An analysis of transient stability using center-of-inertia: Angle and speed

Abstract

Instability in the system may cause the rotor angle of the machine to accelerate or decelerate depending on the mechanical power and electrical power; most seriously could result to tripping of the machine This paper evaluates the impact of disturbances and types of loads to system stability using Area-based COI-referred Transient Stability Indexes: COI angle and COI speed. The analysis is carried out using PSS®E 32 software on IEEE 118 Bus Test System at system conditions with and without dynamic loads. The network is initially divided into significant areas based on the geographical. ©2010 IEEE.
