Abstract

This paper presents a DC voltage control strategy for enhancing the fault-ride-through (FRT) capability of wind farms comprising of fully rated converter permanent magnet synchronous generators (FRC-PMSGs) connected to multi-terminal high voltage direct current (MT-HVDC) grids through modular multi-level converters (MMCs). The proposed FRT strategy is implemented on a master controller located in the offshore AC substation of each wind farm. The underlying issue addressed via the scheme relates to overvoltages in the HVDC links when the power transfer is disrupted due to faults occurring in the AC onshore grid. The corresponding Matlab/Simulinkr model has been validated using transient simulation, while the practical feasibility of the controller is demonstrated utilising Opal-RT© real-time hardware platform.
