Abstract
Offshore HVDC-connected wind farms can with advantage let the wind plant power
collection network become DC, rather than AC, promising reduced electrical losses, lower
bill-of-material cost and undimished functionality. However, no standards exist for an
offshore medium-voltage DC power collection cable-based system, routing power from
MVDC wind turbines all the way to the HVDC export cable. To progress, it is therefore
important to establish some common reference for the design and performance of the
components needed in an MVDC collection network. Any suggested MVDC collection
solution must be possible to characterise and evaluate through a series of case studies. This
paper proposes a methodology to simulate the MVDC collection network and thereby find
suitable ratings of its components. The methodology is intended to allow studies on any
configuration of the MVDC power collection, regardless of choice of turbine converter circuit,
MVDC cable configuration, use of DC circuit breakers, substation converter circuit, control
and protection. The paper will present the necessary list of studies, and include examples of
simulation results for an examplary MVDC wind power plant.
