Analysis of diode breakdown of strong excitation circuit of synchronous generator new type superposition strong excitation system and the function of shunt capacitance
In order to study the feasibility of synchronous generator new superposition strong excitation system of the self-shunt excitation system, this essay focus on the diode breakdown of the new type superposition strong excitation circuit, and shunt capacitance effects of the waveform. Through the matlab simulation show that the influence of diode breakdown in strong excitation circuit on the excitation system is very bad, especially when the main circuit diode takes place short-circuit fault, superposition strong excitation will be failure, so we must pay attention to it. And the rectified current flowing through a shunt capacitor has no apparent effect on the function of smoothing waveform. So on the engineering and theory, this kind of smoothing waveform method is not used.
