This paper analyzes the behavior of a modular multilevel
converter-high-voltage direct-current (MMC-HVDC)-connected
offshore wind power plant (WPP) during dc faults. For
that purpose, detailed models of the dc cable, MMC stations, and
transformers have been used in order to obtain reliable results.
The influence of the WPP control method in the short-circuit behavior
of the HVDC link has also been studied. Results show that
the dynamics of the WPP contribution to pole-to-ground faults
are slightly slower than those of the wind turbines current control
loops. Therefore, the wind turbine front-end converters can be
used to reduce the peak and average value of the fault current
in such a system. Moreover, it has been found that ferroresonant
oscillations can appear in the offshore ac grid when the WPP
delivers constant power during faults. [-]
