IEEE 123-Bus System Simulink

Abstract

The IEEE 123-bus system is a large and complex distribution system that is representative of real-world systems.It is a large system consisting of overhead and underground single phase, two phase and three phase laterals along with step voltage regulators and shunt capacitors. The 123 bus test feeder is characterized as given in [1] by:

Load Types a. All spot loads b. Wye and delta connected c. Mixture of constant power, constant impedance and constant current. Line Types a. Three-phase overhead (all combinations of a, b, c) b. Two-phase overhead (Combinations of a, b, c) c. Single-phase overhead (a-n, b-n, and c-n) d. Three-phase underground Voltage Regulators a. Three-phase, gang operated b. Three single-phase, wye connected c. Two single-phase, open wye connected d. Single-phase, line-to-neutral connected Shunt Capacitors a. Three-phase b. Single-phase
