Abstract
A wind guide system to speed up wind at a wind turbine and thereby improve its energy production is disclosed. The wind guide system is built with modules like load-bearing piles, steel sheet piles, shipping containers or straw bales. The main purposes of the invention are to save overall costs for new wind guide system installations to improve the cost of renewable energy, to reduce the CO2 footprint of the wind guide system and to adapt it better to site conditions and the environment. The main cost savings comprise manufacturing costs, transportation costs from the factory to the often-remote wind turbine sites and installation cost and time.
Claims14
A wind turbine system comprising a wind guide system (6) and a wind turbine (1);
- the wind guide system (6) comprising modules (7, 8, 9, 10, 11, 14) for guiding the wind in front of the wind turbine (1) from a first direction to a second direction;
- the wind turbine (1) comprising a tower (3) and a rotor provided with a number of rotor blades (2) defining a rotor swept area (4);
- the wind guide system (6) comprising a ground-based, seabed-based, or floating wind guide with a horizontal length of at least 60 meters, a vertical height of at least 5 meters, a horizontal width and with at least two ends, arranged and configured to receive wind (5) from an altitude below the rotor swept area (4) and to direct the wind (5), so that the second direction of the wind (5) leaving the wind guide system (6) is different than the first direction of the wind (5) received by the wind guide system (6);
- the wind guide system (6) is arranged and configured to direct the wind (5) to an area in front of and/or behind the rotor swept area (4), characterised in that said ground-based, seabed-based, or floating wind guide system (6) comprises at least 10 wind guide system modules (7, 8, 9, 10, 11, 14).
A method for transporting, erecting and assembling a wind guide system (6) being a part of a wind turbine system comprising the wind guide system (6) and a wind turbine (1);
- the wind guide system (6) comprising modules (7, 8, 9, 10, 11, 14) for guiding the wind (5) in front of the wind turbine (1) from a first direction to a second direction;
- the wind turbine (1) comprising a tower (3) and a rotor provided with a number of rotor blades (2) defining a rotor swept area (4). the wind guide system (6) comprising a ground-based, seabed-based, or floating wind guide (6) with a horizontal length of at least 60 meters, a vertical height of at least 5 meters, a horizontal width, and with at least two ends, arranged and configured to receive wind (5) from an altitude below the rotor swept area (4) and to direct said wind (5) so that the second direction of the wind (5) leaving the wind guide system (6) is different than the first direction of the wind (5) received by the wind guide system (6), where the wind guide system (6) is substantially arranged perpendicular to the ground (13) or seabed (13) and it is arranged and configured to direct the wind (5) to an area in front of and/or behind the rotor swept area (4), characterised in that the ground-based, seabed-based, or floating wind guide system (6) is transported onsite in trucks and erected on site from at least 10 modules (7, 8, 9, 10, 11, 14) with mobile cranes and anchored to the ground by means of a piling process or a foundation construction.
