Abstract :
Concerned with a 3 phase to ground permanent fault occurred at the two terminal of the 500 kV Luohe-Yingzhou transmission line in the Anhui power grid, the instability mechanism of the Anhui power grid when such a fault occurred is analyzed from the conventional point of view and also with the EEAC theory. The qualitative and quantitative explanations are also given to the cause of the stability difference when the fault occurs at different locations on the concerned line.
