Abstract
Transmission lines’ non-negligible distributed capacitance can increase the risk of broadband resonance in power systems. However, the distributed parameter characteristics and frequency-dependent characteristics are commonly ignored in the transmission line modeling during the analysis of resonance, which may lead to inaccurate stability assessment and pseudo oscillations in simulations. In this paper, a harmonic frequency range transmission line model suitable for real-time simulation is proposed. First, a simplified calculation method of parameters based on system structures is expanded. Afterwards, a detailed equivalent circuit of the multi-phase model is implemented in real-time simulation to meet the requirements of decoupling and parallel computing. Finally, the electrical parameters are modified based on the harmonic frequency to improve the Bergeron model and the proposed model is developed accordingly. Simulation results show that the proposed model is highly suitable for time-domain simulation and high-order harmonic analysis.
