Fault detection in HVDC-connected wind farm with full converter generator

In HVDC-connected wind farms with full converter generator (FCG) the short-circuit currents are mainly governed by the control systems of HVDC and wind generators' converters. This peculiarity requires accurate studies for the design and evaluation of reliable fault detection methods. In line with this need three-phase faults analyses have been performed on a test-case system, using PSCAD/EMTDC, and protection strategies have been proposed and analyzed.
