A study on power output of horizontal-axis wind turbines under rain

Abstract

The generated power of the wind turbine are significantly affected by the air conditions of the operating environment. Rain is a widespread phenomenon in many parts of the world especially in Vietnam, so studying the generated power of wind towers during rain will make a contribution to designing new wind turbines. In this paper, an analytical a method and a model are developed to estimate the effect of precipitation by simulating the actual physical processes of the rain drops forming on the surface of the blades of horizontal-axis wind turbines (HAWT), thereby determining optimal wetness, then power and performance respectively. Consequently, it gives a contribution to operation and control strategies for horizontal-axis wind turbines.
