摘要
通过实时、准确地检测谐波和间谐波参数,才能实现谐波补偿装置的最优配置和达到治理谐波和间谐波的目的。针对谐波和间谐波检测中的实时性和高精度参数估计问题,提出了一种基于50%通道交叠的多相滤波器组结构的谐波和间谐波快速检测方法,同时避免了谐波和间谐波落入通道交叠处而降低检测能力的问题。理论分析和仿真结果表明,该方法可以有效地提高检测的实时性,同时保持着高精度,且易于实现。
Only through real-time and accurate detection of harmonic and inter-harmonic parameters can achieve the optimal configuration of harmonic compensation device,as well as achieve the goal of governing harmonics and inter-harmonics.As for the real-time and high-precision parameter estimation during the harmonics and inter-harmonics detection,this paper puts forward a high-precision correction method based on the fast detection of harmonics and inter-harmonics of 50%channel overlapped poly-phase filter structure.Meanwhile,it avoids the problem that detection capacity is reduced when harmonics and inter-harmonics are in overlapped channels.Theory analysis and simulation results show that the proposed method can effectively improve the instantaneity of detection,as well as maintain a high accuracy,and it is also easy to implement.
