Power System Transient Stability Analysis (PST) Main Program

This is the main program for PST (Power System Transient Stability) analysis within a MATLAB-based environment, designed to conduct transient stability studies on power system models. The program implements numerical integration methods like Runge-Kutta or trapezoidal integration to solve differential-algebraic equations, allowing engineers to analyze specific fault scenarios and obtain critical parameters for generators and system nodes.

The program features modular architecture with configurable fault settings and simulation parameters, making it applicable to various power system configurations. It assists power system engineers in evaluating transient stability performance through multiple simulation runs with different initial conditions, providing valuable insights for system design and optimization. The algorithm includes fault application/clearing logic and post-disturbance trajectory tracking to ensure accurate stability assessment.

When utilizing this program for transient stability analysis, users must carefully verify input parameters including machine data, network topology, and fault specifications to ensure reliable results. The program incorporates visualization capabilities through MATLAB plotting functions, generating time-domain plots of rotor angles, bus voltages, and other key variables for intuitive result interpretation and enhanced understanding of system dynamic behavior.
