Title:
Representation of Transient Stability for Power System Dynamics Using Numerical Integration Method and Damping
Author Name:
S.Padhi, B.P.Mishra
Abstract:
ABSTRACT Analysis of transient stability of power systems involves the computation of their nonlinear dynamic response to large disturbances, usually a transmission network fault, followed by the isolation of the faulted element by protective relaying. For transient stability analysis, non-linear system equations are solved. In addition, large discontinuities due to faults and network switching and small discontinuities due to limits on system variables appear in the system model. Bus voltages, line flows and performance of protection systems are of interest in addition to the basic information related to the stability of the system. In this paper detailed transient stability analysis is done whereby the classical model is slightly improved upon by taking into account the effect of damping towards transient stability response. Characteristics of the various components of a power system during normal operating conditions and during disturbances have been examined, and effects on the overall system performance are analyzed. Keywords: - Transient Stability, damping, short circuit fault, Synchronous machine etc.
