Abstract:

Multi-Rotor Horizontal Axis Wind Turbine (MR-HAWT) system with three 2kW Horizontal Axis Wind Turbines (HAWTs) is the research object. After some appropriate simplifications, the finite element model is established and verified by experiments. The vibration characteristic of the tower under rotors’ periodic excitations is studied through transient analysis method and compared with 6kW single-rotor HAWT system. The result shows that the maximum stress of the 3-Rotor Horizontal Axis Wind Turbine (3R-HAWT) system is less than the single-rotor HAWT, so the safety of the 3R-HAWT system is superior to the single-rotor HAWT system.
