Opis:: The following paper covers a method for wind turbine selection with a horizontal axis of rotation basing on real in-field measurements of wind conditions. The basic meteorological properties and characteristics obtained during measurement campaigns using necessary equipment as well as the used methodology are vital for successful investment in wind farm. The main goal of in-field investigation is to collect meteorological data using a measurement mast installed at the possible future wind farm location. The conducted measurement campaign provided wind directions, velocities and wind blast parameters. The measurements were conducted in the northern Poland using measuring system installed on 100 meter high mast. The system was equipped with all devices necessary to measure and record the basic wind parameters. The reliability of measurements was verified using statistical data for the Weitbull distribution and the wind rose. In this way, the energy potential of raw air stream that could possibly drive a wind turbine was determined. Among 6 pre-selected wind turbine types, the optimal one for a given location was proposed.

Opis:: The following paper presents a methodology of wind turbines selection with a axis of rotation based on measurements of wind conditions specific for the wind power sector. Basic properties and characteristics used in the wind power sector, as well as a proper measurement campaign along with determining the necessary instrumentation and the methodology of its use, are the basic parameters that determine the decision of wind farm investment. The main goal of those activities is to gather the accurate meteorological data in sufficient amount using a measurement tower situated at a possible future location of a wind farm. This method is used to identify the direction, speed, gust and energy of the wind. Measurements were made in northern Poland using a measurement system based on a 80-meter-high telescopic mast. The system was equipped with instrumentation necessary to measure and record the basic wind parameters, and was made by the Windhunter Serwis Ltd. Company headquartered in Koszalin. The reliability of measurements was verified using the statistical methods based on the Weitbull’s distribution and the windrose. Thus, the energy potential of the raw air stream was determined with a possible future use in a wind farm sitting.

Opis:: In this paper, an atypical resistance rotor of a vertical axis small wind energy turbine is to be aerodynamically investigated and later on optimized in a flow simulation. In this report the results obtained from the flow simulations of the single and two rotor setup, as well as the results from the flow simulations of a single blade, are presented. The geometry of the rotor and blades is the base geometry for further optimization. All simulations are performed with one specific tip speed ratio. The base geometry for slat and baffle can be calculated based on experience gained in previous studies. It was found in previous experiments that a rotor with 42% coverage (area that occupies the wings of the total circumference) is always started. Those experiments have also shown that a rotor with 36.5% coverage has a higher power coefficient at low wind speeds, at higher wind speeds, the rotor with 42% coverage has a better power coefficient. Based on those first investigations the optimization of the blade and rotor geometry will be carried out later in this project. Another focal point will be the investigation of the "stacking" of two wind turbines on top of each other in order to obtain a stable torque over the entire circulation and the determination of the optimal distance between two rotors.
