Abstract

The grid-connected system of grid-based permanent magnet wind turbines has the problems of fault current and transient instability under the condition of grid fault

and the traditional grid-based fault ride-through control strategy is difficult to apply

which makes it difficult to maintain the operation of the grid before and after the fault. To this end

a fault ride-through control strategy for grid-forming permanent magnet synchronous wind turbine grid-forming wind turbine permanent magnet synchronous generator（GFM-WTPMSG） based on active power command and virtual impedance adjustment was proposed. Firstly

a mathematical model of grid-forming permanent magnet synchronous wind turbine based on virtual synchronous control was established. Then

according to the fault current threshold and transient power angle stability constraints

the control strategy under different grid voltage drop depths was proposed based on power command optimization and adaptive virtual impedance adjustment. Finally

the effects of different power commands and virtual impedances on the transient stability were simulated

and verified based on the RT-LAB hardware-in-the-loop simulation platform

the results show that the proposed control strategy can effectively reduce the fault current to the threshold range and improve the transient stability of the grid-connected system

and realize fault ride-through under the control of the grid-based structure.
