W artykule przedstawiono problemy oraz wyzwania stojące na drodze do wielopłaszczyznowego rozwoju energetyki wiatrowej. Omówiono występujące globalnie zasoby wiatru oraz możliwości energetyczne poszczególnych rejonów Polski. Przedstawiono dotychczasowy rozwój siłowni wiatrowych, a także potencjalne ścieżki ich dalszej rozbudowy. Omówiono przykłady dużych instalacji wiatrowych oraz problemy, z jakimi zmagają się ich operatorzy.

Wind energy is one of the most abundant energy sources on Earth. In recent decades the most of technological problems of wind farms were resolved, unfortunately the main problem lies instability and predictability of wind conditions remain. Obstacles in the construction of wind farms are also impact on the environment and requirements for the accompanying infrastructure.

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.

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.

Świnoujście is a Polish seaport located on the Pomeranian Bay, on the southern coast of the Baltic Sea island of Usedom and Wolin. The port is situated in the Świna Strait in Świnoujście, Western Pomerania. The harbor consists of a cargo handling quay, passenger terminal and marina. The seaports of Świnoujście and Szczecin are closely linked economically to form a team and are connected by a passage through the Szczecin Lagoon. All big ships directed to Szczecin have to be routed through the port of Świnoujcie. The hydro-meteorological conditions in the Świnoujście Port area and surroundings, affecting safe maneuvering of ships, are analyzed by statistical methods. The conditions studied, with the aid of Port Captain logbook, are: currents, winds, water level, ice conditions and visibility. The statistical distribution of water level was analyzed and proposed as decision-making tool during a ship’s approach to Świnoujście Port.

During five campaigns at sea and 11 on land in 2001-2007, aerosols were measured in the coastal zone and over the open sea in the Gdańsk Basin (southern Baltic). Sea salt concentrations were high both over Gdynia (2.0-12.2 žg m-3) and at sea (1.3-14.5 žg m-3). The intensity of the generation and transport of marine aerosols increased exponentially with wind speeds > 5 m s-1 over land and > 3 m s-1 over the Gulf of Gdańsk, this being most noticeable with Baltic and oceanic advection. Sea breezes were conducive to the transport of marine aerosols over land areas. The sea was also the origin of both sea salt and non-sea salt sulphate aerosols. An interesting increase in the proportion of non-sea salt-related sulphates (86.7%) was observed in spring, when the biological processes in the sea were more intense.

In this paper a statistical analysis of wind conditions occurring in the Odra estuary has been presented. The measurements of wind directions and velocities from years 1970-1995 for four meteorological stations of IMGW: Świnoujście, Dziwnów, Trzebież and Szczecin-Dąbie have been analysed.
