High-voltage direct-current (HVDC) grid protection strategy has a broad research scope. Many approaches were developed during restrain DC fault currents. The modular Multilevel Converters (MMCs) are used in the proposed research work. In this method, DCCBs is temporarily by-passed at MMC sub-modules. When the fault is isolated at DCCBs, MMCs will remain at normal state. In this, two actions are observed, they are MMC blocking and no corrective action. A fault algorithm detection & distinction is being used and their effect forth M MC by-passage is observed. Results of simulation show that synchronization of MMCs & DCCBs significantly decreases current of dc fault.
