Exoerience With The Analysis Of Small Signal Stability In Longitudinal Power Systems: A Case Study With The Mexican Interconnected System, Arturo Roman Messina
A. R. Messina
In this paper a fundamental study of the small signal stability characteristics of a longitudinal system representing a major equivalent of the Mexican power system is presented. The special characteristics of the Mexican system are emphasized and a number of studies regarding the nature and sources of low frequency oscillations are discussed. These studies reveal the emergence of an undamped swing mode #tvolving the interaction of several machines and their controllers spread out over a large geographical area. The influence of system structure and loading, load effect and the
