Description
Summary:The Vietnam power system is in phase of development. The risk of angle instability is evident due to the sizable length of the 500kV transmission lines, the resulting considerable amount of power transmitted through these lines, the fast increase of load demands and the special configuration of the Vietnam power system. There are the interactions of different power plants and the oscillations of generators between northern and southern regions. This is why the angle stability must be studied in detail in order to ensure a security and safety in the operation and to find the solutions to improve the stability of the system. In this paper the transient stability study for this system is presented. In order to improve the angle stability, the application of FACTS devices such as SVC and UPFC are investigated
