Abstract | This paper presents a new model for the representation of very short transmission lines and cables. This model is an extension for the constant parameter line model in the electromagnetic transient programs such as the EMTP. It overcomes the limitation of using a time step size not larger than the travel time. Unlike the nominal pi;-circuit line model, which is commonly used to represent short lines and cables, the new line model represents the electromagnetic transients more accurately. Simulations have been performed comparing the proposed line model with existing line models, for a case where the new line model provides more accurate results |
