Hydraulic Wind Turbine Low Voltage Ride Through Hierarchical Control

doi:10.3901/JME.2018.20.096

Abstract

Abstract: In order to improve the adaptability of the power grid and the low voltage ride through ability of the hydraulic wind turbine, a new method was proposed based on the hierarchical control. The top level control based on wind turbine pitch control, the middle level control based on variable motor swing angle and the bottom level control based on throttle valve were proposed, and the control laws were designed. In order to achieve multi-variable coordinated control of the hydraulic wind turbine, the optimization goal is to minimize the energy consumption of the wind turbine and the throttle valve, maximum the inertia energy of the wind turbine, the linear quadratic regulator algorithm is applied to plan the multi-objective control law. The simulation analysis is carried out by AMESim and MATLAB/Simulink software, and the control law is verified by the semi physical experiment platform of the hydraulic wind turbine. The results show that the proposed control method can effectively reduce the residual energy of wind turbine in the process of LVRT, reduce the impact to generator and improve the adaptability of hydraulic wind turbine.
