Abstract

Three possible strategies to achieve Fault Ride-Through of offshore wind farms connected through voltage-sourced converter (VSC) based HVDC links are investigated in this paper. Dissipation of excess energy by a braking resistor, fast wind power reduction by voltage modulation and a combination of these two are analyzed. The studies are performed in a four-terminal HVDC grid connecting two 1000 MW wind farms comprised of variable-speed full scale converter wind turbines. Simulation results demonstrate improvements in the performance of the synergistic approach (coordinated operation of the first two strategies). This type of analysis can aid in the design of cost-effective FRT schemes of the envisioned HVDC multiterminal systems.
