摘要：
Based on the trajectory information of the power system, this paper analyzes transient stability prediction and new generation transient stability control for large power system. This method, which is independent of system parameter and model, can tell the transient stability of the power system quickly and give the control strategy. At first, system instability is detected by the characteristics concave or convex of the critical machine trajectory of the post-fault system. Then, the multi-variables self-memory numerical predictive formula is derived to accelerate the speed of recognizing the transient stability of the power system. What's more, the control strategy by the closed-loop control system is given based on transient kinetic energy when the power system is unstable.
