Design of a Surge Arrester Based Load Commutation Switch for Hybrid HVDC Breakers and MVDC Breakers
In this paper, the switching behavior of a combination of series and parallel connected IGBTs with a parallel surge arrester is investigated. The focus is on the application of an auxiliary power electronic switch, referred to as a load commutation switch, for the hybrid HVDC breaker. The switching behavior of a state of the art SPT+ IGBT is compared to the switching behavior of the Bi-Mode Insulated Gate Transistor. In addition to that, design aspects of the LCS are discussed.
Fault Discrimination in Bipolar HVDC MTS Equipped with Bus Bar Breakers
A system-wide valid HVDC MTS protection scheme has been developed for converter and dc-side Circuit Breaker action control. Furthermore, a beneficial earthing scheme for bipolar MTS is presented.
An HVDC Current Flow Controller for Multi-Terminal Grids
This paper proposes a modular and scalable current flow controller (CFC) for meshed High Voltage Direct Current (HVDC) grids. The exchange of active power is performed directly between two DC branches and the circuit can be directly installed at a DC node without any additional AC grid. The CFC is especially suitable for medium CFC voltage ratings. Furthermore, a comparison of different CFCs is performed which all allow an interline power exchange but are designed for different CFC voltage ratings.
