Abstract :
The purpose of this paper is to provide the design guide line of the module capacitor, the arm inductor and the DC inductor in Modular Multilevel Converter (MMC). Especially, this design method is proposed for the MMC to have the DC fault ride-through capability in Multi-terminal HVDC system. An MMC system connected to two DC grids and an AC grid is formulated according to the design guide line and the performance of the MMC system has been analyzed through computer simulating. The rationality of the proposed guide line has been confirmed by the simulation results.
