Phase-Plane Methods to Analyse Power System Transient Stability

摘要

Phase plane analysis is one of the most important techniques for studying the behavior of dynamic systems, especially in the nonlinear case. Recent research shows that transient stability problem of a power system following a large disturbance such as a fault can be solved with greater efficiency based on phase plane analysis. In this paper, we will consider the phase plane-analytical method and phase plane-delta method to analyze the transient stability of IEEE 5 bus system with two generators and a three phase fault created at a bus. The classical model representation of power system is used here. To simplify the analysis, all nodes other than the generator internal nodes are eliminated using Kron reduction formula.
