改进型PR控制器应用于双馈风力发电系统
|
摘要
此处提出将改进型比例谐振(PR)控制器应用于双馈感应风力发电(DFIG)系统电流环控制的并网控制策略,无需引入与电路参数有关的交叉耦合项且减小了坐标变换带来的控制复杂性,可实现对电流的稳态无静差追踪及单位功率因数控制,提高了系统的鲁棒性。最后将PR控制器数字化应用于11 kW DFIG实验平台,实验结果表明所提控制策略应用于DFIG系统具有优良的动态性能且能够有效抑制谐波。
A cutting-in control strategy is proposed base on applying improved proportional resonant(PR) controller to the current loop control of doubly fed induction wind power generation(DFIG) system.There is no need to introduce the cross coupling related to the circuit parameters and reduce the control complexity caused by the coordinate transformation.The steady-state non-stationary tracking of the current and unit power factor are realized to improves the robustness of the system.Finally,the digitalization of the PR controller is applied to the 11 kW DFIG experimental platform.Experimental results show that the proposed control strategy is applied to DFIG system with excellent dynamic performance and effective suppression of harmonics.
