基于无变压器型混合有源滤波器的快速重复控制策略的研究
|
摘要
混合型有源电力滤波器(HAPF)需要具有稳态精度高和动态响应快的特点,为此根据无变压器混合有源电力滤波器(TLS-HAPF)拓扑结构,提出了一种基于快速重复控制(RC)的改进型控制策略,即比例积分控制(PI)和快速RC两部分相融合。在dq同步旋转坐标系下,这种控制策略不仅可以很好地抑制由非线性负载产生的6n±1次谐波,同时还具有动态响应速度快、占用存储空间小等特点。基于时域法设计了复合控制器的控制参数;分析了其稳态性能和动态性能;并相对于传统控制策略进行了对比性仿真和实验。结果表明,所提出的控制策略在不改变原系统稳态精度的情况下,能够有效提高系统的动态响应速度。
High steady-state control accuracy and fast dynamic performance are crucial technical characteristics for hybrid active power filter(HAPF), therefore, according to the topological structure of transformerless hybrid active power filter(TLS-HAPF), an improved control strategy based on fast repetitive control(RC) is proposed in this paper, which includes proportional-integral(PI) and fast RC. The controller is implemented in a positive-rotating synchronous frame, where all6 n±1 order harmonics of nonlinear loads can be well suppressed, meanwhile, fast dynamic response is achieved and minimal storage space is occupied. Based on the time domain method, the control parameters of the compound controller are designed; its steady state performance and dynamic performance are analyzed in detail. Compared with the traditional compound control, the proposed control strategy on improving RC is of excellent steady-state tracking performance and faster transient response, which is verified by simulation and experimental results.
