Abstract

Highlights: Fault detection in the HVDC-connected wind farm with FCG is proposed. Active power direction and peak current can be used to detect faulty feeder. Current magnitudes information along the section is used to detect faulty section. Other method to detect faulty section is by observing the active power direction. Positive sequence impedance information can also be used to detect faulty section. Abstract: 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.
