摘　　要：为了提高双馈感应发电机(DFIG)滑模控制对抖动的抑制能力,增强抗干扰性能,提出一种新的自适应终端滑模控制策略,增益参数根据滑模面的绝对值进行动态调整,通过调节瞬时有功和无功功率,实现涡轮变速控制,保证高质量电力供给。研究了自适应终端滑模控制算法,给出了DFIG动力学模型。新设计的风力发电转换系统的转子侧使用自适应终端滑模控制,网侧使用直接功率控制。与常规SMC方法进行了实验对比,显示终端滑模控制器的自适应特性能保证更好的瞬态响应,能有效抑制干扰。验证了所提出的自适应终端滑模控制的鲁棒性、稳定性和有效性。In order to improve the ability of chattering suppression of sliding mode control in doubly fed induction generator(DFIG),and enhance the performance of anti-jamming,a new adaptive terminal sliding mode control strategy in which gain parameters could be dynamically adjusted according to the absolute value of the sliding surface,and turbine speed could be controlled by regulating the instantaneous active and reactive power,was proposed to ensure the high quality of power supply.The algorithm of adaptive sliding mode control was studied,and the DFIG dynamic model was given.In new control system,this adaptive terminal sliding mode strategy was used inthe rotor side,the direct power control was used in the grid side.Comparative experiments were done with theconventional SMC.The results show that the adaptive terminal sliding mode controller not only provides a better transient response,but also effectively inhibits a wide range of interference.The robustness,stability and effectiveness of the proposed adaptive terminal sliding mode control are verified.
