Summary:This paper presents some results of our ongoing research on the dynamic performance of the Vietnam power system. The study involves simulations of N-1 events in the 500-220kV transmission system, especially the loss of an 500kV circuit, which in reality has caused a large scale blackout in the Southern grid of Vietnam, in May 2013. The simulations reveal some interesting results, regarding the operation of transmission line and generators protection systems. The sequence of relay operation can change the course of a large scale event drastically. The results provide us with new insight to revise relay settings that helps reduce the risk of cascade tripping.
