Loads Analysis and Weight Optimization of 5 MW Wind Turbine Lattice Tower

Wind turbines Transform mechanical energy of the wind into electrical energy. It& #039, s placed on the top of a mast or tower where they are more affected by the wind. The tower construction doesn& #039, t just carry the weight of the nacelle and the rotor blades, but must also absorb the huge static loads caused by the varying power of the wind. Lattice tower is the alternative support structure for wind turbine tower. This paper investigates the stiffer and lighter lattice tower that could be achieved in the design of lattice tower shape and cross-section of the building Material. Model of Six Lattice towers which are modeled in two different shapes and three different cross sections are designed and analyzed under static and dynamic load using ANSYS Mechanical APDL 15.0 software. Combination of tower shape and cross - section which gives optimum stiffer and lighter tower is identified by comparing the results of the analysis using the quantitative and graphic method.
