Gas turbines and the Nigerian grid systems

The grid system in which generating stations and major consumer centres are integrated is employed by the National Electric Power Authority in generating and distributing electricity in Nigeria. Gas turbines constitute more than half of the generating sets. The Nigerian grid is prone to instability which causes disturbances in the system and gas turbines are known to be sensitive to such disturbances. This paper is the result of a study of the effects of the instability of the grid on the gas turbine sets.
