基于TDA-ESPRIT的电力系统间谐波检测

摘要

提出结合了时域平均技术(Time-Domain Averaging,TDA)的旋转不变原理的信号参数估计(Estimation on Signal Parameters via Rotational Invariance Techniques,ESPRIT)法,有效提高r计算效率,仿真结果表明,其计算精度也在可以接受的范围内.%This paper presents the ESPRIT method which is combined with time-domain averaging (TDA), and the method can effectively improve the computational efficiency. The simulation results show that the calculation accuracy is also within the acceptable range.
