摘要
在分析变速恒频风力发电系统转子变流器组成特点的基础上,提出并实现了一种基于TMS320LF2407A和TMS320VC33双数字信号处理器芯片的新型转子电流混合控制的变速恒频异步风力发电系统,同时对该系统的运行控制、并网控制技术进行了实验研究。该新型转子电流混合控制结构能显著降低转子变流器的硬件成本和控制技术的复杂性,在全速范围内实现输出有功和无功功率的独立调节。实验结果表明,该新型转子电流混合控制结构可以满足变速恒频风力发电机系统的运行要求,同时实现了发电机的输出功率因数可控。
Based on the analysis of rotor converter＇s constituting feature of Variable Speed Constant Frequency （VSCF） wind generator system, another kind of VSCF wind generator system, which adopts a novel rotor current hybrid control system using dual digital signal processor chips TMS320LF2407A and TMS320VC33, is proposed. The experimental research on operation control and synchronization control is conducted. The structure of the novel rotor current hybrid control system can evidently reduce the hardware cost and the complexity of control technique, and can respectively regulate the active and reactive output of the generator system. Experimental results show that the novel rotor current hybrid control system can satisfy the requirement of VSCF wind generator system, and the power factor control of generated power is available.
