“…The saturation curve has been also represented, with a special focus on the determination of the air core reactance [7], [8], leading to a low value of this parameter L air , due to technological considerations. This leads also to a low value of the parameter L sat , which is the last slope of the saturation curve, leading respectively to 0.119 p.u.…”

This document describes the modelling of the 400 kV up-stream network for the energization of a 340 MVA transformer, using a Thevenin equivalent and also its detailed representation; after the validation of the complete network under steady-state conditions, a comparison between measurements made on site and transient simulations have also been performed, giving very satisfactory results, especially when a detailed modelling of the network is considered, as the transformer considered is highly non linear; non linear aspects are discussed.
