【摘要】 针对现代风力发电机组的主力机型变速风力发电机组,建立了机理模型,对额定风速以上的机组变桨距控制,提出了模糊滑模变结构控制方案。该控制方案不仅可以在额定风速以上保持风力发电机组输出功率的稳定,还能有效提高系统运行的柔性。经仿真验证,模型和控制方案是合理有效的,系统具有较强的鲁棒性。更多还原

【Abstract】 Establish a mechanism model for the variable-speed wind turbine which is the main type of modern wind turbine and propose a fuzzy sliding model variable-structure control scheme applied in pitch-controlled. This scheme not only keep the output power of the wind turbine stable but also improve the flexibility of system efficiently. The simulation result show that the model and control scheme are reasonable and the system possess strong robustness.更多还原
