Wide-band line model implementation in Matlab for EMT Analysis

The Wide Band (WB) or Universal (ULM) Line Model currently is the most general line model available in EMTP for simulating transient responses of power transmission lines and cables. Since this model is still subject to further improvements, an experimenting prototype of it has been developed in Matlab environment. This development is reported here and the paper also offers a comprehensive description of the WB model. Two application examples are provided here, one involving an aerial line and the other one an underground cable.
