Dynamic Harmonic Domain Modeling of Transients in Three-Phase Transmission Lines

This paper presents a traveling wave based transmission line model which includes harmonics in transient state. The line model is interfaced with a nonlinear load and both are simulated through the dynamic harmonic domain technique. This technique permits the user to follow step-by-step the harmonics of the propagating waveforms during transient conditions. An illustrative example involving a transmission line network with nonlinear loads is presented and the proposed model is compared with its time domain counterpart.
