Research on Active Noise Reduction System of Transformer Based on Disturbance Tracking Method

文中针对变压器有源降噪系统进行研究分析,主要依据扰动跟踪法来控制变压器的噪声,变压器噪声主要来源于变电站,然而变压器对于无源降噪上,主要是弥补其中的不足,选择控制低频噪声治理,在整体应用价值上,主要结合采集和分析来降低电力变压器噪声信号,明确复杂声波的主要模型,因此变压器的特性和频率是完善扰动跟踪法的变压器有源噪声控制算法。进一步控机和可视化编程实现扰动跟踪控制功能,从而实现噪声信号采集与输出功能,实现有源降噪实验装置。

This paper studies and analyzes the active noise reduction system of the transformer,mainly according to the disturbance tracking method to control the noise of the transformer.The noise of the transformer mainly comes from the substation.However,the transformer is mainly to make up for the deficiency in the passive noise reduction,and choose the control of the low frequency noise to control the whole application value.It mainly combines acquisition and analysis to reduce the noise signal of power transformer and clear the main model of complex sound wave.Therefore,the characteristics and frequency of the transformer are the active noise control algorithm of transformer with perfect disturbance tracking method.The function of disturbance tracking control is realized by further controlling the machine and visual programming,so as to realize the function of noise signal collection and output,and realize the experimental device of active noise reduction.
