Abstract

The optimization of transient stability of grid transmission system is the strongest and the weakest point of power transmission grid. Considering the protection of transmission system, relay operation adjustment is discussed for the emergency situation of cascade failure, island operation of power generating unit and load shedding of connected load with independently operating power generating units. Cascade condition of power transmission grid and auxiliary power supply for the startup of tripped generators by independently operating generators and non-conventional power generators by organizing favorable transmission grid configuration and economic and social impact of blackout condition is discussed.
