Wind power systems participating in primary frequency regulation have become a novel trend. In order to solve the problem of the over-speed deloading (OSD) control of wind power systems failing to provide reserved capacity for primary frequency regulation while under turbulent winds, this paper analyzes the influence mechanism of turbulence characteristics on the OSD control and the relationship between the reserve capacity of OSD control and the deloading power coefficient under turbulent wind speeds, while also quantifying the relationship between the turbulence characteristic index and deloading power coefficient. The range of the deloading power coefficient is obtained accordingly, based on which improved OSD control is proposed to dynamically optimize the deloading power coefficient according to the turbulence characteristics, which improves the frequency regulation performance of wind power systems under turbulent wind speed. According to the simulations and experimental results, the improved method proposed in this paper has good effectiveness and superiority in frequency regulation effect and rotor speed performance.

一种改进的考虑湍流特性的风力发电系统一次调频超速降载控制

风电系统参与一次调频成为新趋势。【摘要】：为解决风力发电系统超速减载(OSD)控制在湍流风作用下无法为一次调频提供后备容量的问题,分析了湍流特性对OSD控制的影响机理及其关系。研究了湍流风速下OSD控制储备容量与减载功率系数之间的关系，同时量化了湍流特性指标与减载功率系数之间的关系。从而得到减载功率系数的取值范围，在此基础上提出改进的OSD控制，根据湍流特性动态优化减载功率系数，提高了风力发电系统在湍流风速下的调频性能。仿真和实验结果表明，本文提出的改进方法在调频效果和转子调速性能方面具有良好的有效性和优越性。
