Characteristics of the vertical wind profile for wind load estimation

LES for wind load estimation by unstructured grid system

ABSTRACT: Recent development of high-performance computers and techniques on computational fluid engineering has enabled us to simulate the complicated flow such as the wind in urban area. Large Eddy Simulation (LES) is expected to be adopted as an effective technique to evaluate wind load on buildings for wind-resistant design. In this research, the accuracy of LES to evaluate surface pressure...

Fatigue load estimation and reduction for wind turbine

Introduction Fatigue is the structural damage that leads the components of a wind turbine to sudden brittle failure when it suffers cyclic loading [15]. As the size of wind turbines is growing, fatigue loads become more and more significant for the design of major structural components. Concerning fatigue in a wind turbine tower, the fore-aft tower foot bending moment is considered as the most ...

Wind Energy Estimation for Production of Electricity in Iran

This paper covers the estimation of the average yearly production of an appropriate wind turbine for different locations in Iran. The effects of topography, the influence of obstacles such as buildings and shelters, the collective effects of the surrounding terrain, roughness classifications, and orographic elements such as hills, cliffs, etc., all have been included in the calculations. A full...

Estimation of Wind Hazard over Canada and Reliability-based Assignment of Design Wind Load

Effect of Wind Speed and Load Correlation on ELCC of Wind Turbine Generator

Utilization of wind turbines as economic and green production units, poses new challenges to the power system planners, mainly due to the stochastic nature of the wind, adding a new source of uncertainty to the power system. Different types of distribution and correlation between this random variable and the system load makes conventional method inappropriate for modeling such a correlation. In...
