Accurate validation of Electromagnetic Transient models of cascaded power transmission systems

Abstract

Conventional transmission line model validation methods are not suitable for validating Electromagnetic Transient (EMT) models of cascaded transmission systems such as cross-bonded cables due to accumulation of errors in repeated matrix multiplications. This paper introduces an approach to accurately validate EMT models of such cascaded transmission systems. This technique utilizes four composite propagation functions and the characteristic admittances to represent the transmission line model. Results from electromagnetic transient models are compared with those from the novel technique and conventional validation techniques to demonstrate the superiority of this approach.
