This paper presents the application of a Full-bridge modular multi-level converter (FB-MMC) to tap an existing LCC-HVdc system. During faults, the dc voltage of the FB-MMC is controlled to reduce the fault current instead of blocking the converters. Electromagnetic Transient Simulations performed with PSCAD has been used to demonstrate the performance of the proposed system. Control strategies have...
Manitoba Hydro is currently making plans for the development of Bipole III (BPIII), a 2300MW, +/-500kV HVdc Bipole that will run from Northern Manitoba to the Load centre in the south over a length of approximately 1300km. Both LCC and VSC options are considered for the new BPIII HVdc scheme [1]-[2]. One of the features being investigated is the option to parallel the new Bipole III converters with...
