DFIG的SVM-IPC与SVM-DPC比较

为比较间接功率控制（indirect power control,IPC）和直接功率控制（direct power control,DPC）的控制特点,提出了双馈感应发电机（doubly-fed induction generator,DFIG）的间接功率控制（IPC）和直接功率控制（DPC）策略。首先提出采用空间矢量调制（space vector modulation,SVM）的SVM-IPC策略,该策略通过对转子电流的直接控制间接实现对定子有功和无功功率的解耦控制;其次提出基于SVM的SVM-DPC策略,该策略不通过电流控制环节,直接实现定子有功功率和无功功率的解耦控制。分析结果表明,SV...

Summary:为比较间接功率控制（indirect power control,IPC）和直接功率控制（direct power control,DPC）的控制特点,提出了双馈感应发电机（doubly-fed induction generator,DFIG）的间接功率控制（IPC）和直接功率控制（DPC）策略。首先提出采用空间矢量调制（space vector modulation,SVM）的SVM-IPC策略,该策略通过对转子电流的直接控制间接实现对定子有功和无功功率的解耦控制;其次提出基于SVM的SVM-DPC策略,该策略不通过电流控制环节,直接实现定子有功功率和无功功率的解耦控制。分析结果表明,SVM-IPC具有良好的稳态性能,但动态响应能力取决于PI参数的优化程度;SVM-DPC不仅稳态性能好,而且具有快速的动态响应能力。实验结果验证了提出策略的可行性和正确性。

The indirect power control（ IPC） and direct power control（ DPC） for doubly-fed induction generator（ DFIG）-based wind energy generation system were presented to compare the control performance of IPC and DPC. Firstly,the indirect power control strategy using space-vector modulation（ SVM-IPC） was proposed,which indirectly achieved decoupling control between active power and reactive power on stator by direct controlling to rotor current. Secondly,the direct power control strategy using space-vector modulation（ SVM-DPC） was presented. It directly achieved decoupling control between active power and reactive power witho
