Abstract: In this study, the optimal speed control parameters obtained by field test method make WTG run stably under the gust conditions with uncertain wind conditions and unstable wind speed, and take into account the realization of multiple goals such as energy storage of the wind turbine, stable output and reducing fatigue damage of the wind turbine and its components. It is described the field test method of gust control and optimization of control speed parameters of the WTG in this paper.
