摘要

为提高双馈感应风力发电机的控制性能

提出了一种基于反推算法的直接功率控制(BS-DPC)策略。讨论了在平衡电网条件下BS-DPC的基本原理

以及不平衡电网条件对BS-DPC的影响

并提出了针对不平衡电网条件的BS-DPC新的控制目标和改进控制策略。在平衡电网条件下

对双馈感应风力发电机基于传统查询开关表的直接功率控制(LUT-DPC)、矢量控制(VC)和BS-DPC进行了仿真和实验研究

结果证明

BS-DPC在继承了LUT-DPC优异动态性能的同时

可获得恒定开关频率

并减小电流谐波和功率波动

具有良好的稳态性能;不平衡电网条件的仿真和实验研究同样证明了改进BS-DPC策略的正确性和有效性。

Abstract

In order to improve the operating performance of doubly-fed induction wind turbines

this paper proposes a direct power control (DPC) based on backstepping algorithm (BS-DPC). Firstly

a brief introduction of backstepping control is presented and the basic principle of BS-DPC is discussed in detail

then the comparative research and analysis on simulation and experimental results of look-up table DPC (LUT-DPC)

vector control (VC) and BS-DPC under balanced power grid situation are proposed. The BS-DPC not only inherits excellent dynamic performance from traditional DPC

but also has excellent steady performance and decreases harmonic current and power pulsation with constant switching frequency. Secondly

the influence of unbalanced power grid on the BS-DPC is discussed

and then new control objectives and an improved control strategy based on BS-DPC are proposed. Simulation and experimental results verify the effectiveness of improved BS-DPC under unbalanced power grid condition as well. This work is supported by National Natural Science Foundation of China (No. 51377141) and Zhejiang Provincial Natural Science Foundation of China (No. LY13E070001).
