| 摘要: |
| 本着在阵风工况下，变桨控制器提前动作与快速动作的原则，结合变速变桨控制算法基本结构，在基本变桨控制器上增加功率桨距角发电机转速控制环，使桨距角能够在额定功率以下提前动作；在桨距角发电机转速控制环的比例项中增加非线性增益因子，使得变桨控制能在阵风下快速动作。仿真分析与现场测试结果表明，这2个阵风控制策略能有效地抑制与减少风电机组发电机由于超速带来的停机，一定程度上可以提高风电场发电量，降低风电机组机械载荷，提高电网稳定性。 |

| Abstract: |
| According to the advance and quick action principle of pitch controller in the gust condition and based on the basic structure of variable speed variable pitch control algorithm, a PPGSL(Power Pitch Generator Speed Loop) is added to the basic pitch controller to let the pitch act in advance below the rated power while a nonlinear gain factor is added to the proportional of PPGSL to make the pitch control quick in the gust condition. The results of simulation and field test show that, the proposed two gust control strategies can effectively suppress and reduce the shutdown of wind turbine due to the over-speed, enhance the power output of wind farm to some extent, lower the mechanical load and improve grid stability. |
