Abstract
To study the frequency and damping characteristics of power cable, high-order RLC circuit models are commonly required, which involves high computational burdens for modelling and analysis. In this paper, a reduced-order modelling method for power cable is proposed on the basis of Prony analysis (PA), vector fitting (VF) algorithm and balanced truncation (BT) algorithm. The state space model of power cable is first obtained by fitting terminal frequency responses using PA and VF instead of directly building mathematical model; Then the low-frequency characteristics is maintained using BT algorithm. The fitting accuracy can be improved by increasing the order. The proposed method is able to reduce computational burdens for power cable modelling, which thus improves modelling and analysis efficiency. Simulation results are given to validate the effectiveness of the proposed modelling method.
