This paper shows that it is possible to substantially reduce the rectifier capacitor and filter banks when using diode based HVDC link for the connection of large off-shore wind farms. The considered wind turbines are based on full power power converters. The paper includes a control strategy that allows the wind turbine front-end converters to control the offshore ac-grid voltage and frequency and,...
The filter bank size is one of the main deterrents for the use of otherwise more efficient LCC-HVDC links for the connection of large off-shore wind farms. This paper shows how the HVDC rectifier filter banks can be substantially reduced by taking advantage of the additional control flexibility offered by the use of wind turbines with fully rated converters. PSCAD simulation results are shown where...
