Research on Control Technology of Substation Noise Based on Active Noise Reduction

In recent years, more and more urban substations have seriously affected the normal life of the surrounding residents, of which the most serious is the impact of substation noise on human health. Therefore, noise exceeding the standard has become an important problem to be solved by the substation. For the use of sound absorption, sound insulation of the traditional passive noise reduction methods for low-frequency noise control effect is not good, and may affect the ventilation and lighting, and active noise reduction in the noise control has many advantages, so this paper from the active control aspects of the start, based on the principle of acoustic phase cancellation interference of the active noise reduction technology to achieve the management of the substation noise, analyse the factors that will have an impact on the effect of noise reduction and through the simulation of the study concluded that It analyses the factors affecting the noise reduction effect and derives the noise reduction law of each influencing factor through simulation, and formulates the optimal noise reduction scheme, which is of great significance to the field of substation noise control.
