Summary
  • Envision Energy has successfully developed a two-blade turbine that matches the performance of traditional three-blade models.

  • After 500 days of continuous operation, the turbine demonstrated reliability and efficiency, marking a significant advancement in wind energy technology.

  • This innovation promises cost-effective solutions for green energy projects, especially in remote areas where transportation of heavy turbines is challenging.

It will now be possible to get the same amount of energy from two-blade turbines instead of three-blade ones. Envision Energy, a Chinese company working in the field of wind energy innovation, has confirmed that its next generation two-blade onshore smart turbine has run continuously and properly for 500 days.

“The turbine operated properly 99.3 per cent of the time, running on average for 2,444 hours without interruption, and producing electricity at full power for approximately 3,048 hours per year,” the company said in a press release, indicating that the two-blade design is capable of delivering performance comparable to conventional three-blade turbines.

This two-blade turbine is based on Envision’s Model X Onshore platform. The Model X is Envision Energy’s onshore wind turbine platform, which is specially designed in such a way that the company builds different models of windmills on this platform. That is, the Model X is a basic framework on which new technologies such as this two-blade turbine have been developed.

The two-blade windmill uses modular design and high-speed double fed induction generator technology. It is built with high performance, lightweight structure and system level efficiency in mind. This system is cost effective, easy to transport and provides a powerful solution for various green energy projects.

“By overcoming technical challenges that have long existed in two-blade designs such as excessive system vibration and load imbalance, we have proven that two-blade turbines can now be commercially reliable. This once again redefines wind energy innovation,” said Lu Yimin of Envision Energy in the press statement.

Envision’s journey in two-blade technology began in 2012 at its Global Innovation Center (GIC) in Denmark, where the company developed a 3.6 MW offshore two-blade turbine named ‘Game Changer’. Since the inception of its prototype in 2013, the company has accumulated extensive product development and operational experience in two-blade designs, which laid the foundation for this new generation of turbines.

To take this technology from theory to commercial application, Envision has rigorously tested this turbine for months under a multi-level, full-process, all-conditions validation system.

The company also conducted field tests for almost two years at its Smart Wind Power Verification Center. With this technological breakthrough, Envision Energy has made it clear that the future of two-blade turbines is not only full of possibilities, but it is a solid step towards reducing the cost of energy production, increasing flexibility and making wind energy accessible to remote areas.

This innovation could prove particularly important in areas where heavy turbines are difficult to transport, or modular solutions are required.
