DC CONNECTION SCHEME FOR WINDFARM WITH INTERNAL MVDC COLLECTION GRID
摘要
<p>Connection schemes for offshore power generation with an internal collection grid include a power generation system (22) which includes a plurality of generator-rectifier subsystems (23). The scheme further includes a medium voltage DC (MVDC) collection network with positive pole cables (42) and negative pole cables (44) connected to the DC outputs of the generator-rectifier subsystems (23). At least one offshore substation (50) includes a positive bus bar (54) and a negative bus bar (56) correspondingly connected to the positive pole cables (42) and negative pole cables (44) of the MVDC collection network and a plurality of main DC-DC converters (58). Each main DC-DC converter (58) includes modules connected to the MVDC bus bars (54, 56) and each module has a positive and a negative output with the modules' outputs serially connected to one another. The schemes may also include a high voltage DC transmission system connected to the modules' outputs and at least one DC/AC converter at a substation.</p>
