Abstract

This paper, examines the stability of the existing 330kV Nigerian network system when subjected to small disturbance such as gradual load and generation increase. Modal analysis method is employed to carryout the analysis using the NEPLAN software. Various scaling factors for load and generation ranging from 0.4 to 0.6 andfrom 0.6 to 2.0 respectively were used to test the stability ofthe system. The results showed that all the generating nodes have negative real parts ranging from -0.001 to -1.404 and damping ratio from 0.054 to 0.211 which falls within the acceptable value of 0.3 and above with the exception positive eigenvalue to the negative side ofthe complex plane (S-plane).
