    结合液压型风力发电机组低电压穿越的控制要求,以实现低电压穿越过程中的功率快速调整为控制目标,提出了一种基于压力控制的低电压穿越控制方法,即在原有低电压穿越控制环的基础上加入压力控制环.通过AMESim和MATLAB/Simulink软件搭建仿真平台进行联合仿真,并依托30k VA液压型风力发电机组半物理仿真实验平台进行实验验证.结果表明,所提出的控制方法既可实现功率的快速调整,也能有效地抑制并网转速的瞬态冲击. Combined with the control requirements of low voltage crossing of hydraulic wind turbine to achieve the rapid adjustment of power in the process of low voltage crossing as the control target, a low voltage crossing control method based on pressure control is proposed, that is, in the original low voltage crossing control loop Based on the AMESim and MATLAB / Simulink software, the simulation platform was established and simulated by the semi-physical simulation platform of 30k VA hydraulic wind turbine. The results show that the proposed control method can be To achieve rapid adjustment of power, but also can effectively inhibit the transient speed of the network speed.
