自适应法与参考方法检测性能的仿真比较

摘要

自适应法与参考方法是两种典型的单相电路谐波电流检测方法。为了了解两种方法（特别是在实际应用时）的优劣,对其进行了仿真比较。仿真结果表明：无论是在理想条件下,还是在实际应用时,参考方法的检测精度明显高于自适应法的检测精度。研究结果对实际应用具有指导作用。%Adaptive method and referenced method are two typical detection methods for harmonic current of singlephase circuit. In order to understand their detection performances, especially, those in actual application, simulative comparisons between them have been done. The simulative comparisons showed that the detection precisions of referenced method are clearly higher than those of adaptive mathod in both ideal conditions and actual applications. The results act an guidance role in actual application.
