Simulation on power characteristic of UHVDC during commutation failure and DC block

UHVDC commutation failure and DC block need to be studied in detail, for they will evidently affect the safety and stability of AC power grid. Firstly, the main circuit and control system are studied and analyzed in depth. Then, the simulation model is established in PSCAD software. After that, the curves of commutation failure and DC block in different cases are obtained. Finally, the correctness of this simulation platform is verified by comparison of some recording curves.
