Transient stability analysis of IEEE 9 bus power system (original) (raw)

Power-system stability is a term applied to alternating-current electric power systems, denoting a condition in which the various synchronous machines of the system remain in synchronism, or "in step," with each other. Conversely, instability denotes a synchronism, or falling "out of step." Occurrence of a fault in a power system causes transients. To stabilize the system load flow analysis is done. Actually in practice the fault generally occurs in the load side. As we are controlling load side which will lead to complex problem in order to avoid that we are controlling the generator side. It is widely accepted that transient stability is an important aspect in designing and upgrading electric power system.After major recent blackouts caused by power system instability lie importance of this phenomenon.Transient stability has been the dominant stability problem on most system and has been the focus of much of industry‘s attention concerning system stability assessment is concern with behaviour of synchronous machines after they have been experiencing a large disturbance in system. This project covers the modelling and the transient stability analysis of the IEEE 9 bus test system using MIPOWER.
