| 摘 要： | 针对大型风电机组动态载荷分布不均问题,提出基于线性二次高斯控制的独立变桨控制策略,通过建立整机系统模型和线性二次高斯算法（LQG）控制器,利用SIMPACK软件与Simulink进行联合仿真,计算比较不同控制方式下风力机主要零部件所受的载荷。计算结果表明,相对于统一变桨,独立变桨控制方式能够更好地稳定输出功率和载荷波动。相对于传统的PI统一变桨控制,LQG独立变桨控制能更好地降低风力机主要零部件的疲劳载荷。

| Abstract: | In order to solve the uneven dynamic load problem of large-capacity wind turbines, the Linear Quadratic Gaussian (LQG) scheme is proposed, which can calculate and compare the loads borne by main components of wind turbine under different control modes based on the wind turbine model and LQG controller through co-simulation of SIMPACK and Simulink software. The simulation result shows that, compared with the collect pitch control strategy, the independent pitch control strategy is superior in stabilizing the output power and load fluctuation. Compared with the PI collect pitch control, the LQG independent pitch control can better reduce the fatigue load of main components of wind turbine. |
