Abstract: For deficiencies of conventional passive methods for substation noise control, a new method of substation noise control which combines artificial neural networks and notch filter is presented in this paper. Firstly, substation noise is theoretically analyzed. Then, two conventional adaptive and active noise control methods, i.e. notch filter based active control method and artificial neural network based active control method, are analyzed. Taking into account of the characteristics of these two methods, an artificial neural network algorithm is used instead of Least Mean Square(LMS) algorithm of notch filter. Finally, these three methods are comparatively evaluated by using actual noise signals from substation. The results show that the proposed method has better stability and suppression effects of substation noise compared with other two conventional methods mentioned.

Key words: substation noise, notch filter, artificial neural network, adaptive noise control
