renewable sources of energy. This research explores the effect of blade profile modifications on the VAWT aerofoil NACA0012 and NACA2415. Analysis of the lift/drag coefficient and calculation of the average torque/self-starting potential of NACA0012 and NACA2415 for NACA0012, as this is a significantly better measure of the power generated at different pitch angles and comparison of both profiles. The dataset is created using Computational Fluid Dynamics (CFD) simulations, which were performed in ANSYS-Fluent. Various parameters, such as the number, thickness, and angle of attack of the Reynolds no. were investigated. The aerodynamics of the wind turbine blade is shown to increase the optimized form of the modified aerofoil.

Comparison of Small-Scale Wind Energy Conversion Systems: Economic Indexes

Wind energy is considered as one of the most prominent sources of energy for sustainable development. This technology is of interest owing to its capability to produce clean, eco-friendly, and cost-effective energy for small-scale users and rural areas where grid power availability is insufficient. Wind power generation has developed rapidly in the past decade and is expected to play a vital role in the economic development of countries. Therefore, studying dominant economic factors is crucial to properly approach public and private financing for this emerging technology, as industrial growth and energy demands may outpace further economic studies earlier than expected. In this study, a strategy-focused method for performing economic analysis on wind energy based on financial net present value, levelized cost of energy, internal rate of return, and investment recovery period is presented. Numerical and simulation results depict the most optimal and economical system from a 3 and a 10 kW wind energy conversion system (WECS). Moreover, the aforementioned criteria are used to determine which WECS range is the most suitable investment with the shortest payback period. Finally, an economically viable and profitable wind energy system is recommended.
