Power System Transient Stability Analysis Using ETAP Software

Abstract

Power-system stability is a term applied to alternating-current electric power systems, denotin g a condition which the various synchronous machines of the system remain synchronism, or in step, with each other. Conv ersely, instability denotes a condition involving loss of synchronism, or falling out of step. Occurrence of a fault a p ower system causes transients. To stabilize the system load flow analysis is done. Actually practice the fault generally occu rs the load side. As we controlling load side which will lead t o complex problem order to avoid that we are controlling t he generator side. This paper covers the transient stability ana lysis of 400 kV substation of Soja. A three phase fault is located at specified bus to analyze the effect of fault location critical clearing time on the system stability.
