Abstract

In order to simulate the transient characteristic of the MMC integrated power network accurately

it needs to study the electromagnetic transient simulation technology include the structure

control-protection strategy of MMC

to adapt the application of the new generation technology of power electronics in power system.By the user-defined model of Pscad/EMTDC

the solution for precise modeling of MMC and its control-protection is proposed.Taking into account the characteristic of MMC and its control-protection

the transient modeling with C program interfacing to Pscad/EMTDC for MMC is presented.The overall structure of modeling is designed firstly.Combined with the user-defined component and modular modeling mode

MMC and its control-protection is modeled by some functional modules

and the model of power network with MMC integrated is constructed.The dynamic simulation is conducted

and the results show that it can simulate the dynamic process of sub module voltage

control of MMC

etc.

validity.The MMC model can adapt to different applications

which can be used for electromagnetic transient analysis and control-protection testing for flexible AC transmission and VSC-HVDC based on MMC.
