| 摘 要： | 针对现有风电机组调频策略中增益系数难以选取的问题，提出一种新颖的风电机组减载调频策略，创新性地取消了辅助频率控制，通过修改功率跟踪特性曲线来提供惯性和一次调频响应。该策略可保证调频过程中任意风速下，机组都可收敛到平衡点，避免因能量过度释放而引起欠速停机问题。该策略在调频控制环节中不含有增益系数，适用于不同风速下的风电机组。最后，通过不同风速下的对比仿真结果验证了所提策略的有效性和优越性。

| Abstract: | In the light of the difficulty to select the gain coefficient in current wind turbine frequency modulation strategy， a new load reduction frequency modulation strategy for wind turbines is proposed， which innovatively eliminates the auxiliary frequency control and provides the inertial and primary frequency modulation responses by modifying the power tracking characteristic curve. The strategy which is suitable for wind turbines with different wind speeds has no gain coefficient in the frequency modulation control. Finally， the effectiveness and superiority of proposed strategy are verified by comparing the simulation results under different wind speeds. |
