Modular Multilevel Converter DC Fault Protection [PDF]
IEEE Transactions on Power Delivery, 2018 High voltage direct current grids will require the development of dc protections that provide fast fault isolation and minimize the disturbance caused to the existing ac power networks. This paper investigates how the dc fault recovery performance of a half-bridge modular multilevel converter (HB-MMC) is impacted by different dc protection design ...
