Corona noise characteristics in high voltage PLC channel

The paper presents the algorithm for estimation of frequency and time characteristics of the corona noise in high voltage power-line carrier (PLC) communications. In the frequency domain corona noise is represented with power spectral density and with Gaussian noise voltage with variable root mean square (RMS) value in time domain. The analytic method for estimation of the corona noise appearing at the line terminals in frequency and time domain is given. Simulations results are compared with the measurements on actual 400 kV power line.
