| 摘要: |
| 针对传统风电场一次调频算法的风电机组调频效果差、轴系振荡的问题，提出了一种考虑机组旋转备用分类的风电一次调频协同控制算法。首先，根据机组的功率调节能力、释放旋转储能能力和安全转速运行要求，将风电场内机组划分为4类，分别为优先旋转备用、一般旋转备用、弱旋转备用和无旋转备用机组。其次，获取不同限功率条件下的优先旋转备用机组的一次调频能力。然后，对于优先旋转备用机组，采用按调频能力分配的风电场一次调频系统控制算法。最后，在仿真平台上对所提算法进行验证。实验结果表明，所提算法能满足电网调频需求，调频效果优于传统的风电场一次调频算法，且风电机组的轴系振荡明显降低。 |

| Abstract: |
| To address the issues of poor frequency regulation performance and torsional oscillations in traditional wind farm primary frequency regulation algorithms, this paper proposes a coordinated control algorithm for wind power primary frequency regulation considering dynamic classification of unit spinning reserves. First, according to the safe speed operation requirements, power regulation capability, and releasable rotating energy storage capacity, the wind turbines in the wind farm are divided into four categories, namely, priority spinning reserve units, general spinning reserve units, weak spinning reserve units, and non-spinning reserve units. Second, the primary frequency regulation capability of the priority spinning reserve units under different power limit conditions is obtained. For these priority units, a wind farm primary frequency regulation control algorithm based on frequency regulation capability is adopted. Finally, the proposed algorithm is verified on a simulation platform. The experimental results show that the proposed algorithm can meet the primary frequency regulation requirements of the power grid, achieving better frequency regulation performance than traditional algorithms, and significantly reduce shaft oscillations in the wind turbine units. |
