摘　　要：在满足载荷平衡和稳定运行条件的基础上,为减小双风轮风电机组在过渡区的疲劳载荷,并确保双风轮协调配合以达到最佳功率,提出基于原始-对偶内点法的过渡区两段式变桨距优化协调控制策略。在MATLAB/Simulink中通过阶跃风验证了所提策略的快速性和准确性。进一步建立湍流风模型下的双风轮风电机组并网仿真系统,验证了所提策略的可行性。设置评价指标量化对比所提策略与普通变桨控制,结果表明采用所提策略可缩短过渡区超速时间,减小疲劳载荷,有效降低过载程度。On the basis of satisfying load balance and stable operation condition,in order to reduce the fatigue load in the transition zone of dual-rotor wind turbine and ensure the coordination between two rotors for optimal power,an optimization coordination control strategy for two-stage variable pitch in transi-tion zone is proposed based on the primal-dual interior point method.The rapidity and accuracy of the pro-posed strategy are verified through step wind simulation in MATLAB/Simulink.Further,a grid-connected simulation system of dual-rotor wind turbine under turbulent wind model is built,verifying the feasibility of the proposed strategy.An evaluation index is set to quantitatively compare the proposed strategy and the common variable pitch control,and the results show that the proposed strategy can shorten the overspeed time in the transition zone,reduce the fatigue load,and effectively mitigate the overload degree.
