摘要

研究风力发电变桨控制系统,针对变桨参数影响安全问题,为了提高风机变桨系统抗扰能力使其稳定运行,提出而建立变桨系统的计算机模型并搭建变桨系统地面仿真平台.对变桨系统进行数学建模和分析变桨系统的扰动力矩,结合实际电动变桨系统的控制结构完成变桨系统的计算机建模并搭建变桨系统仿真平台.结果表明,变桨系统仿真分析设计控制参数,系统抗扰能力强、稳定性好.仿真结果证明可为实际应用提供参考.%In order to improve the anti-disturbance ability of pitch system and to stable operation, put forward the computation model of pitch system, build the simulation platform of pitch system and simulated it. Put the mathematic model, analyze the disturbance torque of pitch system, complete the computation model with the actual control structure, and build the simulation platform of pitch system. Results show that designing control parameters of pitch system based on simulation is of high immunity of disturbance and stability. The simulation results have reference value for practical application.
