Impact of fault location on transient stability of synchronous generator

This paper presents the impact of fault in various lengths of power line on transient stability of synchronous generator. The same events on two power lines are compared by means of transient simulations, the difference is at fault distance on assessed power lines considering the generator. In the first part are compared fault impacts and fault tripping in the fast zone of distance protection. Fault tripping by protection failure at the end of the assessed power line is compared in the second part. All simulations are mutually compared in terms of significance of their impact on transient stability of synchronous generator.
