Abstract :
Complete results are presented on the phase portrait of a class of large nonlinear dynamic systems that includes the power system. The connection between the constant energy surface and the stability boundary of the power system is explored. This gives valuable insight into classical stability tests, which are based on the constant energy surface. An approach to stability monitoring of the power system derived from these results is outlined.<>
