IEEE 39-Bus System

Since R2024b

This example shows how to model a 39-bus three-phase power system network. This example is based on the IEEE benchmark test case. For more information, see "IEEE PES Task Force on Benchmark Systems for Stability Controls" by Hiskens [1].

Model Overview

The IEEE39BusSystem model comprises four subsystems:

• Generators - Comprises ten generators and associated automatic voltage regulators (AVR), exciters, power system stabilizers (PSS), governors, and prime movers

• Grid - Models the power system network by using transmission line, transformer, and busbar blocks

• Loads - Represents all the loads of the network

• Measurements - Measures the terminal voltages and rotor speeds of the generators

Simscape™ Electrical™ first performs a load-flow analysis for the model and determines the steady-state operating point for a given loading condition. The simulation then starts from this steady-state operating point. At time 5 s, a three-phase-to-ground fault occurs at Bus-16. The fault then clears in 0.1 s. After the simulation, the software adds an annotation that shows the resulting load-flow solution to each busbar in the model.
