Optimization Analysis on Layout of 220kV Outdoor Substation for Noise Control at the Boundary

The noise in substations has become one of the most concerning problems field power grid. In this paper, principle substation layout optimization based on maximum acoustic ray shielding method is established premise sound wave propagation rule complicated air medium to meet requirements relevant national environmental standards for at boundary substation. By establishing simulation analysis model 220kV outdoor substation, level before and after compared analysed, distribution inside outside obtained. results show that optimized can effectively reduce which provides a control design
