Synchronous Generator Simulation Model in Simulink

This article presents a synchronous generator simulation model developed using MATLAB Simulink. The model is ready-to-run, enabling users to observe the normal operational characteristics of synchronous generators. Through parameterized subsystem blocks implementing Park's transformation and swing equations, the simulation can replicate various fault scenarios including short-circuit events and excitation system failures. The model incorporates monitoring scopes and data logging functions for real-time analysis of electromagnetic torque, rotor angle oscillations, and terminal voltage responses. Users can modify machine parameters (inertia constants, damping coefficients) and fault timing through mask dialog boxes to study dynamic stability. With its comprehensive simulation capabilities and visualization tools, this model serves as a powerful platform for power system analysis, facilitating deeper understanding of synchronous generator performance under both normal and contingency operating conditions.
