Abstract The concept of hybrid controlling logic (HCL) combining four models (maximum power point tracking (MPPT), maximum-torque loading current, three phase short circuit, and mechanical brake) is proposed in this paper. The HCL gathers the blade's aerodynamic and generator characteristics, and can be designed according to different purposes, such as high efficiency, low noise, and extreme safety. The MPPT is determined by matching the turbine blades and generator in the constant-voltage (CV) mode. As the optimal constant voltage of output is selected, the characteristics of the operating points can be identified. In the model of maximum-torque loading current, the output current of the generator will be raised to meet the maximum torque for braking. The HCL is simulated on a domain-specific language (DSL) framework with random wind speeds. A horizontal wind turbine is treated as a studied case herein. Two HCLs are designed for different purposes: low noise and high efficiency, respectively, and simulated by the DSL framework. It is shown that the proposed HCLs can successfully meet the desired purposes and efficiently restrain the rotating speed within the safe range.

为风力涡轮机系统提出混合控制逻辑 (HCL)，并通过 DSL 框架进行验证

摘要 本文提出了结合四种模型（最大功率点跟踪（MPPT）、最大转矩负载电流、三相短路和机械制动）的混合控制逻辑（HCL）的概念。HCL 集合了叶片的空气动力特性和发电机特性，可根据不同用途进行设计，例如高效、低噪音和极致安全。MPPT 通过在恒压 (CV) 模式下匹配涡轮叶片和发电机来确定。由于选择了最佳的输出恒压，可以识别工作点的特性。在最大转矩负载电流模式下，将提高发电机的输出电流以满足最大制动转矩。HCL 在具有随机风速的领域特定语言 (DSL) 框架上进行模拟。水平风力涡轮机在本文中被视为一个研究案例。两种 HCL 分别针对不同的目的而设计：低噪声和高效率，并由 DSL 框架进行模拟。结果表明，所提出的 HCL 可以成功地达到预期目的，并有效地将转速限制在安全范围内。
