As a leader in the field of renewable energy, wind power has become an important pillar in the development of new energy due to its immense potential and mature technology. For a long time, hybrid tower wind turbines have supported the conversion of wind energy into electrical energy at heights of several tens of meters in the air with their unique structure. How do hybrid tower wind turbines remain stable at heights of nearly 120 meters, facing the challenges of high power, long blades, and tall towers? They have become the new favorite in the wind power industry. So, let's unveil the mystery of hybrid tower wind turbines!
A hybrid tower wind turbine, as the name suggests, integrates the advantages of steel and concrete in its tower system. Specifically, its lower part uses concrete segments to provide stable foundational support, while the upper part employs steel tower segments to ensure lightness and flexibility. Taking a 6.5 MW hybrid tower wind turbine as an example, its 118.9-meter steel-concrete combined tower consists of a 111-meter "mixed tower" section, a 1.8-meter transition section, and a 6.1-meter steel tower section. These parts are tightly connected by 16 groups of 18 pre-tensioned steel strands each. The mixed tower section is designed as a cone cylinder structure comprised of 37 segments, a total of 136 prefabricated tube segments, and 3 whole-ring prefabricated segments. In simple terms, the tower structure of a hybrid tower wind turbine is like a "chimney" built with building blocks, layer by layer, forming a solid and stable structure.
The advantages of a hybrid tower wind turbine mainly lie in its structural design and performance. First of all, its overall structural rigidity is high, making the unit more stable when operating in high shear wind speed areas and low wind speed high tower scenarios, effectively reducing operational vibrations. Secondly, due to structural optimization, metrics such as the windward angle and power generation of the rotor system are more stable, and maintenance costs are correspondingly lower. Additionally, hybrid tower wind turbines also offer high production efficiency, convenient segmented transportation, and fast assembly and hoisting. These advantages ingeniously solve the transportation and installation difficulties brought by the increase in wind turbine unit capacity and tower base diameter.
The FL RENEWABLES 120-meter to 180-meter UHPC hybrid tower is undoubtedly a revolutionary leap in the field of wind energy technology. This ultra-high hybrid tower not only embodies the solidity and durability of concrete but also showcases the lightness and flexibility of steel, thereby advancing energy capture efficiency to a new level. It not only provides a stable and reliable solution for wind power generation but also achieves unprecedented efficiency in energy utilization. This innovative design of hybrid tower wind turbines significantly enhances energy output, laying a solid foundation for a more sustainable and environmentally friendly future.
With continuous technological progress and profound societal changes, wind power technology has entered a whole new stage of development. As an outstanding representative in this field, the hybrid tower wind turbine, with its unique advantages and innovative design, will continue to occupy a pivotal position in the renewable energy sector. They not only effectively utilize wind resources to convert them into clean, renewable electricity, providing stable support for energy supply, but also play a crucial role in promoting the development and utilization of green energy. Through the widespread application of hybrid tower wind turbines, we can further reduce our dependence on fossil fuels, lower greenhouse gas emissions, and contribute to building a greener, more sustainable energy system.
