摘要：
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 30 kV·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. © 2017 Chin.
