Abstract :
The damping characteristic of a single-machine infinite bus system is analyzed, and the relation graph of damping torque to transmission power is plot. The influence of changing tie-line power flow on the low-frequency oscillation modes of Central China Power Grid is researched, by way of changing power flow in one section and others remaining the same. The proposed method can be used for the actual operational planning and scheduling.
