Abstract
The simulation model of 220 k V and 500 k V parallel power transmission lines on the same tower in Hunan power grid is built during two different phase faults along with disconnection of both the double-circuit transmission lines. The power flowing and transient stability are analyzed after faults. The effects on the security and stability of power system are studied when double-circuit transmission lines are disconnected on the same tower.
