The transient response speed of the traditional PI current regulator is slow, and its control bandwidth is narrow.In view of this, the current regulator-based double hysteresis current vector control technology is proposed.Its operating principle is analyzed, and the switch table of double hysteresis cur-rent vector control is derived.The simulation model of current regulator-based double hysteresis current vector control technique is constructed in Matlab/Simu1ink platform.The simulation results show that the proposed current regulator-based double hysteresis current vector control technology has fast dynamic re-sponse speed, and its dynamic performance is superior to the traditional PI current regulator.Therefore, it can meet the speedy adjustment requirements for active and reactive powers of DFIG-based wind tur-bines.
