摘要:
邻近谐波或基波的间谐波,是导致电压闪变的直接原因,准确检出该成分,对于改善电能质量具有重要意义.针对真实电网宽带多频的信号特性,提出了一种改进的间谐波分析法—加窗插值MUSIC法,该方法克服了加窗插值和MUSIC算法的局限.Matlab仿真表明加窗插值MUSIC法频率分辨率和精度优于加窗插值,相对传统求根MUSIC不需要估算信号个数,能有效消除伪谱的影响.
Abstract:
Detecting interharmonics for flicker troubleshooting is highly desirable． Whereas these interharmonics are close to harmonic or fundamental component，it is always swamped by the main-lobe of harmonic nearby if the harmonic amplitude is much bigger than interharmonic amplitude，and vice versa． In this paper，an improved interharmonic analysis algorithm is proposed on the basis of the windowed interpolation and the MUSIC method． It is shown by matlab simulation that the new method enjoys higher frequency resolution and is more precise than traditional ones．
