Abstract	The digital protections SEL are equipped by synchronization units GPS in the selected and suitable substations of Czech Transmission System CEPS. These complex units realized the measurement of synchrophasors PMU (Phasor Measurements Unit). This paper is aimed to analyse of synchrophasors and also to calculation of parameters of 400 kV line, V430 — „HRD-CHR“, which is measured on both ends. The data filtration and analyse is perform on commercial available SW toolboxes of MATLAB, e.g., Spectral Analysis is perform on Signal Processing Toolbox. The equations for calculation of lines parameters (impedance Z, admittance Y, lines temperature T) are perform directly on MATLAB. The next development steps are procedures of protections, local automatons, etc. The theory and algorithms are take from available technical documents of company SEL. The presented results are basis for contractual documents and building up the (inter)national WAMS (Wide Area Monitoring System) and/or WAPS (Wide Area Protection System).
