Abstract

Improper setting of wind turbine control parameters can cause the damping of the wind turbine to weaken and cause free oscillation. In order to take reasonable measures to suppress the oscillation of wind turbines, it is necessary to study the mechanism of the influence of wind turbine control parameters on unit damping. Taking a direct-drive wind turbine as an example, firstly, taking into account the proportional coefficient Kppll and integral coefficient Kipll of the phase-locked loop control, the proportional coefficient Kp1 and integral parameter Ki1 of the internal loop control of the grid side converter, the transient energy function of the direct-drive wind turbine is derived, and the influence mechanism of different control parameters on the transient energy and damping of the unit is analyzed; Define the energy consumption power and damping influencing factors of the unit, and quantitatively analyze the impact of different control parameters on the damping of the unit; Finally, model and analyze on the PSCAD/EMTDC platform, and deeply analyze the impact of control parameters on unit damping through changes in energy consumption power. The simulation results show that within a certain range, the control parameters of the inverter decrease, the energy consumption power of the direct drive unit increases, and the damping weakens; As the control parameters of the phase-locked loop increase, the energy consumption power of the unit increases, and the damping weakens; When the unit change rates of control parameters Kp1,Ki1,Kppll,and Kipll are the same, the impact on unit damping is in descending order of Ki1,Kp1,Kppll and Kipll.
