Abstract :
In order to design and test the control algorithms of the actual direct-drive wind generation system (DDWGS) with a permanent magnet synchronous generator (PMSG), it is necessary to reproduce the dynamic performances of wind turbine and PMSG in the lab. After the analysis of the aerodynamic, mechanical model of wind turbine and the electrical model of PMSG, a novel simulator based on three-phase voltage source inverter and DSP for a DDWGS with PMSG is proposed in this paper. Based on Park´s transformation, double closed-loop PI control algorithm and space vector PWM, the proposed simulator which eliminates electro-mechanical parts can simulate the external mechanical and electrical characteristics of PMSG. The simulation and experiment results show that the proposed simulator can accurately simulate the external mechanical and electrical characteristics of the actual DDWGS with PMSG under static and dynamic conditions.
