摘要
传统的单矢量直接功率控制SDPC(single-vector-based direct power control)以其结构简单和动态响应快等优点在双馈电机DFIG(doubly-fed induction generator)并网发电控制中得到了广泛研究,但同时具有高采样频率、变开关频率和稳态脉动大等缺点。在传统矢量表直接功率控制的基础上,将占空比优化的思想引入双馈电机直接功率控制中,深入研究了双矢量直接功率控制,以期在取得较快动态响应的同时,减低稳态功率脉动。最后搭建了实验平台对3种直接功率控制方法的动静态性能进行了实验验证和比较,为实际应用中控制算法的选择提供了理论和实验依据。
The conventional single-vector-based direct power control(SDPC)has been widely studied in the grid-connected power generation control of doubly-fed induction generator(DFIG)owing to the merits of simple structure and quick dynamic response.However,it also has drawbacks such as high sampling frequency,variable switching frequency and large steady-state ripples.In this paper,on the basis of the conventional vector table-based direct power control(DPC),the concept of duty cycle optimization is introduced into the DPC of DFIG,and the double-vector-based DPC is studied to achieve quick dynamic response while reducing the steady-state power ripples.Finally,an experimental platform was built to verify and compare the steady-state and dynamic performances of three kinds of DPC methods,providing theoretical and experimental reference for the control algorithm selection in practical applications.
