摘要

通过分析各风速下风轮气动转矩特性及发电机在各最大功率跟踪点转矩-转速运行轨迹,依据风电机组在最大功率点上风轮气动转矩与发电机转矩平衡的原理,提出基于发电机电磁转矩的动态最优转速的计算方法,然后以该最优转速为控制目标,设计基于转速偏差的反馈控制器,并做恒转速区与变转速区的控制效果分析。仿真与现场测试表明,该直接转速控制策略可实现最大功率点跟踪,在恒转速区与变转速区具有统一的控制方式,控制逻辑简单实用,有望在风电行业推广,有较好的应用前景。

Abstract

This paper analyzes wind turbine rotor aerodynamic torque at various wind speeds and the generator's torque-speed trajectory during maximum power point tracking. It introduces a dynamic optimal generator speed calculation method based on generator electromagnetic torque. A feedback controller based on speed deviation is then designed and tested for control effectiveness in constant and variable speed zones. Simulation and field tests confirm that this direct speed control approach successfully tracks the maximum power point, offering a unified control solution for both speed zones. The simple and practical control logic holds promise for broad application in the wind power industry.
