摘要:为了保证全额变频器能高效工作,引入了机侧变流器电压闭环控制系统,并提出了网侧和机侧的双环控制策略.在桨距角控制方面,考虑接地故障和风速变化对系统的影响程度不同,设计了通过判断故障来调整输入控制信号的新型桨距角控制器.实验仿真结果表明,带全额变频器的感应风力发电机能满足风力发电机本身的控制要求,且能输出满足电网要求的恒频稳定电能.

关键词: 全额变频器, 风力发电机, 可变风, 桨距角

Abstract: For smooth operation of the power system regardless of the various wind speed and system ground faults, the full rated inverter is applied in wind generator. This inverter has double loop control on both grid side and generator side. It is note that the voltage closed-loop control as an innovative use is attributed for grid side control. The pitch angle controller is designed to meet both various wind and system faults according to the input signal. Simulations for evaluated the performance are conducted and the results verify that the proposed control strategy with the high efficiency satisfies requirements both WT control and the quality of the power grid.

Key words: full rated inverter, wind generator, various wind, pitch angle
