Abstract
Audible Noise (AN) produced by corona discharges is one of the many obstacles in designing UHV transmission lines. Therefore line designers must calculate the corona AN using prediction formulas. Many of the existing formulas are limited due to some constraints in use and prediction errors and are focused mainly on heavy or stable rain. Although the corona AN level emitted in fair weather is significantly less then during rainy conditions, according to the ISO 1996 std, the AN results of fair weather are required as well in order to calculate the long-term level. Some of existing formulas have been developed from test cage data whereas others have been developed from data gathered on full-scale in real world conditions. In this paper a database was built using measured data gathered in either bad and fair weather from 400 kV lines exist in Poland. In this paper some results of applying artificial neural network competition using gathered AN data will be presented to develop a new formula for predicting AN during bad and fair weather conditions. Calculated corona AN levels using this new formula and some existing formulas will be compared with measured data.
