摘要:
文章提出一种并网型双馈风力发电机(DFIG)适应低电压穿越(LVRT)工况的无速度传感器控制方法。给出了基于定子静止坐标系和转子旋转坐标系的DFIG矢量控制模型,分析其正常工况和LVRT工况下转子电压特性,并介绍了比例积分谐振(PIR)控制器的特点;提出了LVRT工况下转子侧变流器应采取的控制策略。为了解决LVRT工况下转速估算波动大的问题,提出采用PIR代替PI作为闭环自适应控制器,用于基于转子电流的模型参考自适应系统(MRAS)DFIG转速的辨识方法中。为验证理论分析的正确性,以2.5 MW的DFIG
Abstract:
It presented a speed-sensorless control method of DFIG to adapt to LVRT operation condition. Firstly, a DFIG vector control model based on stator coordinate and rotator coordinate was given, characteristics of rotor voltage in normal working condition and LVRT condition were analyzed, and feature of proportional integral resonant controller (PIR) was introduced. Thus it obtained a control strategy of rotor side converter that should be taken in LVRT condition. In order to decrease error band of the estimated rotor speed in LVRT condition, a close-loop adaptive controller based on PIR instead of PI was proposed to use in the method of speed identification of DFIG which based on the model reference adaptive system on the basis of rotor current. To verify the correctness of theoretical analysis, 2.5 MW DFIG was used as an example to establish a simulation model. Simulation results show that, both in normal operation and LVRT conditions, estimated rotor position can track the actual value accurately in different speeds and powers, which can insure the accuracy of active / reactive power control, and the feasibility of this scheme is feasible.
