A new analytical model for predicting electromagnetic interference from corona on electric power lines has been developed. The corona is modeled as electric dipoles located on the surface of the power line conductor which is located above a homogeneous 1ossy Earth. The position and driving current of each dipole are described statistically. Expressions are found for the spectral density of the fields radiated by the corona and the currents induced on the power line. The main contribution of the new model is that it is valid in frequency ranges (i.e., 2-30 MHz) for which no model presently exists and for distances and directions from the power line which are essentially unrestricted. The model is shown to agree well with an empirical formula which was developed from the limited experimental data available. related to weather conditions and conductor surface electric field via an empirically derived "generation function" [IEEE, 1973; EPRI, 1975]. The surface field can be calculated from power line design parameters. The result is a formula for corona generated electromagnetic interference near a power line. Clearly, results based on this theory are limited. The assumed characteristics of the source are rudi-OLSEN AND WU: INTERFERENCE FROM POWER LINES 341 POWER LINE CONDUCTOR ' t/,t CORONA DISCHARGES /////// • t t f' AIR (•o,P"o)

“…First, determination of corona induced currents that are usually related to an excitation function. The excitation function defines the intensity of the corona on the HV power line and was determined experimentally [3], [4]. The second stage contains the computation of interference electromagnetic fields that are caused by corona induced currents.…”

“…The analytic approach for analysis of the corona induced currents proposed by Adams [3] is based on the electromagnetic theory. This paper introduced a "generating function", later named the excitation function that is used for representation of a corona current source distributed along the line.…”

This paper presents an algorithm for the computation of frequency and time characteristics of the corona noise in power-line carrier communications. In the frequency domain, the corona noise is represented with a power spectral density and with a Gaussian noise voltage with variable root mean square value in the time domain. Simulations results are compared with measurements on an actual 400-kV power line. Index Terms-Corona noise, high-frequency power-line modeling, power-line carrier.
