Average model of MMC with full-bridge sub-modules for blocking situation

This paper proposes a fast electromagnetic simulation model based on sub-module average modelling. The model can effectively reflect the behaviour of sub-modules and ensure high precision in time domain simulation, and greatly improve the simulation speed. By changing the corresponding control strategy, the characteristics of the submodule under the blocking situation can be simulated. This provides a simulation method for further study of MMC under fault condition. The correctness and feasibility of the model are verified on the PLECS simulation platform.
