Abstract

Based on trajectory information for the electric power system, this paper analyzes Transient Stability Prediction and new generation transient stability control of large power system. This method, which is independent of system parameter and model, can tell the transient stability of the electric power system faster and give the control strategy by the closed-loop control system. Firstly, System instability is detected by the characteristics concave or convex of the critical machine trajectory of the post-fault system. Secondly, to accelerate the speed of recognize the transient stability of the power system, the self-memory numerical predictive formula of multi-variables is derived. Thirdly, the control strategy by the closed-loop control system is given based on transient kinetic energy, when the power system is unstable.
