摘要 本文针对电力变压器有源降噪系统的次级路径参数对降噪效果的影响进行研究,提出次级路径时延计算方法。以滤波x最小方均(FxLMS)算法为基础,搭建基于TMS320C6748数字信号处理器(DSP)的变压器有源降噪实验系统,并对比不同次级路径时延下的变压器有源降噪实验效果,就次级路径时延对变压器有源降噪系统降噪性能所造成的影响进行验证。

Abstract:The influence of the secondary path parameters of the transformer active noise reduction system on the noise reduction effect is studied in this paper, and the calculation method of the secondary path delay is proposed. In this paper, based on the filtered-x least mean square (FxLMS) algorithm, an experimental system for transformer active noise reduction based on TMS320C6748 digital signal processor (DSP) is built, and the experimental results of transformer active noise reduction under different secondary path delays are compared. The influence of secondary path delay on the noise reduction performance of transformer active noise reduction system is verified.
