| Abstract |
A new application of high temperature superconducting technology for HVDC grids is introduced. The device referred to as "superconducting power filter" (ScPF) aims at increasing the stability of HVDC grids by adding a current-dependent resistance to the grid. In comparison with other stabilization techniques, a ScPF achieves a fully passive stabilization with virtually no losses in nominal operation. To clarify its feasibility for HVDC grids, the HVDC grid test system DCS1 proposed by CIGRE B4 is considered. Using an electrical-thermal model of the device, the stability of the DC grid is numerically assessed depending on the design parameters of the device. The first steps towards an experimental proof of concept are presented. |
