Abstract
The possibility to connect offshore wind turbines
with a collection network based on Direct Current (DC), instead
of Alternating Current (AC), gained attention in the scientific and
industrial environment. There are many promising properties
of DC components that could be beneficial such as: smaller
dimensions, less weight, fewer conductors, no reactive power
considerations, and less overall losses due to the absence of
proximity and skin effects.
This work describes a study about the simulation of a Medium
Voltage DC (MVDC) grid in an offshore wind farm. Suitable
converter concepts are identified and the power flow in steady-state
and during fault conditions is investigated. The efficiency of
the network is determined in full-load conditions. Furthermore,
key design aspects of such a grid are illustrated and issues
regarding ripple current and converter design are treated. The
overall efficiency of the MVDC grid is determined to 94%.
