This paper aims at proving the application of the fault location method based on the Electromagnetic Time Reversal (EMTR) to multi-terminal HVDC (MTDC) networks. In particular, the paper integrates the EMTR fault location technique with the protection scheme recently proposed within the EU project TWENTIES. Further, in view of the peculiarity of the fast protection schemes required by HVDC applications,...
Many point to point HVDC lines are already in operation in several countries. However, the development of multi-terminal DC grids is slowed by the lack of efficient control and protection strategies that can be applied on such grids. This article deals with the protection aspect of those networks. Indeed, the resort to Voltage Source Converters (VSC) changes the constraints since the short circuit...
High Voltage Direct Current (HVDC) grids have a wide potential of development, especially considering the development of offshore wind power plants. In this paper, we consider meshed HVDC grids. Meshing networks increases the fault current. These very high currents are a drawback for the system, and the fault clearing process requires new technologies to break huge direct current. Therefore, high...
