Abstract

This paper introduced the control strategy of back-to-back full-scale PWM converter in direct-driven wind power system with PMSG (Permanent Magnetic Synchronous Generator). A simulation model has been built to demonstrate the maximum wind energy capture, DC voltage stability and decouping control of active and reactive power. In addition, the dynamic responses of system parameters during typical voltage sag and the role of dumping load at DC side have been tested. The simulation result shows that direct-driven wind power system has good capability of low voltage ride through.
