Abstract

Summary

The action of a power system stabilizer (PSS) is to extend the angular stability limits of a power system by providing a
supplementary damping to the oscillation of synchronous machine motors through the generator excitation. PSS controller
design, method of combining the PSS with the excitation controller (AVR), investigation of the voltage of the network,
how much load in the form of loading parameter are presented in this paper. Power system analysis toolbox (PSAT) was
used to analyze the network to compare when PSS is not included and when it is included in the network. The network
considered is the Imo state (Eastern part of Nigeria) network. The network consists of three (3) generators and eleven
buses. Simulation results show that when PSS is not used all the buses were violated running a continuation power flow
(CPF) method, but when PSS was added , there was no violation at the point of collapse. The loading factor increased
when PSS is added (6.0513pu) as compared to when PSS is not added (1.0561pu). It can be concluded from the result that
PSS will greatly improve the existing network both in the area of stabilizing the voltage and withstanding additional load
in the network.
