| Abstract: | The paper presents simulation results of de-excitation of end-short-circuit accident and no-load ceil accident of large-scale turbogenerator.Dynamic differential coefficient equations were created for the 6-rank mathematical model of turbogenerator,de-excitation model of linear or non-linear resistor and the saturation of damping windings and field winding.Finally an example of de-excitation simulation of a 600MW turbogenerator was carried with dynamic simulation program for power system.Simulate results in... |
