A Study on the Black Start Capability of VSC-HVDC Using Soft-Starting Mode

A good black-start scheme is important and necessary to resume power supply fast and efficiently. In this paper, the advantages of VSC-HVDC as black start power are analyzed. The ability of VSC-HVDC soft-starting major power system equipments is proved by software PSCAD/EMTDC. Simulation waveforms during soft-starting are illustrated. These plots have described the good voltage and frequency characteristics of VSC-HVDC. Furthermore, the transition from black start control to normal power flow control is discussed. Simulation results indicate that VSC-HVDC is an ideal black start power by using soft-starting mode.
