雙饋風(fēng)力發(fā)電系統(tǒng)反推控制策略的研究
[Abstract]:The doubly-fed induction motor used in doubly-fed wind power generation system has the advantages of simple structure, high power generation efficiency, simple installation and so on. In addition, this kind of system also has certain defects, and it itself has nonlinear. The strong coupling characteristics make the design of the controller more difficult and reduce the possibility of high performance operation of the system. In this case, a simple control algorithm which can improve the performance of the system emerges as the times require. In this paper, the mathematical model of doubly-fed induction motor in three-phase static coordinate system is introduced. In order to make it more convenient to study, coordinate transformation is needed to simplify the model, and the mathematical model of the system in two-phase synchronous rotating coordinate system is established. On this basis, the vector controller is designed, and the simulation results lay a foundation for the comparative analysis of the paper. In order to improve the defects of vector control in the control of the system, we began to study backstepping control. The backstepping control usually starts with the control target of the system and is used in combination with the Lianov stability theory. The controller can not only ensure the stability of the system, but also realize the global adjustment or tracking of the system. Meet the expected performance targets. In this paper, the backstepping control strategy based on direct power and the backstepping control strategy based on vector control are studied. The former takes power tracking as the control target to design the backstepping controller. The latter takes current tracking as the control target and begins to design the backstepping controller. In this paper, a simulation model is built on Matlab/Simulink platform to carry out theoretical analysis. After the simulation is completed, the simulation waveform of doubly-fed wind power generation system controlled by vector controller is compared with that of doubly-fed wind power generation system controlled by backstepping controller, and it can be found that both control methods can realize the decoupling of power. Tracking control, but the simulation waveform response speed of the backstepping control strategy is faster, and when the parameters change, the response waveform of the backstepping control strategy is more stable and more robust to the parameter change.
