A Black Start Scheme Based on VSC-HVDC Tie Line

Abstract

Abstract: A black start scheme based on voltage source converterbased HVDC(high voltage direct current)(VSC-HVDC) tie line was proposed. The ability of VSC-HVDC to softly energize major power system equipment is proved through simulation by PSCAD software. The voltage and frequency control ability of VSC-HVDC can ensure the process of restoration of the black system to be smoothly without inrush current and transient over voltage. The simulation results indicate that VSC-HVDC tie line is ideal to import black start power by using soft energizing control strategy and the proposed scheme of black start is feasible.

Key words: HVDC transmission technology, high voltage direct current based on voltage source converters(VSC-HVDC), black start, soft energizing
