Modelling of the acoustic impact of transformer stations

Abstract

Elaborates a mathematical model for simulating noise propagation around transformer stations. The mathematical model was first elaborated in APL on the basis of a large number of noise measurements of existing transformers and transformer stations. It takes into account noise reflection, noise diffraction and ground effects on propagation. In addition, further readings are presently being taken in order to determine the effects of topography and climatic conditions on long-distance noise propagation. At the present time, the FORTRAN version of the program is being worked out, with the alternative possibility of a much more simplified version of the stations in terms of nominal voltage and total electric power
