摘要：
This paper proposed a more flexible control strategy for voltage source converter based high voltage direct current (VSC-HVDC) transmission to improve the performance of the AC/DC hybrid transmission systems with wind farms integrated. A novel AC voltage and load angle control approach was designed for the wind farm side VSC. In AC/DC hybrid transmission mode, constant active power control was achieved by regulating the load angle between the voltage of wind farm AC bus and the output voltage of wind farm side VSC. In simplex VSC-HVDC transmission mode, the voltage of wind farm AC bus was automatically modulated to have constant amplitude and constant frequency to achieve the synchronous transmission of fluctuating wind power. The control approach requires no switching control actions to accommodate mode change. Moreover, damping to resonances in the system was improved by additional high-pass filter. A new direct current vector control approach was applied to the grid side VSC to regulate the DC voltage to reference value. The AC/DC hybrid transmission systems connected wind farms equipped with squirrel cage induction generator (SCIG) and doubly fed induction generator (DFIG) were respectively modeled and simulated by PSCAD/EMTDC. The simulation results considering a series of operation conditions prove the validity and feasibility of the proposed approaches. ©2014 Chinese Society for Electrical Engineering
