A methodology to evaluate harmonic penetration in power networks

The paper presents an iterative process to calculate the voltage magnitudes and phase angles at each bus in a power network for each harmonic frequency (include fundamental frequency). The method indicated in the paper is based on Newton-Raphson method. A six-pulse line commutated converter and a twelve-pulse phase control delta-star connected converter are studied. They are regarded as harmonic sources in the paper. The algorithm is illustrated by taken a five-bus-five-line model.
