摘要/Abstract

摘要： 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30kV·A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。

Abstract: Combined with the control requirements of hydraulic wind turbine LVRT, in order to realize power rapid adjustment in the processes of LVRT, a control method of LVRT was proposed based on pressure control, namely adding pressure control loop in the original LVRT control loop. Simulations were carried out based on AMESim and MATLAB/Simulink, and control method was verified by the experiments on the 30kV·A hydraulic wind turbine platform. Finally, it shows the proposed control method may realize the fast adjustments of power, and effectively restrain the grid-connected speed impacts, which lays a theoretical foundation for the engineering applications of the hydraulic wind turbines.

Key words: wind power generation, hydraulic transmission, low voltage ride through(LVRT), pressure control, impact suppression
