While resonance in towers built on soft soils presents significant design challenges, wind energy has grown to be a major source of demand worldwide for environmentally friendly electricity. This work offers a rapid calculation method for analyzing wind turbine tower frequencies by means of elastic foundation modeling considering soil-structure interaction. Based on frequency synthesis methods, analytical models were developed to explain both translational and rotational stiffness of the foundation. The case model was a 2.0 MW turbine; finite element analysis validation revealed a maximum deviation of just 2.54% over several common soil types. The results show that soft soils lower the natural frequency of the tower, hence causing resonance around the rated speed. Increasing the foundation radius (up to 27%) together with optimal mass distribution will increase the frequency beyond critical safety margins according parametric analysis. The approach facilitates effective early-stage assessment of turbine dynamic behavior under ground conditions relevant for a given site.
