Abstract
The present disclosure provides a method and a system for quickly determining transient stability of a half-wavelength transmission system. The method includes: obtaining power and a power angle of a feeding-end generator of a half-wavelength transmission system; and determining transient power angle stability and a power angle instability mode of the half-wavelength transmission system by using a constructed index system, where two power angle instability modes, that is, an instability mode 1 and an instability mode 2, are specifically constructed for the half-wavelength transmission system based on an equal area method. Based on the equal area method, the present disclosure constructs two instability modes specific to the half-wavelength transmission system, so as to accurately describe transient power angle characteristics of the half-wavelength transmission system under a severe fault, and characteristics of the two instability modes are significantly different from those of an AC transmission mode.
