Model accuracy depends on the number of PI sections used for the model. Several PI circuits, each representing a small section of the line.Ī PI section consists of a series R-L branch and two shunt C branches. Of the line with a finite number of states can be obtained by cascading This model cannot be simulated as a linear system because a delayĬorresponds to an infinite number of states. Normally consists of a delay equal to the wave propagation time along the

The model of a line with uniformly distributed R, L, and C parameters You add the circuit breaker later in Simulating Transients. The Simscape > Electrical > Specialized Power Systems > Passives library. Resize the various components and interconnect blocks byĭragging lines from outputs to inputs of appropriate blocks. Once the dialog box is closed, notice that the L and C components haveĭisappeared so that the icon now shows a single resistor. Select R for the Branch Type parameter and set the R parameter according to

Which is already in your circuit1 window. The resistance Rs_eq of the circuit can be obtained The amplitude to be specified for a sinusoidal source is its peak valueĬhange the name of this block from AC Voltageįrom the Simscape > Electrical > Specialized Power Systems > Passives library, set its parameters as shown in Circuit to Be Modeled, and name it The AC Voltage Source block according to the values shown in Set the Amplitude, Phase, and Frequency parameters of Open a new blank model to contain your first circuit andĪdd the AC Voltage Source block from the Simscape > Electrical > Specialized Power Systems > Sources library.
