Transmission Line Modeling Requirements for Testing New Fault Location Algorithms using Digital Simulators

| Recently, new fault location algorithms for transmission lines, that take advantage of synchronously sampled data were proposed. To thoroughly evaluate the sensitivity of the algorithm to fault parameters and the power system features, it is important to have an accurate model for the power system, especially the transmission line of interest. In this paper, the requirements placed on the transmission line model to make it suitable for algorithm testing, are discussed. Model validation plays an important role too, since the accuracy of the algorithm depends on the accuracy of the model. The paper presents a sample system, and the results of EMTP testing of a certain class of algorithms on the sample system. Digital simulator testing of the algorithms is required before actual eld trials. Thus, there are some requirements that a simulator set-up should meet, which are also discussed
