Abstract: This paper presents Fault Tolerant Voltage Source Converter for HVDC transmission system based on a hybrid multilevel voltage source converter with ac-side cascaded H-bridge cells. The proposed converter offers a unique feature of dc fault blocking capability (ability to block power exchange between the ac and dc sides during the dc side faults, hence no current flows in converter switches), operational flexibility in terms of active and reactive power control, black start capability, in addition to improve ac fault ride through capability. In this paper, four quadrant operation and voltage support, the ac and dc fault ride-through capabilities of the proposed converter will be demonstrated.
Keywords: AC And DC Fault Ride Through Capabilities, DC Fault Reverse Blocking Capability, Hybrid Multilevel Converter With Ac Side Cascaded H Bridge Cells.
Scope of the Article: Wireless Power Transmission
