IeeeTopologyDiagrams 4.0.1

IEEE 33-Bus single-line diagram drawing primitives based on Baran.1989 (Main Version)

IeeeTopologyDiagrams

IEEE 33-Bus single-line diagram drawing primitives based on Baran.1989 Figure 2.

Install

pip install IeeeTopologyDiagrams

Quick Start: Generate the Complete Diagram

Generate the standard IEEE 33-Bus single-line diagram with one command:

IeeeTopologyDiagrams-fig2

Or use Python API:

from IeeeTopologyDiagrams.reproduce_fig2 import draw_ieee33bus_diagram

# Generate and save to current directory
draw_ieee33bus_diagram()

# Or specify output path
draw_ieee33bus_diagram('my_diagram.png')

Python API

from IeeeTopologyDiagrams import (
    draw_switch,                  # horizontal closed switch
    draw_switch_vertical,         # vertical closed switch
    draw_switch_open,             # horizontal open switch
    draw_switch_open_vertical,    # vertical open switch
    draw_bar_node,                # vertical bus bar node
    draw_bar_node_switched,       # horizontal node + switch module
    draw_node,                    # load node
    draw_tf_node,                 # transformer node
    draw_substation_vertical,     # vertical substation (SS1)
    draw_substation_horizontal,   # horizontal substation (SS2)
)
