Abstract:It is a great inductance of supplying power through rotating the rectifier to exchange the load of the armature winding of the exciter, because of armature existence of reactance in the winding of exciter , make rotatory rectifier at the phase of transfering to, electric current can change suddenly, produce change photo corner, this make output looks voltage , phase electric current wave form to exchange exciter distortion has taken place, the calculation of the exchange exciter originally designed has solved two following problems mainly: (1)What the voltage of direct current excitation given definitely according to the main generator and direct current excitation electric current, calculate out the output which is exchanged the exciter and exchange looks electric potential , looks electric current , and capacity P of the exciter; (2)How to calculate the armature which is exchanged the exciter to reflect, power factor, and necessary excitation magnetism tendency.
