摘要：

Permanent magnet synchronous generator (PMSG) based offshore wind farm is connected to the onshore grid by voltage source converter (VSC) HVDC link. The wind farm side VSC controls the AC voltage, and grid side VSC controls the reactive power and DC link voltage. This paper presents a non-linear control method for improving the robustness of the controller for VSC-HVDC link. A hybrid controller is designed using sliding mode control (SMC) and proportional-integral (PI) control. Mathematical modeling of the hybrid controller is presented. This hybrid controller has the capability of Fault Ride Through and transient stability of VSC-HVDC link. This hybrid controller is simulated using the MATLAB/Simulink software and it is observed that the controller provides better performance. Transient stability is ensured by creating a symmetrical fault at the grid side in the simulation.
