Computation of Maximum RMS Current and Peak Voltage on Transmission Lines under Nonsinusoidal Conditions

This paper presents two numerical methods for computing the maximum overall rms current, and an algorithm to find the maximum peak of the total voltage on a transmission line under nonsinusoidal conditions. The only prerequisite is that the measured or calculated values of the individual harmonic voltages and line currents at one end of the line are assumed to be known. The proposed methods guarantee convergence to the global maxima of the rms current and peak voltage. The numerical algorithms are demonstrated by an example.
