摘要
研制了一套基于TMS320LF2407A和TMS320 VC33双DSP的风力发电系统。在分析了该系统控制方法的基础上,建立了交直交变频器网侧电压定向以及转子侧定子磁场定向的矢量控制系统模型。对系统的变速恒频控制、并网控制技术进行了实验研究,结果表明,该系统能够在发电机允许的速度范围内实现软并网,输入输出有功、无功功率可以独立调节,适合于兆瓦级风力发电系统。
A doubly-fed induction generator wind power system controlled by TMS320LF2407A and TMS320VC33 was developed. Based on the analysis of control strategy of the system, this paper used respectively voltage oriented and stator flux oriented vector control in grid side and rotor side of the converter. Some control methods, such as variable speed constant frequency(VSCF) technology, synchronizing control, are studied experimentally. Experimental results show that soft synchronizing can be implemented when the generator speed is within the permitted range and active/reactive power can be regulated independently. And the system can be applied to wind power generation system with megawatts level rated power.
