The Distributed Parameter Line block implements an N-phase distributed parameter line model with lumped losses. The model is based on the Bergeron's traveling wave method used by the Electromagnetic Transient Program (EMTP) . In this model, the lossless distributed LC line is characterized by two values (for a single-phase line): the surge impedance Zc = and the phase velocity v= 1/. The model uses the fact that the quantity e+Zi (where e is line voltage and i is line current) entering one end of the line must arrive unchanged at the other end after a transport delay of d/v, where d is the line length. τ= Three-Phase V-I Measurement Measures three-phase currents and voltages in a circuit Description The Three-Phase V-I Measurement block is used to measure three-phase voltages and currents in a circuit. When connected in series with three-phase elements, it returns the three phase-to-ground or phase-to-phase voltages and the three line currents. The block can output the voltages and currents in per unit (p.u.) values or in volts and amperes. Three-Phase Sequence Analyzer Measures the positive-, negative-, and zero-sequence components of a three-phase signal Description The Three-Phase Sequence Analyzer block outputs the magnitude and phase of the (denoted by the index 1), negative- (index 2), and zero-sequence (index 0) components of a set of three balanced or unbalanced signals. The signals can contain harmonics or not. Scope Displays signals generated during a simulation Description
