This model is based on PI-section. As shown in the figure below, there are two ports for current measurement.
Symbol | Description | Unit |
ID | Line name | a unique name |
|---|---|---|
| Status | Connect/Disconnect status | Initial value 1 (0 for disconnected) |
From bus | Sending bus | a unique name |
To bus | Receiving bus | |
R (pu) | Series resistance | p.u. (network base) |
X (pu) | Series reactance (2*pi*f*L) | |
B (pu) | Capacitive charge (2*pi*f*C) |
Available I/O Pins
