The article provides an overview of horizontal-axis wind turbine (HAWT), covering their working principles, components, and control methods. It also explores different blade configurations and materials, along with their advantages and disadvantages. 4 Average annual wind speeds of 6. 5m/s or greater at the height of 0m are generally considered commercially viable. New technologies are expanding the. . While the aerodynamics of wind turbine are relatively com-plicated in detail, the fundamental operational principle of a HAWT is that the action of the blowing wind produces aerodynamic forces on the turbine blades to rotate them, thereby capturing the kinetic energy contained in the wind and. . The layout of horizontal-axis wind turbine (HAWT) arrays in large wind farms poses three main issues: (1) How to select a site. (2) How to arrange the HAWT arrays to achieve greater power extraction at a specific wind farm. HAWT rotors are usually classified according to the rotor orientation (upwind or downwind of the tower), hub design (rigid or teetering), rotor control. .
