Opis:: The following paper discusses several aspects connected with the wind farms’ impact on radiocommunication systems. The first part of this article is filled with the analysis of the ITU-R BT.1893 model, which was originally created for the analysis of the interaction between the wind turbines and digital TV receivers in the UHF band. A measurement campaign carried out by the authors confirmed that this model is also applicable for the lower, maritime VHF band. Utilizing the software implementation of this model, the authors conducted a thorough simulation analysis of the wind turbines’ influence on radio systems working in both VHF and UHF bands. The results of these simulations are presented and discussed in the second part of the paper.

Opis:: The article presents an analysis of the use of Savonius wind turbines with vertical axis of rotation. The first part presents an analysis of the literature with the dentification of the properties of the basic atmospheric parameters related to the air movement referred to as wind. Used mathematical descriptions used in the analysis of air movement and enabling the identification of basic thermodynamic parameters of wind turbines with a vertical axis of rotation were presented. Then, the historical background of the development of wind turbines with a vertical axis of rotation was presented, and constructions of this type currently used were described. Proposals for modification of the configuration and design of Savonius rotors and the impact of these activities on their efficiency were analyzed. These issues were presented in relation to the experimental work carried out in the international research centers. Obvious advantages and disadvantages of using this type of equipment in the field of wind energy were indicated.

Opis:: Wind energy is one of the most environmentally friendly energy industries. Wind power is used in more than 70 countries of the world to produce electricity. Wind power plants generate more than 1% of the world’s electricity. Wind energy is considered to be one of the most popular renewable energy sources. In countries where this energy is already widely used, the environmental conditions substantially improve. To increase the efficiency of wind power plants and work reliability, and also to solve other problems, it is necessary to carry out climate research on wind energy and collect information on the distribution of wind energy depending on wind speed profiles, etc.

Opis:: In the author’s opinion, the relaxation of the rules on the construction of wind farms should lead to an increase in investment in this area. However, the author recognises the risk of protests from local communities concerned about the potential health, environmental and landscape effects of the construction of wind farms.

Opis:: Many countries worldwide support green energy production on large scale mostly by solar or wind energy subsidizing manufacture and operation of such systems. During the last two decades, there has been significant increase in wind energy production globally. Statistics show continuously growing investments in the development and installation of wind turbines and farms. Currently, wind energy is the second most important source of renewable energy after water energy. By 2016 global cumulative installed wind capacity surpassed 432 k MW [GWEC]. In last several years, most dynamic growth in wind power generation investments was recorded in Asia. Europe, in comparison, has less impressive but steady growth in wind power plants through the years. In this article, authors present global demand on energy in comparison to efficiency of wind power plants in relation to the local and global location as well as to the scale of installed system. Authors also present statistical data concerning wind power plants development. General classification, using number of criteria (ex. power output, construction size, rotor axis orientation and other) of wind to electric power converting devices is presented. Various types of devices, which authors describe in this article, can perform conversion of wind blow energy to the electric energy using different yet similar methods.

Opis:: Renewable energies have the potential to provide relatively clean energy, mostly for domestic energy. Wind power generation is expected to rise in the near future and has grown exponentially over the past decade in many countries. The most important parameter that must be taken into consideration when designing and studying wind power conversion systems is the wind speed. Probability density functions (PDF) such as Weibull is often used in wind speed and wind power analyses. This research presents an assessment of wind power based on the Weibull distribution statistics in the coastal of southern Iraq at Basrah province. Wind speed data for the study site were obtained from NASA at a height of 50 m for the period 1979–2016 with a time interval of 10 min. The data at a height of 50 m were extrapolated using the power law in order to estimate the wind speed at new heights: 30, 70 and 100 m. The different parameters of the Weibull function as well as the daily and monthly wind speeds, mean, variance and potential energy at four altitudes were estimated and analysed using Windographer software. Results indicate that the maximum wind speed at 100 m is 6.4 m·s–1, giving an average power density of 298 W·m–2, which indicates that the location of the study has marginal and useless potential for installing large wind turbines.

Opis:: The article discusses the historical development and embodiments of the concept of generating electricity from wind energy without the use of wind turbines, so called electrostatic bladeless generators or generators without moving parts. A simplified theory and the principles of operation of generators that use a motion of charged particles in an electric field occurring under the drag force of the wind are described. Two contemporary solutions utilising the principle that has reached an implementation stage, EWICON and AerovoltaicTM, are presented in detail.

Opis:: W opracowaniu dokonano charakterystyki energii wiatru i sposobu jej przetwarzania w energię elektryczną. Zaprezentowano dwa rozwiązania konstrukcji turbin wiatrowych o pionowej osi obrotu i o poziomej osi obrotu uwzględniają ich wady i zalety. Ponadto przeanalizowano warunki klimatyczne w Polsce pod kątem zasobów wiatru i lokalizacji turbin wiatrowych. W opracowaniu wskazano turbiny o pionowej osi obrotu jako rozwiązania pozwalające na szersze i lepsze wykorzystanie zasobów wiatrów w Polsce. Pozyskiwana w ten sposób energia wspomaga istniejące indywidualne instalacje grzewcze bądź oświetleniowe i poprawia lokalne bezpieczeństwo energetyczne.
The purpose of this paper is to characterise the wind energy and to describe its conversion into electric energy. The article presents two design variants for wind energy conversion which are vertical axis wind turbine and horizontal axis wind turbine, pointing out their advantages and disadvantages. Furthermore the climatic conditions in Poland were analysed, regarding wind resources and possible locations of wind turbines. As a result of analyses the vertical axis wind turbine was appointed as the solution which is more suitable for Polish region, allowing for better and wider utilisation of wind energy (in comparison to the other design). The power obtained this way is used as a support for existing individual light and heating systems, and improves local energy security.
