Resumé

VSC-HVDC grid can be grouped into two different topologies named radial and meshed. The meshed grid is more flexible, reliable and secure because there are more power flow paths between two or more converters, thus it becomes one of the most potential solutions for the Europe Supergrid. However, the restoration of such a system is still a challenging issue. In this paper, an automatic restoration strategy is presented to recover the grid after a contingency. Compared with other restoration strategies, this strategy has two advantages. First, it has a strong ability to automatically recover the grid system in a shorter time. Second, it realizes the coordination of restoration and grid control strategy thus over or under voltage caused by power imbalance during restoration period is avoided. The effectiveness of the proposed strategy is tested in the PSCAD/EMTDC for a pole to pole fault.
