  • Abstract
    Transient stability enhancement by 120-degree phase rotation is described. The concept is to disconnect two generators or two groups of generators when loss of synchronism is imminent (large rotor angle difference due to a fault or other disturbance). The systems are then reclosed with 120-degree phase rotation. Stability can be improved because fast valving, excitation control, or governor control is allowed more time to become effective.
