Research on Full-Power Preset Time Control Algorithm of Wind Turbines for Gobi Desert Environments Li Zhang, Lei Wang

Abstract

Wind turbines located in the Gobi Desert and other arid regions are subject to extreme environmental conditions, including frequent sandstorms and significant temperature fluctuations. These factors complicate maintenance and elevate operational costs, necessitating enhanced adaptability and performance in wind turbine controllers. Traditional controllers, which rely on linearized models, often require extensive adjustments and may deliver suboptimal performance. This study introduces a novel collective pitch controller for output power regulation and an independent pitch controller for reducing structural loads. By integrating these controllers into a robust, nonlinear system model, we developed a full-power preset time controller specifically tailored for the challenging conditions of the Gobi Desert. The proposed controller significantly enhances output power stability and reduces turbine loads. Comparative analysis with a gain-scheduled proportional-integral controller demonstrates the superior performance of our proposed solution.
