摘要： A power generation system includes at least one generator having at least two sets of stator windings, an active rectifier comprising power cell based modular converters associated with each set of generator windings. Each set of windings is connected to an AC voltage side of the associated active rectifier, with each active rectifier having a positive DC voltage output and a negative DC voltage output. The DC voltage outputs of active rectifiers are connected to each other in series. A medium voltage DC (MVDC) collection network comprises positive pole cables and negative pole cables, wherein each positive pole cable is connected to the positive DC voltage output of a first active rectifier and each negative pole cable is connected to the negative DC voltage output of a last active rectifier. A substation receives the negative and positive pole cables of the MVDC collection network for further transformation and transmission.

摘要： Connection schemes for offshore power generation with an internal collection grid include a power generation system which includes a plurality of generator-rectifier subsystems. The scheme further includes a medium voltage DC (MVDC) collection network with positive pole cables and negative pole cables connected to the DC outputs of the generator-rectifier subsystems. At least one offshore substation includes a positive bus bar and a negative bus bar correspondingly connected to the positive pole cables and negative pole cables of the MVDC collection network and a plurality of main DC-DC converters. Each main DC-DC converter includes multiple modules connected to the MVDC bus bars and each module has a positive and a negative output such that the modules' outputs are serially connected to one another. The schemes may also include a high voltage DC (HVDC) transmission system connected to the modules' outputs and at least one DC/AC converter at an onshore substation.

摘要： The present invention discloses a coordinated control method for power distribution system with DC bus electrification scheme and apparatus thereof. The method comprises: detecting what kind of disturbances occurs, and at least one of following steps: restoring the voltages of the failed DC buses if power loss is detected on the DC buses due to temporary or permanent failures of upstream power supplies; controlling the voltage of the abnormal DC buses if overvoltage or under-voltage is detected on the DC buses due to internal or external disturbances; and supporting the voltages of the abnormal AC buses if overvoltage or under-voltage is detected on the AC buses due to internal or external disturbances. The methods and apparatus can further improve the fault-ride-through capability for power plant under external or internal disturbances, and facilitate smooth automatic switching process between two DC buses etc.
