Abstract:

The aim of this project is to develop a novel generation of High Voltage DC (HVDC) transmission systems that use hybrid multi-level Voltage Source Converters (VSC) and Half Bridge (HB) cells that are AC cascaded. The operating robustness of VSC systems, Auto- Start capacity, active and reactive power regulation and enhanced ability to ride-through ac fault, and during dc side faults, current limiting capability are only a few of the unique features of the HVDC system. A VSC-HVDC has modular multilevel converters has a broader active and reactive power capability curve than one that uses, which primarily results in improved signal quality and a shorter signal channel length (lower footprint). To ac and dc faults a possibility of this HVDC system is its reaction. Dynamic performance is evaluated in steady-state.
