Experimental Investigation of Energy Losses due to Icing of a Wind Turbine
Ice accretion and irregular shedding cause many potential problems during turbine operation. For example, icing causes large load imbalances; creates excessive turbine vibration; can change the natural frequency of blades; promotes higher fatigue loads, and increases the bending moment of blades. Icing issues can directly impact personnel safety, due to falling ice. It is therefore important to conduct research on wind turbines operating in cold climate areas. This article presents an experimental investigation wind energy losses, when a wind turbine prototype is operating under icing conditions. A turbine model with curved 3-D blades and a DC generator was tested in a large refrigerated wind tunnel, where ice formation is simulated by sprayed water droplets. The current, voltage and rotation of the DC generator are measured through a Data Acquisition system and recorded with Labview software. This paper will present the power losses under various icing conditions.
