Abstract:
synchronous generator plant ٤٤٠ MW In this essay, the dynamical behavior of neka thermal power connected to an infinite bus under symmetrical three-phase short circuit that nonlinear system to ensure machine dynamical performance the possible occurrence of an error or Large disturbances, to maintain synchronizing, and stability are considered, It is necessary to provide a complete model of a synchronous generator, in order to calculate the steady-state and transient parameters using the equivalent circuit referred to the axis d-q, along with the finale equations for the rotor reference coordinate system, with regard to the flux linkages, the state variable is used. to study the dynamic behavior of software Matlab / Simulink, ٤٤٠ MW synchronous generator model, is simulated and analyzed. That in order to evaluate the dynamic performance of synchronous machines in real-time of the error in the peak positive voltage applied to a phase, then behavior of the damper and excitation windings against Symmetrical three-phase short circuit in transient mode from start fault to each steady state, are examined
