Application of Transient Energy Function in Regional Power Grig

摘要：

　　With expanding scale of modem power sy stem and cross-region connection of power grid,the system often run closer to the ultimate state.So the security and stability problems become a focus of power system.This paper proposes an accurate regional-equivalent-system model,and the transient energy function is constructed based on this model,using above energy function the transient energy and critical energy can be calcul ated,and the units stability can be determined.Finally this method is applied to 8-machine-36-node system.The validity is confirmed by PSASP simulation.
