Abstract

High-voltage direct current (HVDC) transmission has become a promising technology for the future electrical power grid, especially for the concept of Super Grid. There is a trend to connect the existing simple point-To-point HVDC lines together as multi-Terminal HVDC (MTDC) network for the sake of sustainable power supply. However, problems occur when it comes to protecting this complex electrical system because the current protection methods have shortcomings. Meanwhile, there are studies on developing protection schemes based on wavelet transform (WT), which are suitable for the point-To-point networks, but are insufficient for the MTDC networks. Therefore, this paper has conducted the transient analysis of a MTDC network after faults and presented a new WT-based protection. A protection scheme is then proposed. With certain thresholds, it has good selectivity of faults that are outside the protection zone. This protection scheme is validated by simulation on the PSCAD/EMTDC platform.
