NO340337B1 - Adjustable Vertical Wind Turbine - Google Patents

Description

1. DESCRIPTION

1.1 Name and use:

Adjustable Vertical Wind Turbine.

The idea behind the invention is to produce stable, environmentally friendly and competitive production of electricity in an offshore aquaculture facility using an adjustable vertical wind turbine with back up.

1.2 Inventor:

Inventor is RS-X AS, Stavanger

1.3. Farming at sea/stream

The starting point for the invention is power for large cages at sea. Farming at sea can mean a large market for wind turbines in Norway and globally. The wind turbine is thought to be placed on a cage. The facility must withstand extreme weather and provide a secure supply of electricity under varying wind conditions.

Later, the invention may have opportunities for use in other markets.

1.4. Summary of the invention

The invention provides a plant according to patent claim 1. The plant is shown in the drawing accompanying the application, and consists of a wind turbine with adjustable rotor blades (4), a generator for the production of electricity (3), a back up section with a diesel generator (2 ) and a battery section (1). The angle of the rotor blades can be turned to adjust efficiency, and the rotor blades can be folded in to avoid damage in strong winds. The recess of the rotor blades is shown in the drawing.

The concept achieves cost-effective production of electricity with good security of supply under varying weather conditions while avoiding damage in bad weather.

The main advantages are:

• The plant can better withstand physical forces in bad weather because the leaves can fold in.

• The rotor blades are adjusted/twisted to adjust efficiency.

• Low center of gravity provides good protection of equipment and easy service/maintenance.

• The wind turbine is connected to reserves in the form of a large battery and a diesel generator.

Especially the combination of twisting and folding in the rotor blades - is known from the past.

1.5. Example of application - farming at sea

• The cage has a large concrete ring - diameter 100 meters or more - with an annular float, on top of the float is a wind and wave breaker that rises well above sea level, on top of the wind and wave breaker is the facility for wind-based power generation.

• The cage has vertical tensile anchoring - which makes it stable and robust in bad weather.

• Automation enables monitoring from land and minimal work at sea.

Secure power supply is important. Power is used, among other things, to power the system for feeding fish. The wind turbine is therefore connected to batteries and a diesel reserve unit to achieve a stable and optimal system for supplying power to the cage over time and under varying wind conditions. A management system receives weather forecasts to be able to optimize in the future.

For farming at sea on this type of facility, wind-based power generation is considered profitable.

Claims (2)

1. The plant for the production of power in farming for sea-characterized wood vertical wind turbine with vertically oriented retractable rotor blades in that the rotor blades are attached above and below with arms to rings in the pole of the wind turbine, and when the rings are pulled towards the center of the pole, the rotor blades are pulled tightly against the pole to avoids damage and breakdowns in difficult weather conditions such as strong winds and high waves, and the connection to the battery and any diesel generator means that the system as a whole provides a secure supply of electricity at competitive costs under varying conditions. 2. Installation according to one of claim 1, in which the production and delivery of power from the unit is controlled and optimized based on the need for power, estimated production of wind power and capacity for battery and diesel generator, so that a safe supply of power is ensured over a longer period, even in periods of little wind.
