Small-Capacity Experimental Prototype of VSC-HVDC for Offshore Wind Farm

Abstract:

VSC-HVDC is one of the proven solutions for the transmission problem of offshore wind power. The structure of back-to-back with two-level converters was adopted for wind farm and grid side, in this paper. PI controllers and SVPWM modulation strategy were used for control system. The double closed-loop vector control method was used for converters of two ends, one end controlling DC voltage and the other controlling active power. The reactive power was controlled by both ends independently. The designed system was verified by simulation and experiment based on a small-capacity experimental prototype.
