Headquarters in Neunkirchen (Saar)

The Vensys Energy AG (proper spelling VENSYS ) is part of the wind energy industry . The main business field is the development and construction of gearless wind turbines . Vensys acts as a licensor for several non-European manufacturers of wind turbines, and Vensys also manufactures small-scale systems at its headquarters in Neunkirchen (Saar) . The Vensys Group includes a. the company Vensys Elektrotechnik GmbH in Diepholz , which manufactures the electrical components, and the company NEVEN Windenergie GmbH in Trier , which is active in project development. The Goldwind Wind Energy GmbH , headquartered in Hamburg, is the largest since 2008 with a 70% share individual shareholder of the company.

history

The Vensys company originally emerged from the Wind Energy Research Group (FGW) founded in 1990 under the direction of Friedrich Klinger at the Saarland University of Applied Sciences . After successful research work, the first “Genesys” prototype with 600 kW went into operation in 1997 . Vensys Energiesysteme GmbH & Co. KG was founded by members of the research group in 2000 as a spin-off from the University of Technology and Economics. The resulting engineering office concentrated on the further development of gearless technology. In 2003 the first prototype of the Vensys 62 with 1.2 MW was built. The license partnership with the Chinese wind turbine manufacturer Goldwind began in the same year . This made Goldwind the first company that was authorized to manufacture and sell Vensys wind turbines under license. In the following year, the 1.5 MW turbine with an enlarged rotor diameter was developed. In 2007, Vensys Energiesysteme GmbH & Co. KG changed its name to the non-listed Vensys Energy AG. In the same year licenses were granted to ReGen Powertech ( India ) and IMPSA Wind ( Brazil ). Goldwind GmbH joined the company as a new co-partner in 2008, which enabled further company growth and the establishment of an own production facility in Neunkirchen (Saar) . In 2010 the first Vensys 100 with an output of 2.5 MW was put into operation. AOI ( Egypt ) was the last licensee to join in 2012 .

technology

Compared to most other wind turbine manufacturers, Vensys wind turbines have some special technical features that apply to all Vensys system types. The gearless system concept, which was followed from the beginning, is characteristic. The speed of the rotor corresponds to the speed of the generator , so that a potentially failure- prone and maintenance-intensive gear can be dispensed with. Instead, a permanent magnet synchronous generator is used, which means that, compared to separately excited generators, no excitation power is required and, at the same time, the tower head mass is saved. The generator is designed as an external rotor, which has the advantage that no excitation power has to be transmitted with a slip ring . The cooling system is implemented by air cooling, which is considered simple and robust. The blade adjustment system with toothed belt drive is another special feature of Vensys wind turbines. This form of the pitch system is lubrication-free and requires little maintenance. Vensys uses a full converter system , whereby the manufacturer promises advantages in meeting the technical requirements for the network properties. Five percent of wind turbines worldwide are based on Vensys technology (as of September 2016).

Plant types

Vensys wind turbine in Tholey

1.5 MW platform

According to the company, the 1.5 MW system is the most frequently built gearless wind energy system in its class. 11,685 units have been built since 2003 (as of March 2017). The 1.5 MW turbine is offered with a rotor diameter of 70, 77, 82 and 87 meters and a hub height of 61.5 to 100 meters, depending on the type of turbine.

In 2012, the Hannover-Marienwerder wind turbine was built with a rotor diameter of 77 m on a 100 m high wooden tower . This is the first wind power plant to use wood as a building material for the tower .

2.5 MW platform

The first 2.5 MW turbine was installed in 2010 and 2,095 turbines of this type had been commissioned by March 2017. The rotor diameter is offered in 100, 109 and 112 meters and the hub height can vary between 93.5 and 140 meters depending on the type. A main difference to the 1.5 MW platform is the active cooling of the generator through a closed air cooling system. The 1.5 MW platform is cooled passively by the outside air.

3 MW platform

The 3 MW platform has been offered since 2015. Technically, this is based on the 2.5 MW system. The 3 MW turbine is offered with a rotor diameter of 112 and 120 meters and a hub height of 90 to 140 meters, depending on the type of turbine. The typical gearless design, the air-cooled and encapsulated generator and the use of permanent magnets are named as product advantages, with a good suitability for low wind locations. In 2018, the 4.1-megawatt Vensys 115 model, the most powerful turbine to date, was presented.

Licenses

Since 2003, Vensys wind turbines have also been built under license by partner companies . The licensees include Goldwind from China, ReGen Powertech from India and AOI - Arab Organization for Industrialization from Egypt. Vensys and its licensees operate in China, India, Germany, Poland, Great Britain, Portugal, Canada, USA, Brazil, Ecuador, Egypt, Cyprus, Sri Lanka and Australia. Goldwind is the largest licensee of Vensys and at the same time the second largest wind turbine manufacturer in the world based on the newly installed system capacity (as of 2013).

Installed capacity

Worldwide, wind turbines based on the concept developed by Vensys have an output of 26,878 MW (as of March 2017). Vensys has installed 346.9 MW of this itself - mainly in Europe. Goldwind has 24,181 MW, followed by ReGen Powertech with 1,887 MW.
