摘要
阐述了永磁直驱风电系统背靠背双脉宽调制(PWM)全功率变流器的电路结构和控制原理,利用Matlab软件建立了该系统的仿真模型,对其稳态和动态性能进行了分析.并构建了永磁直驱风电试验平台和双PWM变流器系统.结果表明:采用双PWM变流器作为永磁直驱风电系统的变流器,可以实现对永磁同步发电机(PMSG)的优良控制,并向电网输送优质的电能.
Circuit structure and control principle of the full power back-to-back dual-pulse-width modulation （PWM） converter for direct-driven permanent magnet synchronous generator （PMSG） based wind power system were described. The system was modeled with the help of software Matlab and the steady-state and dynamic performance of which were then analyzed. Experimental platform of direct-driven PMSG based wind power system and the system of dual-PWM converter were established. Results indicate that the dual-PWM converter, as the converter of direct-driven PMSG based wind power system, has satisfied control performance for PMSG with excellent power quality transmitted.
