Aerogenerador de eje vertical para vientos de velocidad variable


Oferta Tecnológica
Una pyme húngara ha desarrollado un aerogenerador de eje vertical con sistema propulsor y regulador para compensar la producción de energía en zonas con vientos de velocidad variable. El objetivo de la empresa es suministrar energía en comunidades pequeñas en áreas en las que la velocidad media del viento hace económicamente inviable el uso de aerogeneradores más grandes. El aerogenerador se instala en estructuras elevadas, tejados de edificios altos, pendientes y parques eólicos existentes. La empresa busca socios para licenciar la patente o know-how.


Vertical axis wind turbine for slow and changing wind speed
A Hungarian SME has developed a small vertical axis wind turbine with booster and regulator system to balance out the energy production at changing wind speeds. The company is interested in licensing the patent and/or know-how.
A Hungarian company active in the fields of construction, trade and services has developed a solution to accelerate and regulate the wind speed to handle low wind speed and high wind gusts. The presented product is in the capacity range where other vertical axis wind turbines (VAWTs) are however its energy production is more effective. The Hungarian firm is looking for industrial partners interested in licence agreement.

The novelty is the special regulation system that accumulates small and releases the extreme high winds, hence no need to stop the turbine in strong winds.
- Regulator: In order to protect the system in extreme winds, the system will open its valves over a certain level of wind speed and the inlet wind utilizes gusty winds.
- Booster: The all-round booster enables the wind turbine to accelerate 7-10 times the inlet wind speed from any direction.
This provides balanced energy production, and - in case of multiple installed equipment - effective and scheduled supply to the grid.

The company is not competing rather completing the still existing wind generation technologies. It is providing energy for smaller communities in the areas where the average wind speed makes uneconomic the large turbines .

Potential applications:
The wind turbine can be installed on:
- elevated structure (the high wood or steel platform provides underneath storage area and easy access for maintenance)
- the top of high buildings and to hill slopes
- existing wind farms where the wind conditions are known and the needed infrastructure is available and can be further utilized

With this variety of placement the wind turbine is perfect for:
- complementary energy production tool for existing horizontal axis wind farms
- producing energy for flood protection, irrigation, military bases, etc.
- rural areas to produce the energy that is unavailable or unreliable
- community focused energy source e.g. for electric "filling stations"
Advantages and Innovations:
The objective of the development was to find a solution to make the winds work in the speed ranges where other solutions are unable to work efficiently. There is no efficient solution for utilizing small winds and also the changing direction can be a difficulty. Simultaneously - even in the low average wind speed areas - there are high wind gusts that are hazards for most of the existing turbines. The changing direction and changing speed - especially the short time wind gusts - can result regulation problems and/or the stopping of the large turbines or even for the small horizontal axis turbines that are faced to the prevailing winds.

Customer benefits:
- long life span
- easy to install
- low maintenance cost
- simple, modular construction
- depending on the volume of consumed annual; the estimated production can meet the demand of 4-10 families
Stage of Development:
Prototype available for demonstration
Patent(s) applied for but not yet granted
CommeR Statunts Regarding IPR Status:
PCT application registered

Partner sought

Type and Role of Partner Sought:
The company is looking for industrial partners ideally with strong marketing, logistics and design capabilities. Some wind generation experience is advantage.
The technology is offered for licensing for any country around the world. In the countries where the intellectual property (IP) protection is not perfect the only form of transfer is the one off IP sales. The default for selling is the IP sales for the global rights of manufacturing and trading.
