A Chinese green technology company has achieved a significant breakthrough after its two-blade onshore turbine achieved more than 500 days of stable operation.
Envision Energy made the announcement that its smart turbine prototype achieved an availability rate of 99.3% and ran for an average of 2,444 hours without interruption.
It produced electricity at full power for around 3,048 hours per year – equivalent to a three-blade turbine.
The company claims its field performance confirms the two-blade turbine is on par with traditional three-blade machines operating at the same site.
In 2012, Envision’s Global Innovation Centre (GIC) in Denmark successfully developed the “game-changing” 3.6MW offshore two-blade turbine and since it was installed in 2013, it has accumulated significant product development and operational know-how, laying the foundation for its new-generation two-blade turbines.
Its latest onshore turbine development underwent months of rigorous testing and nearly two years of real-world field operation at its smart wind power verification centre.
Lou Yimin, Senior Vice President and Chief Product Officer at Envision Energy said: “By overcoming key technical challenges such as excessive system vibration and load imbalance – barriers that have long held back two-blade designs, Envision has once again redefined wind power innovation by becoming the first in the industry to demonstrate long term operational verification of a next-generation two-blade turbine.”
