| 摘要: |
| 风电机组参与一次调频缓解了传统同步机组的调频压力，但其调频性能受功率跟踪方法的影响，不利于系统频率稳定。为此提出了基于改进转子转速和桨距角协调控制的一次调频策略，在全风速范围内预留调频所需功率裕度，在系统频率波动时能够提供快速且持久的有功支撑，实现对风电机组静调差系数的整定。对比分析不同减载控制策略下机组疲劳载荷和损伤等效载荷，结果表明所提策略可有效降低机组的疲劳载荷，延长使用寿命。最后，通过仿真验证了所提一次调频策略的有效性，频率改善效果优于传统一次调频控制，提高了风电场参与系统频率调节服务的一致性和可预测性。 |

| Abstract: |
| The participation of wind turbines in primary frequency regulation relieves the frequency regulation pressure of traditional synchronous generators, but its frequency regulation performance is affected by the power tracking method, it is not conducive to system frequency stability. Therefore, a primary frequency regulation strategy based on improved coordinated control of rotor speed and pitch angle is proposed to reserve the power margin required for frequency regulation in the full wind speed range, which can provide fast and durable active power support when the system frequency fluctuates and realize the rectification of the static regulation differential coefficient of wind turbines. By comparing and analyzing the fatigue load and damaged equivalent load of the wind turbine under different de-loading control strategies, the results show that the proposed strategy can effectively reduce the fatigue load of the wind turbine and extend its service life. Finally, the effectiveness of the proposed primary frequency regulation strategy is verified by simulation, and the frequency improvement effect is better than the traditional primary frequency regulation control, and it improves the consistency and predictability of the wind farm participation in the system frequency regulation service. |
