Simulation of VSC Based HVDC Transmission System under Fault Conditions
Journal Title: International Journal of Science Engineering and Advance Technology - Year 2014, Vol 2, Issue 12
Abstract
Voltage-source-converter high-voltage dc (VSCHVDC) transmission systems have evolved from simple two-level converters to neutral-point clamped converters and then to true multilevel converters such as modular converters. Present VSC-HVDC transmission systems rely on their converter station control systems and effective impedance between the point-of-common-coupling (PCC) and the converter terminals to ride-through dc side faults. A VSC-HVDC transmission system is a candidate to meet these challenges due to its operational flexibility, such as provision of voltage support to ac networks, its ability to operate independent of ac network strength therefore makes it suitable for connection of weak ac networks such as offshore wind farms, suitability for multi terminal HVDC network realization as active power reversal is achieved without dc link voltage polarity change, and resiliency to ac side faults. This paper proposes a new breed of highvoltage dc (HVDC) transmission systems based on a hybrid multilevel voltage source converter (VSC) with ac-side cascaded H-bridge cells. This paper assesses its dynamic performance during steady-state and network alterations, including its response to ac and dc side faults by using MAT Lab/Simulink.
