In the heart of Serbia, a groundbreaking study is reshaping how we think about wind energy infrastructure. As the world pivots towards renewable energy sources, the “Crni vrh” wind power plant stands as a testament to Serbia’s commitment to green energy. The plant, poised to deliver electricity to consumers in Žagubica, Majdanpek, and Bor, is not just about harnessing wind power; it’s about doing so with unparalleled precision and efficiency.
At the forefront of this endeavor is Dragana L. Savić, a geotechnical engineer from the Rudarski institut in Belgrade. Her research, published in the journal ‘Tehnika’ (which translates to ‘Technique’), delves into the critical importance of understanding the geomechanical structure of the terrain where wind turbines are to be installed. This knowledge is pivotal in determining the type of foundation required—whether shallow or deep—and ensuring the stability and longevity of the turbines.
The “Crni vrh” wind power plant is no small feat. With turbines reaching a staggering 125 meters in height, the wind’s impact is the primary load these structures must withstand. “Due to its stochastic nature, as well as due to the frequent absence of a primary direction of action, the foundation rates are intended to be circular for the largest number of wind turbine positions,” Savić explains. This circular design not only maximizes stability but also simplifies construction and enhances performance.
In two specific locations, the complexity of the terrain necessitated deep foundations on “standing” piles. This decision was driven by a combination of factors, including the wind turbine’s position relative to the slope, the terrain’s stratigraphy, and the geotechnical characteristics of the lithological layers. “In addition, the circular shape is significantly more practical from the point of view of execution, and generally superior from the aspect of behavior (performance),” Savić notes, highlighting the practical and performance benefits of this approach.
The implications of Savić’s research extend far beyond the “Crni vrh” site. As wind energy continues to gain traction globally, understanding the geotechnical aspects of turbine placement will be crucial. This study provides a blueprint for future wind power plant developments, emphasizing the need for thorough geological, geomorphological, engineering geological, and geomechanical testing.
For the energy sector, this means more reliable and efficient wind power plants, reduced maintenance costs, and enhanced energy security. As Savić’s work demonstrates, the future of wind energy lies not just in harnessing the wind but in understanding the ground beneath our feet. This research, published in ‘Technique’, is a significant step forward in that direction, offering valuable insights for engineers, policymakers, and investors alike. As the world turns to renewable energy, studies like these will be instrumental in shaping a sustainable and resilient energy future.
