MUSIC算法在间谐波信号检测中的应用及优势

摘要

The problem of Interharmonics is one important factor affecting security and stability of power systems. Traditional methods could not be detected in a short sampling time signal harmonics and interharmonics and larger errors. In this paper,a new method based on the idea of MUSIC(Multiple Signal Classification Method) , and simulation were compared with the Burg algorithm,Finally, Verify the superiority of MUSIC.%间谐波问题是影响电力系统安全稳定的重要因素之一.传统方法无法在短采样时间内检测出信号的谐波和间谐波,且误差较大.因而提出了采用空间谱估计算法中的MUSIC算法进行检测,并通过仿真与Burg算法进行比较,验证了方法在短采样时间内检测出信号基波附近间谐波的优势.
